WLP001 - your basic cali common yeast used by many brewers as a default yeast. What did I learn when I went? It was terrible! They lined up WLP001 against 3 other alternative strains and WLP001 easily ranked last. I realized I was *wasting* my beer with this yeast.
This place is a MUST for EVERY brewer that lives or visits SD. Taste the same beer fermented with 4 radically different yeasts results in 4 totally different beers.

Also, you can buy anything from their catalog including every yeast they produce. They're never out of stock. Costs no more than lhbs. Support your lhbs for sure, but if you're inspired by a particular yeast you tasted, you can get it before you leave and not worry about your lhbs having it in stock.
