Hi all,
I'm doing my first commercial batch soon on a 500L system. The water at the brewery is incredibly soft:
Ca: 46
mg: 4
na: 9
cl: 11
so: 7
PH: 7.7
I know it's quite lucky to have this as base water, but i'm worried as my first batch is a pale ale with Enigma and H. Blanc hops which I want to shine.
I've not touched water chemistry before as the minerals / salts in the water at my home were much higher.
I'm pretty sure using gypsum and other salts is allowed (I'm in Germany so the purity law comes into play) if used before the mash.
Any tips on how much gypsum / calcium chloride to use and what I numbers I should be targeting?
Secondly, the owner of the brewery likes to get beers out of primary and into secondary after 7 days, and his fermentation room is a constant 15 degrees. Would US-04 do the job in 7 days? I've been told US-05 might not get it finished in time... any other tips for a good, fast working neutral ale yeast at that temp?
Thanks!
