I know, I know, RDWHAHB, but . . .
Tomorrow, I plan on brewing for the first time with a liquid yeast (White Labs Southern German Lager). I got up this morning and boiled 3 oz of DME in 700cc water with a small amount (1/8 tsp) yeast nutrient. I cooled it to 78 F, and pitched the yeast which had been in the fridge for 2-3 weeks after allowing it to come to room temp overnight. I covered it with a piece of sanitized aluminum foil.
Six hours or so later there were no definite signs of fermentation. No bubbles, no krausen, nothing. I put on an airlock so I could see if there was any gas production, but so far, nothing - nada - zilch. There is a pretty substantial amount of sediment on the bottom of the flask - maybe more than the 1/2 tube slurry I started with, but I can't be certain.
I will watch it overnight, but if everything is the same in the morning, do I trust it or not? I could order more yeast - maybe a different kind - and brew next weekend.
