I brewed a 1 1/2 gal stock pot of wort. Transferred it into a 5 gal glass carboy with 3 1/2 gal clean water. Cooled in the snow down to 72F. OG=1.090 - I pitched the entire vial of WLP001 California Ale Yeast (liquid) - without making a starter - had not read directions prior to pitching or brewing. Attached blowoff. At about six hours after pitching I went and vigorously shook the carboy. Its now 36 hours after pitching and there is absolutely no activity - there is some suspended sediment. Question is whether I should give this more time to start fermentation- or whether its a lost cause- or if there is something I can do to restart this batch? This was my first attempt with a liquid yeast as I have only used dry yeasts in the past. I'm assuming at this point I will get some off flavors, but I just don't want to have to dump it down the drain. Thank you in advance!
