Does vegan butter go bad? How long an opened tub keeps

Yes, vegan butter goes bad, and the maker whose butter is cultured like dairy gives it the shortest run. Miyoko’s says an opened tub is good for 2 weeks. Earth Balance and Country Crock publish no opened shelf life at all, only “keep refrigerated”. Past the date, smell and texture decide.

The number to hold on to is 2 weeks. Miyoko’s FAQ says its products are good for 2 weeks once opened and should not be eaten beyond “a week or so” after the best-by date, opened or not. That is the cultured cashew butter, and it is a far shorter run than the old version of this page gave, which allowed an opened tub anywhere from 2 weeks to 6 months without a source for any of it. The oil-blend spreads sit at the other extreme. Earth Balance and Country Crock put no number on an opened tub anywhere we could find. The jar of vegan mayo on the next shelf has the same split between makers, covered in our guide to how long vegan mayo lasts once opened.

What 7 products say about storage

We read what 4 makers publish about their vegan butters. Only one gives a shelf life for an opened tub. The rest tell you to refrigerate and leave the arithmetic to you, so for those, the date on the pack is the only number you have.

Miyoko’s European Style Cashew Milk Butter, Salted

The one maker that answers the question. Miyoko’s says all its products are perishable and must stay refrigerated, an opened tub is good for 2 weeks, and nothing of theirs should be eaten more than about a week past the best-by date. Freezing adds 3 to 6 months of shelf life, and the salted and unsalted European style butters are on the list of products that freeze well. The ingredient list is organic coconut oil, organic cultured cashew milk, water, organic sunflower oil, sunflower lecithin, sea salt and natural flavors, with a “Contains: Cashews” line, and the 8 oz tub was $6.49 on the maker’s site in October 2026. The FAQ still calls it Plant Milk Butter while the product page has moved on to Cashew Milk Butter, so if the box in your fridge says one and the website says the other, it is the same product and the same 2 weeks.

If you buy butter one tub at a time and finish it slowly, this is the one that will go off before you do. Buy it for a week of baking, not for the back of the fridge.

Miyoko’s Oat Milk Butter, Salted

Same FAQ, same rules. Refrigerate, 2 weeks once open, a week or so past the date, 3 to 6 months extra in the freezer. It is a 12 oz tub built on organic high oleic sunflower oil and cultured oat milk, and the maker says it contains no tree nuts, wheat or soy as ingredients. Do the math before you buy. The tub holds about 24 servings of 1 tablespoon, and 24 tablespoons in 14 days is a lot of toast, so unless you bake, the freezer is part of the plan from day one.

Earth Balance Original Buttery Spread

Earth Balance says everything it makes is vegan, and the spread’s SmartLabel page carries a vegan claim and one storage instruction, “KEEP REFRIGERATED”. No opened shelf life, no freezer advice. The ingredient list is a canola and palm oil blend, water, salt, pea protein isolate, sunflower lecithin, lactic acid, vitamin A palmitate, natural flavors and beta carotene. The only shelf life figure Conagra publishes for Earth Balance that we could find is on its foodservice page: 365 days refrigerated, for a 30 lb cube. If you have a 30 lb cube, you now know. For the 10 oz tub, the date on the lid is all you get.

Earth Balance Vegan Buttery Sticks

The sticks are Certified Vegan by vegan.org, per their SmartLabel page, which also says “KEEP REFRIGERATED” and nothing else about storage. They are a palm, canola, soybean and flaxseed oil blend with soy protein isolate and organic soy lecithin, so these are not the ones for a soy-free kitchen; Earth Balance sells a separate Soy Free stick for that. The box of 4 sticks is 16 oz, and with no stated opened life, an unwrapped stick goes by the date and by your nose.

Country Crock Plant Butter Tub with Avocado Oil

Country Crock says all of its Plant Butters are vegan and dairy-free, its general FAQ says to refrigerate after every use and use a clean knife every time, and the Plant Butter tubs and sticks can be frozen. The Plant Butter page also asks itself “Does Country Crock Plant Butter need to be refrigerated?” and, on the day we read it, the answer box under that question was empty. The general FAQ answers it, so refrigerate. The avocado tub’s listed ingredients are a soybean, palm kernel, avocado and palm fruit oil blend, water, salt, pea protein, soy lecithin, lactic acid, natural flavor, vitamin E acetate, vitamin A palmitate and beta carotene. Avocado is third in a blend of 4 oils, so the word on the front is doing more work than the oil is. Buy it because you like how it spreads.

Country Crock Plant Butter Sticks with Olive Oil

The olive sticks list a palm fruit, palm kernel, olive and canola oil blend, water, salt, pea protein, glucose, sunflower lecithin, citric acid, natural flavor and beta carotene, with a “Contains Soy” line and a footnote telling you to refer to the packaging for the latest ingredient information. Take the footnote seriously. Several reviews on Country Crock’s own pages describe a changed recipe and a different seal under the lid this year; that is readers talking, not a company statement, but it is a reason to read the pack you are holding rather than the one you remember. Same storage rules as the tub: fridge after every use, freezer allowed.

Melt Organic Plant Butter Spread

Melt says you can freeze its butter to extend shelf life without losing quality, and to thaw it in the refrigerator. It also says not to leave the spread or sticks on the counter for long, because once melting begins the oils separate. The 13 oz spread is an organic blend of coconut, palm fruit, canola, sunflower and flaxseed oils with water, sea salt, sunflower lecithin, natural flavor, tocopherols, which the ingredient list calls a plant-based preservative, and annatto. Melt describes the product as dairy-free and free of all top-9 allergens; the pages we read never use the word vegan. The ingredient list reads as plant-only, and we would buy it, but if you want the word on the maker’s own page, this is not the brand that gives it to you.

Freezer and counter

3 of the 4 makers say their butter can be frozen; Earth Balance says nothing either way. Miyoko’s is the only one to put a figure on it, 3 to 6 months of extra life. Melt wants it thawed in the fridge, and that is the method we use for all of them.

Nobody gives you a counter time. Melt comes closest, with “not for long” and a warning that a melting spread separates and does not perform the same afterwards. For the rest we fall back on the FSIS rule for perishable food: no more than 2 hours between 40 and 140°F (about 4 and 60°C; the Celsius figures here are our conversions), and no more than 1 hour above 90°F (about 32°C). A butter dish on the counter in a cool kitchen is a long tradition, but every maker on this page says fridge, so the dish gets filled from the fridge and emptied the same day.

What the date on the tub means

A “Best if Used By” date tells you when the product will be at its best flavor or quality, and FSIS says it is not a purchase or safety date. Except for infant formula, federal rules do not require a date on food at all. If the date passes while the tub is in your fridge, FSIS says a product should still be safe if handled properly, until spoilage is evident.

Miyoko’s is stricter than FSIS and shortens its own window to about a week past the date. When the maker and the regulator disagree in that direction, go with the maker, who knows what is in the tub.

How to tell it has turned

The FSIS test is an off odor, flavor or texture. On a plant butter, the texture change to watch for is separation, which Melt describes as the oils splitting out once melting starts. A tub with oil pooled on top has been warm at some point, whatever the date says. Mold is the one sign with no gray area. FSIS does not list butter or margarine in its mold guidance, but it says foods with high moisture content can be contaminated below the surface and tells you to throw out jams and jellies rather than scoop. A cultured cashew butter is a moist, fermented food in a tub, so the whole tub goes. FSIS stops at jam; the whole-tub rule is ours.

A date does nothing for the other check. In September 2026, retailers including Wegmans and Natural Grocers pulled lot 1007871 of Miyoko’s Creamery Salted European Style Plant Milk Butter, 8 oz, UPC 857554005773, use by 11/05/2026, for potential presence of E. coli; Wegmans lists it as a recall and offers a refund at the service desk, Natural Grocers calls it a product withdrawal. Nothing we read for this article turned up an FDA listing or a statement on Miyoko’s own site. If you have a tub from that lot, take it back. Glance at the lot code on any tub you buy; we would still buy the brand, since it is the one that answered our question most clearly.

Buy the tub you will finish in 2 weeks, keep it in the fridge, and let the freezer hold the rest. If you are stocking up for a baking weekend, our roundup of the best vegan butter for baking covers which one to reach for.
