Not at the same time, I pitch the Sour Pitch at around 103F and then let it do its thing. I found the ph to drop down pretty low pretty quickly <2 days down to 3.5. once its down that low, I will pitch Voss and possibly heat it back up using my Glycol system.
Thinking about maybe letting it sour for a few days and then pitching Nova Lager on this next batch. ( i will have a bunch of nova from a double batch of my golden lager sitting around). Might be cool.
This next Sour is gonna be Passionfruit, Tangerine, lime, and a small amount of Vanilla. It is inspired by the hurricane drink.
