I’ve only ever brewed ales as I do not have anywhere that remains at a consistently cool temperature enough to brew a lager or pils. I have a shed and also a fridge big enough to lager the beer once fermentation has taken place – it’s just that initial couple of weeks that’s the problem.
The spot I usually use to ferment beer stays at a consistent 21-22° all year round. I’d rather it was a little cooler but the beer turns out fine. I believe a constant temperature is key.
I’ve found another spot in the house that seems to be about 18° which is still too warm for an authentic pils, but I thought I’d give it a go regardless.
I’m using SAFLAGER S-23 which, according to the Fermentis website, the fermentation temp should be between 9-22°C and ideally 12-15°C. So although my 18° is above the ‘ideal’ range, it still sits easily within the tolerable range for this strain.
Regardless, I’m sure I’ll end up with a tasty beer, but it will be interesting to see how the slightly higher fermentation temp affects the authenticity of the pilsner. I’m expecting a less crisp beer with a few fruity, ale-like esters.
Once brewed, I will crash cool for a week in a secondary and then rack into a corny keg and lager it in under pressure in the fridge for four weeks
