Brewing up an APA with WHC Labs High Voltage dry yeast. It’s insanely quick - I put it in at 3pm and by 8pm there was CO2 coming out of the fermenter. 2 Days later and it’s down to FG. That was fermenting at 30 C, which is as high as my fermenting fridge goes. You can ferment at up to 36 C.
From brewing to keg within a week - what a world we live in!
Yes, it does! When it’s crushed, it’s not-so-slow release, mostly of oily matter that just stays inside if they are only cracked. And in the end, the powder could sink, or it could stay on surface, cling to tubing, clog filters, etc. And the regret of actually doing more work to grind on top of that!
There is also small increase of chances to contaminate the product, extra solid surface (negligible area in almost whole nuts versus non0negligible in powder) can harbor and somewhat protect species that are normally intolerant to alcohol.
