We used Viking caramel 50 which is 20L, not the German CaraAmber.
Made starter of one pack of yeast with 1/2# DME - 18 hrs stir, 18 hrs off. Crashed. Didn't use the yeast calculator though, and I think we didn't pitch enough.
Mashed in at 162, hit 150 exactly. Added acid early and chemicals when mashing. No well-fitted jacket so we lost some heat, but only down to, well, 147, but not until the last 15 minutes. Held well.
Boiled for 2 full hours, from almost 10g. down to less than 6 (whoops). Last bit boiled off more quickly.
Cooled and into fermenter, chilled overnight to about 62 and pitched. Brought up to 68 over 4 days. Activity apparent in 12 hours - going great guns in 24!
Since the volume turned out less than I wanted the IBUs went from 50 to 70 - will be interesting to see how bitter it is.
Let it ferment at 68 for 5 weeks, crashed for 5 days and kegged.Tasted some heat, lots of sweetness, and not much else - kind of disappointing. Finished VERY high (38?), so I may try something else. Also didn't get full 5 gallons.
Made a 1.065 starter (1.2 L of water and 7.5 oz of DME) and pitched a vial of WLP099 (super high-gravity). Went through standard starter procedure. Poured off most after chilling and pitched the rest at room temp.
Down to 30 in a week at room temp! Hoping for more...
Down to 25 after 2 weeks, which is the listed terminal but I'm going to give it another week.
Down to 22 after 3 weeks. Stopped, as I didn't want it to be too dry.
Into bottling bucket, then added ?? corn sugar and bottled into 12 and 22 oz bottles
