He's got a heck of a lot more than 8 batches there. When I make my starters I use about 1/2 to 1 tsp of yeast out of my washed jars to make a 1.5L starter 24-36 hours before brew time. Fermentations take of in 8-10 hours on average.
3 jars of WLP001
3 jars of WLP002
3 jars of WLP005
3 jars of WLP008
3 jars of WLP320
Enough to last a long time. To use, I take about 1/2 tsp from the jar and make a starter 24-36 hours before brew time.
I'd say go for it.
I brewed a Russian Imperial Stout using that yeast at the recommendation of my LHBS. It took 4th at the San Diego Fair Homebrew competition last weekend.
Congratulations!
I too was there. Got 4th in the Stout category with a Russian Imperial Stout. It was the second beer I made.
Going to have to make another batch of it this weekend.
