I fermented a 1 gallon SMaSH with pils malt / saaz hops. Split the fermentation, one with 34/70 lager yeast and one with us-05 ale yeast. People say this is a hard style to brew since the clean flavour highlights any mistakes - that was certainly my experience, though after enough time it was very enjoyable and the off-flavours had mellowed a lot.
The ale I didn't bother with temperature control but ambient temps were cool. My best guess is that it mostly fermented at under 65f.
Since it was such a small test batch I only got 3 bottles of ale + 7 lager. The first early ale bottle tasted real average. Last bottle after about 2 months lagering tasted excellent, just a bit of lingering DMS.
I would have no hesitation brewing this again with us-05 ale yeast, at temperature controlled low 60s. I did prefer the lager version but the ale version was good too.
