Molson Coors UK has some vegan options

"To clarify your question: Carling is brewed in a brewery where isinglass is not used at any stage of the process. This means that, from a production process perspective, the beer is free from animal derived finings. "However, our formal Vegan accreditation currently applies only to the Cobra family of beers. "In practical terms, the beer is produced without isinglass or animal matter, but we can only label and promote products as “Vegan” once the full certification is complete. We hope that this clarifies your query."

"We are pleased to confirm that the new Caffrey’s Black Stout is vegan friendly."

"Staropramen is not certified by the vegan society as being suitable for vegans. Isinglass finings are used during the brewing process."

"Unfortunately, Coors is not vegan friendly. Any of our products that are vegan friendly will have certified by the vegan society displayed on them."

"Caffrey's is not certified by the vegan society as being suitable for vegans. Isinglass finings are used during the brewing process. As you may be aware, finings are a traditional product and a natural raw material, that has been used in the process of clarifying beer and wine for thousands of years. It is one of the techniques used to ensure the bright and sparkling appearance that many consumers really appreciate."

"Madri Excepcional is not certified by the Vegan Society as being suitable for vegans. Isinglass finings are used during the Madri Excepcional brewing process. As you may be aware, finings are a traditional product and a natural raw material, that has been used in the process of clarifying beer and wine for thousands of years. It is one of the techniques used to ensure the bright and sparkling appearance that many consumers really appreciate. However, not all brands are produced with finings, and we can confirm that from our wider portfolio, our brands Cobra, Aspalls and Rekorderlig cider ranges are certified by the vegan society."

"Staropramen products are suitable for vegetarians and vegans. No animal products are used in production."

"Unfortunately, Staropramen which is brewed in the UK is not suitable for vegans."

"All Staropramen products with exception of COOL GREP have vegan/vegetarian status."

"Unfortunately Coors Light in the UK is not currently suitable for vegans."

"We can confirm that Blue Moon is only centrifuged & not filtered so is not processed using any animal products. Staropramen is currently filtered using Isinglass finings."

Company email (December 2017) "The only products we have that are suitable for vegans are:- Carling Cider Apple Carling Cider Black Fruits Cobra Grolsch"

"We can confirm that all our Cobra Lager products produced in the UK are approved by the vegetarian society, but have yet to have the same certification to be suitable for vegans."

"We can confirm that unfortunately Carling does still use isinglass finings in the clarification process during production, therefore would be unsuitable for vegans / vegetarians."

"We can confirm that unfortunately Coors Light Lager would not be suitable for vegans / vegetarians as it uses isinglass finings in the clarification process during production. However the following beers in our portfolio are produced without using isinglass finings which may be of interest to you: Blue Moon Cobra Grolsch"

"Here at Molson Coors UK we brew and package the Grolsch Premium Beer and can confirm that it is suitable for vegetarians and vegans."

"Unfortunately, Carling is unsuitable for Vegans as it does use isinglass fininings during its production."

"We can confirm that Cobra is suitable for Vegans."

"We can tell you that we don’t use animal-products."

1) Yes, we use isinglass 2) No animal ingredients are in the product itself Grolsch is our product which is suitable for vegetarians and vegans (In response to: 1) Are any animal products such as isinglass, gelatin or bone char used to filter Carling Black Label? 2) Are there any animal ingredients such as dairy, egg, or honey in Carling Black Label itself?)

"Grolsch is brewed using completely naturally processes and no animal by-products (isinglass, gelatin, cartilage, etc.) are used to brew the beer. For reference, Grolsch received the "Best Vegetarian Beer" award in 2003 from the UK Vegetarian Society (http://www.vegsoc.org/press/pressarchive/2003/pr50.html )." Additional email: re: Grolsch "I've been to the Grolsch Brewery (which is 10 km from my house) and asked if their beer is vegan friendly. They told me it is 100%." Another inquiry re: Grolsch Carling Black Label (which isn't vegan friendly) also stated that "Grolsch is our product which is suitable for vegetarians and vegans"
