Rebellion Lager (bottles) is Vegan Friendly

From their website (https://www.rebellionbeer.co.uk/beers/allergen-information.aspx, retrieved January 2021)

"Draught Beer - No : Not Vegan Friendly - We brew using traditional methods, one of which is adding the finings agent 'Isinglass' to help the beer clear. The isinglass is not vegan friendly, so our draught beer is therefore also not vegan friendly.

"Bottled Beer - Yes : Vegan Friendly. The process the beer goes through does not require isinglass and therefore is vegan friendly."

Company email (circa 2010)

"The simple answer is that all our beers are 'fined' at some stage with isinglass, so not vegan friendly I'm afraid! We do not use any of the other animal ingredients you eluded to in any of our beers."
