Science, Made Tasty.

Beer Geek Wednesday

Beer Geek Wednesday is our Head Brewer Mark Howes’ weekly excursion into the science, history and occasional absurdity behind beer. From hops, malt and fermentation to flavour perception, brewing chemistry and whatever obscure technical rabbit hole he’s disappeared down this week, no subject is too nerdy and no detail too insignificant.

Some weeks it’s practical. Some weeks it’s historical. Some weeks you’ll learn considerably more about yeast metabolism than you ever intended.
