Thanks. Yep, I went with lager to take advantage of the cool weather. I don't have a temp controller yet, but I do have a temp monitor and remote temp sensor and sensor bulb. I'm fermenting in the coolest room. It is on the NE corner of the house, away from afternoon sun, with shaded window. Frozen half liter water bottles against the carboy, all covered with a heavy blanket keep it cool. I'm brewing a classic pilsner today and then an ale when the primary is available again. Any special tips for making pilsner?
