So I'm about midway through my partial mash; about a 25% to a third through my brew day. 4.5 lbs of grain for my partial; 1.4 gallons for the infusion mash.
Target temperature was 156*F for the alpha rest; I calculated 169*F for the necessary water temp. Only after adding the grains to the mash water did I realize my mistake: I was using refrigerated grains!! Temp came up to 149. I thought no problem, I'll put the oven temp up to 155*F and let it climb up over the next hour.
Mash time finishes, and I find out the grains never made it past 150! Wort is bitter, like no sweetness at all. So I put the pot back on the burner and try to monitor the temperature until it gets past 155, figuring I can throw it back in the oven for another 30 minutes. Apparently I took too long to stir or something because it shot right up to 180*F between checks!
Figuring I have now killed all the enzymes, I filtered out the grains and went right to sparge/mashout, where I'm waiting now. Since I'm using 8 lbs extract, I have resolved to RDWHAHB.
But tell me, did I botch this partial mash, or is there hope?
