The other day, I met a guy, who makes craft beer by himself at home.I knew the brewery got yeast extract when they product beer. So I asked him to give me that one, it could be as yeast for bread baking. He gave me the beer extract yeast and malt barley which also came from beer brewing. The malt barley was already cooked and crushed to brew beer.
I needed only small amount of beer yeast. Because it is so vigorous. When I prepare the sour dough, yeast was starting bubbling at the room temperature. I had to scale ingredients and put it away into the fridge quickly. And it taste like tangy beer. If I put too much, bread become tangy taste.
To make the sour dough starter with beer yeast, I used 100g bread flour and 1 tea spoon of beer yeast for 1 loaf.
The malt barley contained water, so I reduced water when I make the final dough.
The crumb color becomes brown from beer yeast.
Polish becomes light brown.
