Wine has microplastics, but at low levels — and in the biggest recent study it tested cleaner than almost any other packaged drink. A 2025 study by France's ANSES agency, published in the Journal of Food Composition and Analysis, found wine held only about 8.2 microplastic particles per liter, far below beer (~82.9), lemonade (~45.2) and cola (~31.4). Wine was the exception among glass-bottled drinks, which were otherwise contaminated by paint shedding off their metal caps — wine's cork skips that source. The catch: a 2020 Food Chemistry study found at least one synthetic particle in every white wine sealed with a plastic (polyethylene) stopper, so the closure still matters. The studies measured how much plastic is present, not proven harm — and with wine, the alcohol is the far bigger health story.
Wine seems like it should be one of the cleaner drinks: fermented grapes in an inert glass bottle, sealed with a piece of tree bark. For once, the intuition holds up. When French researchers measured microplastics across bottled water, soft drinks, iced tea, lemonade, beer and wine, it was the glass-bottled drinks that surprised them — most were higher than the same drinks in plastic, because tiny flakes of paint were shedding off the caps. Wine was the standout exception, sitting near the bottom of the range, because it is sealed with a cork instead of a painted metal cap. The counterintuitive lesson runs opposite to what that same study found for glass bottles generally: for wine, the classic corked glass bottle really is the clean choice.
This guide walks through exactly what the studies found — the ~8.2 particles per liter that put wine near the bottom of the pack, the synthetic-cork finding that complicates it, and where the plastic actually enters — whether the amounts are worth worrying about (the honest answer is calmer than the headlines), and the handful of small changes that cut what little there is.
The bottom line up front: wine's microplastics come mainly from the closure and the winemaking equipment, not the grapes or the glass — so the levers are choosing a natural-cork glass bottle over synthetic-corked or bag-in-box wine, and not storing wine in plastic. But keep it in proportion: wine's levels are low and the alcohol matters far more, so spend your real effort on the drink you have every day. For the bigger picture, see why tap water is a top source, our ranking of which foods have the most microplastics, and the room-by-room kitchen plastic detox guide.
Does wine have microplastics, and how much?
Yes — but less than most drinks, and the headline study is recent and specific. In May 2025, researchers at France's food-safety agency ANSES published a study in the Journal of Food Composition and Analysis that measured microplastics across a wide range of drinks sold in France — bottled water, cola, iced tea, lemonade, beer and wine. Wine came out among the lowest of all, at roughly 8.2 particles per liter, next to about 82.9 in beer, 45.2 in lemonade and 31.4 in cola. The result surprised the team, because for most drinks the glass-bottled version was higher than plastic or cans — the opposite of what everyone expected.
The explanation was the closure, not the drink. For the high beverages, the researchers traced the particles to the paint on the outside of the metal caps, which sheds tiny flakes as caps scuff against each other in storage; the particles matched the cap paint by color and polymer. Wine, sealed with a cork rather than a painted cap, dodged that source almost entirely, and the researchers noted that corked wine showed little sign of contamination. A separate 2020 study in Food Chemistry complicates the good news, though: examining white wines capped with polyethylene (plastic) stoppers, it identified at least one synthetic particle in every bottle by micro-Raman spectroscopy. So “low” is not “zero,” and the type of closure is exactly where it turns.
Where do the microplastics in wine come from?
Mostly from the closure and the winemaking chain — not the grapes and not the glass. The glass bottle is inert, and the 2025 data showed that a natural cork adds almost nothing, which is why corked wine tested so clean. The weak points are the plastic parts. Synthetic corks, made largely of polyethylene, and the plastic liners inside screw caps sit in direct contact with the wine and can shed particles — the 2020 Food Chemistry study found synthetic particles in every polyethylene-stoppered white wine it examined. Bag-in-box and pouch wines go further, storing the wine in a plastic bladder for weeks or months.
Before the wine ever reaches a bottle, the cellar adds its own plastic contact. Modern winemaking moves juice and wine through plastic hoses, pumps, tank liners, and filtration pads, and open tanks can collect airborne synthetic fibers from the room. None of this is unique to wine — it's the same “the drink is fine, it's the equipment and packaging” pattern we see across beer and other bottled drinks. The difference is that wine's dominant potential source, the closure, is one you can actually see and choose. The table below sorts out where the plastic in a typical bottle of wine originates.
| Source | What Happens | Contribution |
|---|---|---|
| Synthetic corks & screw-cap liners | Polyethylene stoppers and plastic cap liners touch the wine directly; a 2020 study found synthetic particles in every plastic-stoppered white wine | Major — the main lever |
| Bag-in-box & pouch bladders | The wine sits in a plastic bladder for weeks or months, in constant contact with a large plastic surface | Moderate to major |
| Cellar equipment | Plastic hoses, pumps, tank liners and filtration pads move and filter the wine during production | Moderate |
| Airborne fibers in the winery | Synthetic fibers can settle into open tanks and vats during fermentation and aging | Minor to moderate |
| Natural cork & the glass bottle | Both are essentially inert; corked wine in glass tested among the cleanest drinks in the 2025 study | Negligible |
Which wines have the most microplastics?
The pattern tracks the closure and the packaging, not the color of the wine or the grape. A bottle sealed with a synthetic cork or a screw cap with a plastic liner has more opportunity to pick up particles than one sealed with natural cork; and bag-in-box or pouch wine, sitting in a large plastic bladder, has the most plastic contact of any format. Red versus white matters far less than how the wine is stored and stoppered. So the cleaner choice isn't a fancier wine — it's the classic format the 2025 study measured as lowest: a glass bottle with a natural cork.
Put the numbers in scale before they alarm you. At about 8.2 particles per liter, a standard 150 ml glass of wine works out to roughly one microplastic particle — and a widely cited 2019 analysis estimated the average person already consumes tens of thousands of microplastic particles a year from food, drink and air combined. Wine is a real but very small contributor to that total, well below the water you drink all day. What makes the finding useful isn't the size of the number — it's that the one meaningful source, the closure, is so easy to see and choose.
"Wine doesn't get its microplastics from the grapes or the glass — it gets them from the plastic stopper, the plastic bladder, and the cellar hoses. Skip the plastic closure and most of it disappears."
Is wine still fine to drink?
On the microplastics alone, wine is one of the drinks you'd worry about least — it measured near the bottom of the pack, and a glass carries on the order of a single particle. Nothing in these studies is a reason to change your wine habits for fear of plastic. The honest caveat has nothing to do with microplastics: alcohol carries its own well-documented health considerations, and those dwarf the plastic question entirely. If you're weighing whether to drink wine, that is the conversation that matters, not the particle count.
So the takeaway isn't “wine is dangerous” — it's that if you do drink it, the plastic part is easy to minimize and not worth losing sleep over. That mirrors a theme across this site, and one of the most common microplastics myths: a scary-sounding measurement isn't the same as a proven risk, the way we've argued that a reassuring label like “BPA-free” doesn't automatically mean safe. The dependable move isn't chasing a perfect, plastic-free wine; it's choosing natural cork over synthetic, keeping wine out of plastic, and cleaning up the bigger, steadier source — the water you drink all day.
Are the microplastics in wine dangerous?
Here's where honesty matters. The 2025 and 2020 studies were designed to measure how many particles are present and what polymers they are — not to test what those particles do once they're inside a person. On the narrow question of harm from the microplastics in wine, the research doesn't have a verdict, and no one should read one into it. Wine's measured levels are also low, a small figure next to overall exposure.
A widely cited 2019 analysis in Environmental Science & Technology estimated the average person already swallows tens of thousands of microplastic particles a year from food and drink combined, with tap and bottled water a large driver; a glass of wine is a tiny contributor within that total. What we do know more broadly is that microplastics are increasingly detected throughout the human body — in blood, organs, and even the brain — so trimming avoidable sources is sensible even while the particle-harm question stays open. But wine is not one of the big sources, and the alcohol is the more meaningful health factor by far.
You don't need a plastic scare to act on this one. Wine's microplastic load is low; if you drink it, choose a natural-cork glass bottle over synthetic-corked or bag-in-box wine and you've handled most of it. Then spend the rest of your effort on the bigger, more constant sources in our kitchen plastic detox guide, starting with the water you drink all day.
How do you reduce the microplastics in wine?
Because the meaningful source is the closure, the fixes are about format, not giving up wine. Choose a glass bottle with a natural cork over one with a synthetic cork or a plastic-lined screw cap — the natural-cork glass bottle is the format that tested cleanest in the 2025 study. Skip bag-in-box and pouch wine when you can, since the wine sits in a large plastic bladder. Decant into a glass carafe if you like, and never store leftover wine in a plastic container — keep it in the glass bottle or a glass vessel. These moves cost nothing and handle the part of the problem you can actually control.
The highest-leverage move, though, isn't about wine at all — it's the drink you have every hour you're awake. Filter the tap water you drink and cook with, because the water going through your body all day is a far bigger and more constant microplastic source than an occasional glass of wine, and it's the one you can genuinely clean: a pitcher certified under NSF/ANSI 401 or built around a rated membrane pore size cuts particle counts sharply. See our guide to the best water filter pitchers for microplastics and the broader water filter roundup — or, if you’d rather filter at the tap, the best faucet water filters. Carry filtered water in glass instead of plastic, and you've closed off the sources that actually add up. The picks below are the simplest, longest-lasting ways to do all of that.
Fix the sources that actually matter
A natural-cork glass bottle handles most of the plastic in your wine — but the water you drink all day is the bigger, steadier source. Start where it counts: filter your tap water and keep your drinks in glass instead of plastic.
The swaps that cut the most plastic around wine
You can't filter wine at home, and there's no such thing as a “microplastic-free” bottle to buy — the real lever is choosing natural cork and keeping wine out of plastic. So instead of padding this out with products that don't exist, here are the real, currently-sold tools that address the sources you actually control: certified water filters for the bigger daily source, plus glass and platinum-silicone storage to keep your drinks and leftovers off plastic. Prices and availability change, so check current listings.
1. Epic Pure Water Filter Pitcher — Best Overall for Microplastics
Best Overall
Reviewers point to published independent lab data and a filter rated around 150 gallons, far longer than a Brita, as the reasons they trust it, and several describe the slow, deliberate drip as reassuring rather than annoying. The honest downsides: owners report the filtration is genuinely slow and not the pick if you want a glass of water in a hurry, and third-party complaints mention cracked plastic, flip-top lids that stick, and water that spills or leaks from the lid when you pour a full pitcher.
The clearest evidence on this list: Epic posts its independent lab results publicly, so you can see the 99.9% microplastic-removal data instead of trusting a slogan on the box.
Why it's safe: The hollow fiber membrane physically blocks microplastic particles down to ~1 micron, while the carbon stage handles chlorine, lead, and PFAS — all in a BPA-free Tritan body.

The water you drink and cook with all day — the glass you fill at the tap, the pot you boil, everything behind your daily hydration — is usually a bigger and steadier microplastic source than an occasional glass of wine, and it's the input you control most tightly, which makes a good filter the highest-leverage swap on this list. The Epic Pure is the clearest choice: its dual-stage design uses a hollow fiber membrane as the primary microplastic barrier, and Epic publishes the independent lab results to back the 99.9% removal claim — transparency most competitors don't match.
2. Waterdrop Chubby 10-Cup Pitcher — Best Filter Life
Best Filter Life
Owners like the look and the long 200-gallon filter life, and roughly 80 percent of reviews land positive, with the common praise being clean-tasting water at a low cost per gallon. The honest gripes: several owners warn the handle can feel loose or strain under a full pitcher, so they lift with two hands; some report the pour spills if you tip too fast; and the change-filter indicator light draws complaints for not lighting or not staying lit.
A membrane blocks particles by pore size rather than by claim list, and its 200-gallon filter runs about 4 to 5 months — the lowest ongoing cost on the list.
Why it's safe: A hollow fiber membrane is a physical barrier to particles, while the carbon composite handles chlorine, heavy metals, and PFAS — all in a BPA/BPS-free body.

If you're filtering the water you drink and cook with all day, you'll run water through a filter constantly — so filter life matters, and the Waterdrop Chubby leads on it: a hollow fiber membrane on Waterdrop's own published lab data, plus 200 gallons per filter (about 4–5 months for most households). The "filter while you pour" design works just like a familiar counter pitcher, but with a membrane that's actually tested for microplastics.
3. Aquagear Water Filter Pitcher — Best Value
Best Value
Owners choose it for broad contaminant removal and clean taste, and some lab testing found it did not clog. The honest downsides: the most repeated complaint is slow filtration, described by one reviewer as a mixed bag between people waiting minutes and people waiting hours, and it can worsen as the filter ages; and the design draws gripes, with the pour-spout cover popping out and spraying water and a lid that fits poorly and can pop off mid-pour.
Change the filter half as often as most pitchers — 150 gallons per cartridge means fewer replacements, lower annual cost, and less to remember.
Why it's safe: A 5-stage filter with a sub-micron membrane stage captures microplastics, lead, fluoride, and chlorine, in a BPA-free body with USA-made filter media.

The Aquagear costs more upfront but its 150-gallon filter life means lower annual replacement costs than most competitors, and the pitcher body is guaranteed for life. It uses a 5-stage filter with a sub-micron membrane stage that targets microplastics, heavy metals, and fluoride — a good fit for households that don't want to track filter changes constantly.
4. Lifefactory Glass Bottle 22oz — Best Glass Bottle
Best Glass Bottle
Wine is a small, occasional source; the water you drink all day is the steady one — and this is how you carry the clean version. It’s made from borosilicate glass, the same material used in laboratory glassware, which is thermally stable, chemically inert, and completely free of BPA, BPS, and any polymer contact with your drink. It imparts no taste, so water tastes like water. The protective silicone sleeve adds grip and guards against shattering.
The screw cap contains a small polypropylene component — the only plastic in the system, and it sits at the exterior closure rather than the drink surface. Rinse it like any cap and it stays a non-issue. Dishwasher-safe, and sturdy enough for daily desk-and-bag use.
Owners love that water tastes clean with no plastic aftertaste and that the silicone sleeve makes the glass easy to grip and survive the occasional drop. The honest downsides: it’s heavier than a plastic or steel bottle, the glass can still break if dropped on a hard edge, and some reviewers find the flip-cap spout narrow or report the cap can leak if not fully closed.
Carry the filtered water you made at home instead of buying bottled — no plastic contact, no leaching, and it cleans up in the dishwasher.
Why it's safe: Borosilicate glass is completely inert — it never leaches, never sheds microplastics, and imparts no taste. The only plastic is a small cap component at the exterior closure, not the drink surface.

Wine is worth managing, but water is the source you touch most. Carrying filtered water in a reusable glass or stainless steel bottle — or a dedicated filtered water bottle — gives you grab-and-go hydration without the PET — no shedding, no leaching, no plastic aftertaste — so the packaged bottle stops being the default.
5. Glasslock Oven Safe Container Set (3-Pack) — Best Glass Storage
Best Glass Storage
Longtime owners like that the glass bodies are oven-, microwave-, and freezer-safe and that the snap-lock lids seal tight. The honest downsides run through the lids, not the glass: reviewers report cracked lids, snapped locking tabs, and mold building up in the rubber gaskets if they are not dried well. Some buyers also received sets with a locking piece missing, and several flag slow, hard-to-reach customer service when they needed a replacement part.
Three stackable glass containers in one box — enough to store a week of leftovers and prepped ingredients without a single plastic tub.
Why it's safe: Your food sits on inert tempered glass, not plastic — so warm, acidic, watery foods can’t leach or pick up shed particles. The BPA-free lids seal with a food-grade silicone gasket that only touches the rim.

Glass storage is the direct fix for keeping your food and drinks off plastic: store leftovers, prepped ingredients and open pantry items in inert glass instead of plastic tubs or cling wrap, and reheat with the lids off so warm food never sits against plastic. At roughly ten dollars per container, it's also the cheapest way to retire your plastic food tubs in one purchase.
6. Stasher Reusable Silicone Bag Starter Kit — Best Silicone Bag
Best Silicone Bag
For freezing food in portions, stashing leftovers you won't finish in time, or anything you’d reach for a plastic bag — Stasher’s platinum-cured silicone is the upgrade: sturdier than any disposable bag and free of the chemicals that migrate from plastic. The patented Pinch-Loc seal is genuinely airtight and leakproof, so it keeps food from drying out.
It’s freezer safe to -70°F and goes straight to the microwave or a 425°F oven. The starter kit covers the everyday sizes — sandwich, snack, and stand-up half-gallon — so you can retire a whole box of single-use bags in one purchase.
Owners like that the platinum silicone bags go from freezer to microwave and replace throwaway plastic for years. The honest gripes: smell and stain retention come up often, with reviewers noting garlic and strong odors linger even after washing; the pinch-lock seal can be fiddly to open and close; and the seams are slow to dry, which can invite mildew if you do not air them out.
Store prepped produce, snacks, and batch-cooked food in airtight silicone instead of plastic film — then thaw and reheat in the same bag, no transfer needed.
Why it's safe: Platinum-cured silicone — the highest-purity, chemically inert grade — with no plastic, PVC, BPA, lead, latex, phthalates, or PFAS.

Prepped produce, snacks, and batch-cooked food are exactly the things people stash in flimsy plastic bags and cling film. A multi-size silicone kit replaces the whole box at once, seals airtight, and goes from freezer to microwave in the same bag. For the full lineup, see our guide to the best silicone food storage bags.

The honest verdict
Does wine have microplastics? Yes — but in the 2025 ANSES study it measured among the lowest of any packaged drink, about 8.2 particles per liter, next to roughly 82.9 in beer and 45.2 in lemonade, and a 2020 Food Chemistry study still found a synthetic particle in every plastic-stoppered white wine. But the crucial detail is where it comes from. It isn't the grapes or the glass — wine's dominant potential source is the closure, which is why corked wine in a glass bottle tested so clean and synthetic-corked or bag-in-box wine carries more. The studies measured presence, not proven harm, and wine's levels are low next to overall exposure. So the accurate takeaway is proportion, not alarm — and the fact that the one meaningful source is easy to see and choose.
The practical response is easy, because the culprit is the plastic closure. Choose a glass bottle with a natural cork over a synthetic cork or plastic-lined screw cap, skip bag-in-box and pouch wine when you can, decant into glass if you like, and never store leftover wine in plastic. Keep it in proportion, too — wine's microplastic load is low, and if you're weighing whether to drink it, the alcohol is the real health question, not the plastic. And above all, filter the tap water you drink and cook with, since the water going through your body all day is the bigger, more constant source and the one you can genuinely make cleaner. You don't need a plastic scare to act on this one — a natural cork handles most of it.
Cut the plastic that actually adds up
A glass of wine is small next to the water you drink all day. A certified filter and glass storage make clean water and plastic-free drinks your easy default.
Frequently Asked Questions
Yes, but at low levels. A 2025 study by France's ANSES agency, published in the Journal of Food Composition and Analysis, measured microplastics across packaged drinks and found wine among the lowest at about 8.2 particles per liter — far below beer at around 82.9 and lemonade at 45.2. Wine was the exception among glass-bottled drinks, which were otherwise heavily contaminated by paint shed from their metal caps; wine's cork avoids that. A separate 2020 Food Chemistry study, however, found at least one synthetic particle in every white wine sealed with a plastic (polyethylene) stopper, so the closure still matters.
Because of the closure. In the 2025 ANSES study, glass bottles of soft drinks and beer were surprisingly high in microplastics — but the source turned out to be the paint on the outside of the metal caps, which sheds flakes as caps rub together in storage. Wine is usually sealed with a cork rather than a painted metal cap, so it skips that dominant source. The glass itself is inert in every case; the contamination rode in on the cap paint, and wine simply doesn't have one.
They can. A 2020 study in Food Chemistry examined white wines capped with polyethylene (plastic) stoppers and, using micro-Raman spectroscopy, identified at least one synthetic microplastic particle in every bottle; an optical count found up to several thousand particles per liter, though that method could not confirm each one was plastic and the numbers are debated. Natural cork is not plastic and does not shed microplastics the way a synthetic stopper or a plastic screw-cap liner can, which is one reason natural-cork wine tested so clean in the 2025 ANSES data.
Mostly from the closure and the winemaking equipment, not the grapes or the glass. Synthetic corks and the plastic liners inside screw caps can shed particles into the wine, and bag-in-box wine sits in a plastic bladder. During production, wine moves through plastic hoses, tank liners, pumps and filtration pads. Airborne fibers can also settle into open tanks. The glass bottle itself is inert, and a natural cork adds essentially none — which is why wine in a corked glass bottle measured among the cleanest drinks tested.
You can't filter wine at home, so the levers are what you choose and how you store it. Favor wine in a glass bottle with a natural cork over synthetic-corked or bag-in-box wine, decant into a glass carafe if you like, and don't store wine in plastic. But keep it in proportion: wine's microplastic load is low and alcohol itself is the far larger health consideration. The biggest lever is the drink you have every day — filter your tap water, since the water going through your body all day is a much bigger and steadier microplastic source than an occasional glass of wine.
The studies measured how many particles are present, not what they do inside the body, so they don't establish harm — and wine's measured levels are low, a small share of overall exposure that a 2019 analysis put at tens of thousands of particles a year from food, drink and air combined. With wine, the health conversation is dominated by the alcohol, not the plastic. Microplastics are increasingly detected throughout the human body, so cutting easy sources is sensible, but wine is not one of the big ones — filtered water and less plastic-packaged food matter far more.
