East London Quadrant Oatmeal Stout (cask) is Vegan Friendly

Company email (January 2024)
"All of our beers are now vegan. We made the change a few years ago so no surviving products out there that aren't."

Company email (March 2019)
"We would like to inform you that our Peacock English Pale Ale 4.2%, and Cowcatcher APA 4.8% are VEGAN in bottles."

Company email (April 2013):
"All but one of our beers use isinglass finings. Quadrant Oatmeal Stout is vegan friendly, though, as it not fined.

No other animal products are used."

Company email (October 2012):
"I'm afraid we do use isinglass to fine our beer in cask - sorry (I have tried without, but it just would not clear, and I'm afraid the majority of pub customers still want clear beer). We have one beer that we do not fine, Quadrant Oatmeal Stout, but we've only made it once so far and I'm not sure when it'll be made again.

Our bottled beers will be vegan friendly, though, as they will not be fined.

None of our products are made elsewhere."
