Hey guys, I'm brewing up the Sam Smith Taddy Porter clone from Austin soon. I've been brewing for awhile, but never used liquid yeast. Do I need a starter or just follow the instructions listed on the yeast?
You need a starter my friend.
take a look at this calculator: Mrmalty.com
Honestly i would just use the one vial without a starter. However, ideally you may need to have a higher number of yeast cells to achieve the "optimum" performance .
A starter assures that your White labs yeast is active to begin with, and it also gives you enough yeast to get the job done.
Make a starter. *Not* making a starter never results in a better beer.
Three Really good reasons for starters
Improves Yeast Health
Raises numbers to appropriated level
The numbers of yeast and the health are the key features that will improve your beer and make you never doubt doing starters again.
