Winemaking traditionally involves using animal-derived ingredients such as gelatin and fish bladders to filter out unwanted particles. There are now more vegan wines on the market - but where do you start?

The glug of a bottle of wine pouring effortlessly into a glass is a sound that echoes into the souls of millions across the globe. But is wine vegan?

Long, bustling days and stuffy commutes are often spent dreaming of a glass a wine at the end of it all. Indeed, whether a delicate Provence ros or a tropical Marlborough sauvignon blanc, wine brings relaxation, good feels, and so much more.

Behind eclectic bars lay bubbles eagerly awaiting an overdue catch up with a best friend.It is relief, the start of weekends, the perfect accompaniment to a meal.

However, there are complicated processes behind that perfect Pinot. Some of these involve animal products. Heres everything you need to know.

Wine is made from ripe grapes plucked fresh off the vine. Next, the production process begins:

So it would seem, based on those steps, wine is vegan then, isnt it?

What customers arent often told is that the winemaking process commonly involves several animal-derived ingredients including blood, fish bladders, gelatin, eggs, and milk protein.

Importantly, it is during filtration when this occurs.

However, despite this, vegan wines are on the rise. Additionally, celebrities such as Cameron Diaz and Cara Delevingne have brought out their very own bottles with soaring sales.

There are several parts of the winemaking process that utilize animal products, meaning a vast number of wines red, white, and ros arent vegan.

Animal products are commonly used during fining, according to vegan YouTube sommelier Nicole Vranjican, also known as NikkiVegan.

The yeast from the grapes feeds on the sugar inside the grapes, which is when fining happens, says Vranjican.

Egg whites or fish bladders are often used to collect the dead yeast. But, there are vegan-friendly ways to do this too, Vranjican told Plant Based News..

Using bentonite clay is one example and many winemakers use these vegan-friendly ingredients for reasons that have nothing to do with creating a vegan product.

Eggs, casein, gelatin, and isinglass are common wine fining agents. As theyre removed before bottling, they dont have to be labeled.

Bristol-based wine expert and vegan Emma Stowell, who runs Vegan Wine Box, says the use of animal-based fining agents is debated in the wine world.

She says the process typically rids wines of unpleasant aromas and tastes.

Animal-based fining agents include:

Egg whites are used to remove sediment that slips through the filtration process. Sediment and tannins stick to the egg whites.

One barrel of wine can use several egg whites, theyre removed after fining is complete.

Casein is the main protein in cows milk. It removes unwanted sediment common in white and sparkling wines.

According to the Australian Wine Research Institute (AWRI), casein prevents oxidation and helps reduce bitterness. Additionally, it removes unwanted colors caused by sediment.

Gelatin is made by boiling pig and cow tendons into a gelatinous substance. Its use in wine is to remove bitterness from red varietals.

The AWRI says its the most aggressive of the protein-based fining agents.

Isinglass is another popular method for filtering wine. It comes from the swim bladders of fish. Isinglass helps prevent cloudiness in wine and beer. In addition, it removes protein and yeast.

In recent years, demand for vegan wines has skyrocketed, with Harpers estimating the market being worth 1.5 billion.

Many large retailers have separate tabs to make things easier for vegan shoppers, which reflects the plethora of more plant-based products now available on the market.

Supermarkets in the UK responded to the trend, with Tesco adding an array of vegan bottles as part of its Finest range. Additionally, SPAR rolled out its own affordable vegan wine range. The Co-op followed suit.

The Vegan Society explains it is becoming increasingly common for supermarkets to label their wines vegan.

The Vegan Society suggests plant-based customers find wine by looking for the vegan trademark a list of which can be found here.

A handy tool for finding vegan wine, including those without the vegan trademark, is Barnivore. The website contains a large database of different brands and informs users whether theyre vegan.

Vegan Wine Boxs Emma Stowell suggests asking at your local independent wine store, they will tend to have lists of which of their wines are vegan even if they arent labeled.

In the US, it is not mandatory for a winemaker to put much info on wine bottle labels, and that includes noting whether or not the wines have been made using animal-derived fining agents. However, in the UK, the government only calls for wine labeling to list allergens. Ingredients include eggs and milk. Unfortunately, this does not include gelatin or isinglass.

Countries such as South America and Georgia traditionally use bentonite clay as a fining agent. However, they dont always print it on the bottle. This is an example of the confusing labeling process, Stowell explains.

Winemakers from countries where veganism isnt as popular, wouldnt even consider labeling their bottles as such, she adds. Thankfully, sellers including Stowell are working with winemakers globally to resolve this.
