Taste Notes
36 hr - 153F, 1.084; slight acid/sulphur in nose; reminds of molasses in taste (maillard precursor?); gentle coffee character
wed 10 am (84 hr) - 154F, 1.070; sour smell, no sulphur detected, molasses subsided, but very sweet and thick; taking on a red hue; perhaps kick it up a degree in a few days
fri 10 am (132 hr) - 153-154F, 1.060; orange-tan krausen; stronger sulphur; dark fruit, caramel, (melanoidins?) in the nose; thinner in body today, but still insanely sweet; less molasses character; coming along nicely; absolutely no alcohol evident; slight acid in nose
dec 11, re-starter: wlp830, 2qt tap water, pH 6.1, 250mg lme, og 1.050, 60F, ? days, 50% duty cycle
sun 11 am (~156 hr) - 153F, 1.054, hmm (stuck?) notes above hold with slight alcohol and burnt astringency (not harsh at all though)
sat 9 am, 153F, 1.041; swirled up the yeast, still fermenting, patience!; smells bready, followed by yeasty, then dark fruit, slight booze; acid and almost belgian candy syrup (dark) in aroma; still very sweet and almost no alcohol, wow; lots of very interesting malt and dark sugar flavors; very clean ferment; no sulphur . patience
sun 3:30 pm, 154F, 1.034; swirled yeast, still bubbling. smells sweet, but tart, almost of cherries; then comes complex sugars and fruit in aroma; biscuit; very cloying to taste still, but finishes just warm enough with strong toasty/molasses character. patience

dec 11, 4:30pm, re-starter to transfer on to:
starter: wlp830, 2qt tap water, pH 6.1, 250mg lme, og 1.050, 60F, ? days, 50% duty cycle
2days later, no drop in gravity, but decanted and repitched 3qt of same composition starter (hoping reserves are building up)
This starter really took off after a few days; transferred doppel to kegs on dec 19 and pitched ~1qt per keg of starter at high activity.
dec 20, 1.030; 55F; despite my best efforts, this thing seems stuck; suspect combination of low-alcohol tolerance augustiner lager yeast, and potentially high mash temps (or the effect of triple decoction? -- aim for lower sac rest temp next time?); started crashing and carbonating; dropping 2-3deg F per day to 32F, planning to lager 6weeksNotes

Third decoction (thin):
wait 30 min

Authentic Germany mash schedule. Attempt to draw decoction from the thickest portion of the mash. Some sources recommend that each decoction amount be given a 15 minute saccharification rest at 158 F (70 C) before boiling it.
I swirled the yeast cake up after ~6 days to prevent stuck fermentationThis Recipe Has Not Been Rated
