So made a yeast starter with some London Ale Yeast on wednesday around 7pm at night PST. Has yeast nutrient and 3/4 cup of DME in about 1200ml of water that was boiled with the DME for 15 minutes and then cooled to 80 degrees, aerated and yeast pitched.
Yeast was plenty viable...think the date on the bottle was sometime in april and my LHBS ALWAYS has fresh stuff.
Ive done plenty of yeast starters before and 2 days prior was always plenty of time for the starter to do its thing, cold crash the night before brew, and then pour off the top layer of liquid leaving you that nice yeast cake at the bottom.
Problem is it hasnt taken off yet, at least visibly, and ive been swirling the flask multiple times daily and its sitting at about 76 degrees as i never really have done extreme temperature control on my yeast starters as they were never above 80. The yeast settles like its fat and happy but i dont really see anything going on and im somewhat afraid to take a SG reading because i dont have much liquid in there to take a sample with. Also i didnt take a OG, never really thought i had to for a starter.
My goal is to brew tomorrow should i grab another from the LHBS before they close or should i just try pitching the whole flask and see if that takes off with the brew i am going to make tomorrow? Or i could cold crash it tonight and see how the yeast does anything within the first 12 hours?
