Most winemakers use substances called fining agents during production, but not all of these are suitable for vegans.
To help you find a vegan wine worth a place at your table, we've rounded up the best available from our taste tests below.
Whether you're in the mood for a rich red or a celebratory champagne, our expert taste tests will help you pick the perfect option for your budget.
Why is wine not vegan?
Wines appear cloudy following fermentation because the proteins in them clump together. These are natural ingredients and not harmful, but brands prefer to sell a clear, pure wine.
To deal with the haze, manufacturers use fining agents to help the proteins clump together and sink to the bottom of the wine, making the sediment easier to remove.
Some commonly used fining agents contain animal products, which means certain wines are a no-go for vegans. During the fining process, egg albumen (derived from egg whites) is sometimes used for red wine, while milk protein is used for white wine. Other animal-derived fining agents include bone marrow and fish oil.
If you're shopping for a vegan wine, you'll want to look out for a drink that's produced using animal-friendly fining agents. Below, we've rounded up some suitable red wines and champagnes which are listed as vegan or vegetarian on the bottle.

Our panel of independent experts blind-tasted 19 champagnes, 10 sparkling white wines and 10 red wines in September 2021. Not all of them were vegan-friendly, so we've only included the vegan ones here.
We disguised all the bottles before serving so that they didn’t know which brand they were tasting. Each expert assessed the drinks in a different order. At the end of the tasting, they discussed their ratings and agreed on a score for each bottle.
Our experts were:
Kathryn McWhirter Wine expert and co-author (with Charles Metcalfe) of 'The Wine and Food Lover’s Guide to Portugal'
Charles Metcalfe Speaker, author, and co-founder of the International Wine Challenge

Peter McCombie Master of Wine, restaurant wine consultant, speaker, writer and critic.
How to recycle wine bottles
Glass bottles can usually go in your household recycling bin. If your council doesn’t accept them, you can take them to a local bottle bank.
The recycling process can vary depending on where you live, so make sure to check with your local area if bottles require rinsing first and whether metal screw caps should be replaced or recycled separately.
Natural corks can’t go in your recycling bin. You can recycle natural corks through Recorked UK – either by posting them or dropping them off at your nearest collection point.
Synthetic corks, which are made of plastic, can’t be recycled. They should be disposed of in your general waste bin.
