From the Notebook Limited - bottle is Vegan Friendly

Company email (July 2023)
"I’m assuming you are referring to the Hangin’ Pizzeria in Betws-y-Coed as the restaurant in question?
All of the beers (in can and bottle form) From the Notebook sell to the Pizzeria and its sister establishment the Alpine Coffee Shop, brewed at Allendale Brewery, are suitable for vegetarians and vegans.
Isinglass is only used at the brewery in cask production."
