Thanks for all of the info! I'll bookmark those sites for reference. It has been refrigerated since the day it was activated.
I actually have yet to make a starter since I have been brewing. So I guess I'm a bit confused about this yeast requiring a starter, and not being adequate for 5 gallon batches. So far I haven't had any fermenting issues, maybe just getting lucky? (The last brew with this type of yeast went from 1.052 to 1.011)
Just to make sure we're referring to the same yeast, this is what I'm using:
"The Activator™ is designed to directly inoculate 5 gallons of standard strength ale wort (1.034-1.060 SG) with professional pitching rates. "
I'm more than happy to create a starter with it, just want to make sure it really is needed.
