Shacklands Brewing has some vegan options

Company email (January 2022)
"Occasionally we will make a “ milkshake” beer, which uses lactose, which is of course milk sugar but we mark it as such, noting that it is not suitable for vegans. This is a once a year beer.
We also make kettle sours, which use lactbacillus for souring- as lacto bacillus is used in cheese making there is a chance that the lacto may have been cultured in animal by products, but we have been unable to get confirmation, so it’s likely best for us to state that all kettle sours using lactobacillus are not vegan friendly.
Other than those two items, we do not use any animal products by in any of our beers in any way.
These two beers are a small fraction of our Belgian inspired/ Belgian influenced array of beers.
We manufacture in one location so monitoring is easy.
As a vegetarian since 1985, I am quite serious about monitoring our use of any animal derived products."
