Using Wyeast 2112 Cal Lager. Usually, from my experience, Wyeast takes a couple hours to swell. This didn't do anything for a whole day or more. Finally, after 2 days I'd say its half swollen, maybe a little more. It was shipped in over 100 degree weather and I didn't refrigerate it for a few days after it came in b/c my g/f put the box away and didn't to tell me it came in (but that's besides the point). Is this safe to use or should I tell the company to send me more?
