Notes

Brewday using KM's Bulldog Brewer

Friday 9th November 2018

Mashed in at 66C with 22L. Mash pH at end of mash = 5.25. Sparged with about 8L of 55C water. Boiled for about an hour

OG = 1.062, pH = 5.16. Cooled to 20C and pitched 800 mL of a gen 1 WY1318 starter (pH = 3.8-3.9ish and tasted clean)

Wed 21st Nov - FG = 1.018, pH = 4.37. Kegged using CO2 transfer. 5.9% ABV

Initial tasting notes - too sour, too roast / acrid... hope it mellows out. Maybe worth a pastry addition too fatten it up / take off the edge

It might just be the roast character, but feels thin, needs more body, creaminess
