Notes

Experimental dark sour inspired by https://untappd.com/b/capital-brewing-co-hello-darkness-black-forest-black-ipa-sour/3162992

The 10ml Lactic Acid addition is added after the bash/boil to pre-acidify the wort. It probably isn't enough to get it down to the recommended 4.5 ph but I didn't want to over do it (I don't have a PH meter)

First time trying Brewtan

Mash and boil with NO hops
Cool to 35 degrees
Add Lacto
Wait until desired sourness is reached (check every 12 hours)
Add a little bit of sugar to bring it back to expected pre-boil OG
Boil again and add hops
Cool back down, pitch yeast and ferment as normal with yeast

3 of 5

The roasted malt flavour and fruity hops make a sort of Black Forest cake flavour that is awesome. Unfortunately the bitterness does not go well with the sourness. Next time Iâ€™ll take out all bittering hops and make them all whirlpool and dry hop additions. I might also add a small amount of lactose to sweeten it up a tiny bit.
