FWIW, I used the berliner weisse yeast last time it came out as a VSS. Ended up a nice beer, but not what I would call a berliner weisse. Very lemony-zesty flavours, along with the bret, and it took 6 months to finish. Took 4 days before primary started (1030 OG), fermented down to 1010 in around 8 days. Racked to secondary, and it formed a pellicle over the top, and stayed that way for the next 6 months, slowly dropping the SG. Finished at 1.000, so it is over 4%. Noticeable bret character, little to no lacto (and IMO lacto is the hallmark of a berliner).
It makes a very drinkable, low-level funky beer, I will use it again, but next time I go to make a berliner, I will pitch a lacto packet for a few days before I pitch a german ale yeast. Again, not unhappy with the beer it produced, I am not convinced it is a berliner strain.
All the best
