Many of the Vault strains are periodically released as seasonal strains. However, I have never seen WLP033 released as a seasonal. The only way to obtain WLP033 is to pre-order it and hope that the count gets close enough to the pre-order propagation count of 150. I remember the last time that White Labs propagated. If I recall correctly, I placed my pre-order in 2015 and White Labs did not propagate it until 2017 when I was on a brewing hiatus. If we are going to reach the propagation pre-order count any time in the near future, we are going to need to promote this culture in a big way, maybe via a virtual "big brew." It works best with beers around 1.052 or smaller. I would not call WLP033 an AIPA or APA yeast. For those looking for a squeaky-clean American ale fermentation profile, WLP033 is not your yeast culture.
