Taste Notes

This was really good. Esters were not a problem at all. Toasty, bready malt, dry and bitter, with fantastic medium floral & spicy noble hop character.

Notes

1.3 L starter with 4.4 oz DME. Pitching @1.5 million cells/mL/° Plato. Hopefully it can handle fermenting at ~68°F with a big pitch and not throw too many esters. Add black malt last 15 min of mash. First infusion with 0.94 g gypsum, 0.94 g CaCl2, and 1.55 g Epsom salt Second infusion with 0.2 g gypsum, 0.2 g CaCl2, and 0.35 g epsom salt. Mash out infusion with 0.37 g gypsum, 0.37 g CaCl2, and 0.6 g epsom salt. Sparge with 0.9 g gypsum, 0.9 g CaCl2, 1.5 g epsom salt, 0.8 mL lactic acid per batch. (Ca ppm): 92 (Mg ppm): 21 (Na ppm): 22 (Cl ppm): 77 (SO4 ppm):130 Ratio: 0.54 Ferment in keg @60°F until FG is reached. Then move to ambient for 2 day diacetyl rest. Cold crash. Pressure transfer to keg with clear beer draft system, gelatin, and campden tablet. Burst carb @30 psi for 24 h and reduce pressure to 14 psi. 7/8: made yeast starter. Reused yeast from American Lager (34/70). 7/9: mash temps of 148°F/153°F/161°F. Boiled a bit hard. Cut boil short and added 10 min hops 17 min early. Still overboiled a touch. 4.9 gal, 1.050. Let starter keep going overnight - still has a sizeable krausen. 7/10: put starter into fridge to decant. 7/11: pitched yeast in am. Wort is 60°F. 7/15: increased ferm SP temp to 62°F. Wasn't maintaining temp as well so assumed less activity. 7/18: 1.012. removed from fridge for diacetyl rest. 7/22: 1.009. No diacetyl (from what I can tell). Placed in fridge to cold crash in pm. 7/24: kegged with campden tablet, gelatin, and clear beer draft system. Tastes surprisingly sweet but wasn't completely clear when sampling. Hopefully it dries out and is more bitter as it clarifies.
