Is all Prosecco vegan?

No. Prosecco is made from grapes, but some producers clarify their wine with animal-derived fining agents such as gelatin, egg white, milk casein or isinglass. A Prosecco is only reliably vegan when the producer says so or the bottle carries a vegan certification.

Is La Marca Prosecco vegan?

We found no vegan statement on its official page. When we checked in October 2026, La Marca's own Prosecco page gave no vegan or fining information. Ask the producer or look for a vegan logo on the back label.

Is Mionetto Prosecco vegan?

We found no vegan statement on its official pages. The Mionetto US product pages we opened in October 2026 did not mention vegan status. Some retailers tag certain Mionetto bottles as vegan, so check the back label of the bottle you buy.

Do US wine labels have to list fining agents?

No. Wine Spectator notes that allergen labeling is voluntary for wine in the United States, so a US label usually won't tell you whether egg, milk or fish products were used in fining.

Is organic Prosecco automatically vegan?

Not necessarily. Organic describes how the grapes were grown, while vegan status depends on what was used to clarify the wine. Some organic Proseccos make no vegan claim on the producer's site, so check for both.

Vegan Prosecco: Is Prosecco Vegan? Brands That Say So

Prosecco is made from grapes, but that doesn’t make every bottle vegan. The catch is fining: some winemakers clarify wine with animal products such as gelatin, egg white, milk protein or fish isinglass, and in the US none of that has to appear on the label. So the honest answer is that some Prosecco is vegan and some isn’t, and the only reliable way to know is a clear statement from the producer or a vegan logo on the bottle. Below you’ll find which brands say so on their own websites, which ones make no vegan statement on their official pages, and how to check any bottle yourself.

Is Prosecco vegan?

Nothing in the basic Prosecco recipe needs animal products. According to the Consorzio that protects Prosecco DOC, the wine is made mainly from the Glera grape, with a short list of other varieties allowed up to 15% in total, and it gets its bubbles from a second fermentation in large sealed tanks (the Martinotti method). DOC stands for Denominazione di Origine Controllata, Italy’s system of protected wine names.

Whether a particular Prosecco is vegan depends on what happens after fermentation, when the winemaker clears and stabilizes the wine. That step is where animal-derived products can come in.

What fining is, and why it matters for vegans

Young wine contains tiny particles and proteins that can make it hazy. Wine Spectator’s Dr. Vinny describes fining as adding a substance that attracts those solids and proteins so they clump together and sink. The clear wine is then drawn off the sediment.

The Australian Wine Research Institute (AWRI) names the main animal-derived fining agents as gelatine (collagen), egg albumin, milk casein and fish isinglass. It notes that many of them are potential allergens, and it is researching non-animal alternatives such as yeast and plant-based proteins.

Fining agent	Where it comes from	Animal-derived?
Gelatin	Animal collagen	Yes
Isinglass	Fish (Wine Spectator mentions sturgeon bladder)	Yes
Egg white (albumin)	Eggs	Yes
Casein	Milk	Yes
Clay (such as bentonite)	Mineral	No
Seaweed	Plant	No
Yeast or plant proteins	Non-animal alternatives studied by the AWRI	No

Do traces stay in the wine? In principle, no. Dr. Vinny says the agents should leave with the sediment, although some countries still require allergen labels as a precaution. Many vegans avoid any wine that has been in contact with animal products anyway, which is why the fining agent matters even if nothing is left in the glass.

Note: Labeling rules differ by country. The AWRI says Australian winemakers must declare these agents on the label. In the US, Wine Spectator notes that allergen labeling for wine is voluntary, so the back label of a bottle sold here usually won’t tell you.

Prosecco brands that say they are vegan

How we checked: in October 2026 we opened each brand’s own website and product pages, and we list a brand here only if the producer itself states that its Prosecco is vegan. Retailer tags and third-party vegan directories don’t count for this list, because we couldn’t check where their information came from or how current it is.

Bellissima

Bellissima’s Prosecco page lists a Prosecco DOC Brut and a Prosecco Rosé DOC. Both product cards say “Certified Vegan” next to “100% Organic Grapes”, and the site repeats that its wine is “100% vegan and organic”. The page doesn’t name the certifying body, so look for the logo on the bottle if that matters to you. In our view, this is the clearest vegan statement of any Prosecco brand we looked at.

Della Vite

Della Vite, founded by Chloe, Poppy and Cara Delevingne, describes itself on its homepage as “vegan and sustainable” and says its winery uses “100% vegan processes”. The founders’ story says they worked with a winemaking family in Valdobbiadene, in northern Italy. The range includes a Superiore labeled D.O.C.G. (the stricter Italian tier above DOC), along with a rosé, a “Zero” and several spritz drinks.

Brands with no vegan statement on their official pages

These are some of the best-known Prosecco names in the US. On the official pages we opened in October 2026, we found no vegan statement. That doesn’t mean the wines aren’t vegan. It means the producer doesn’t say so where we looked.

Brand	What its official page showed
Mionetto	The US product page for Prosecco DOC Organic Extra Dry lists 11% alcohol and Glera from certified organic vineyards, with no vegan claim.
La Marca	The Prosecco page describes the flavors but gives no vegan, fining or ingredient information.
Bottega	The Bottega Gold Prosecco DOC page (labeled Brut) lists 11% alcohol and 10–14 g/l of sugar, with no vegan claim.

We haven’t checked every brand. For any producer not listed here, look for a vegan statement on its own site or a logo on the bottle. Retailers and vegan directories sometimes tag Prosecco as vegan, and they may be right. We’d still check the bottle in front of you, because a claim for one wine or one market doesn’t always carry over to the next.

How to check any Prosecco yourself

Read the back label. Look for a vegan logo or a certification mark. That is the strongest sign you’ll get in a store.
Check the producer’s own product page. Brands that are proud of being vegan usually say so there. Make sure the page matches your bottle, since one producer can make several Proseccos.
Ask the producer directly. Ask which fining agents they use for that specific wine, not just whether it is “vegan friendly”.
Don’t read too much into “organic”. Organic is about how the grapes were grown. Mionetto’s organic Extra Dry, for example, makes no vegan claim on the producer’s US page.

Tip: Screenshot or note the producer’s wording when you find a vegan statement. Brands change suppliers and winemaking over time, and a dated note makes it easy to recheck later.

Choosing a good vegan Prosecco

We haven’t given value verdicts on this page. Our verdicts follow how we rate wine: a published critic score for a named vintage plus US prices from at least two retailers, and we only publish them when that evidence is in hand. For Proseccos that meet that bar, see our guide to the best Prosecco under $20, then check each bottle’s vegan status with the steps above.

A few practical points once you’ve found your bottle:

Serve it well chilled. We’d open it just before pouring, so you keep as many bubbles as possible.
Don’t count on leftovers lasting long. Our guide to how long wine lasts after opening covers sparkling wine stoppers and fridge storage.
Pair it simply. In our view, a dry Prosecco is at its best with salty snacks, fried food and light starters. Our wine and food pairing guide explains why acidity and bubbles work so well with fat and salt.
