So now having used both packs of this yeast I had, I can make a better call on what I think of it. I've found some pros and cons with it. As far as attenuation, it sucks pretty bad. I tried with a pilsner and an amber lager both brewed a week apart. The pilsner was an Imperial which I expected to clock in at 7.5%, I split the batch and hit target gravity 1.008 without problem using the WLP815, the Mauri yeast finished at 1.018 and made the beer so sweet it was disgusting. So I'm leaving it to bottle age with hopes it dries out more in the bottle.
Second batch one week later Sept 27th, the amber lager had and OG of 1.050 and it only finished at 1.012 and that was tested today right before I kegged it, however beer does taste good. And the pro I have found with the yeast is how well it cleans up after itself. Both recipes had pilsner malt, both batches dropped out completely clear without any agents, just secondary in my basement. I don't think I would make a point to ever buy it though.
