Bohemian Pilsner

Pitched this onto the yeast cake of the previous pilsner. Managed to chill the wort down to 12.5°C by pumping ice water through the immersion chiller. Due to pitching on yeast cake there was a very short lag time – obvious fermentation activity within 12 hours (at 12°C).

Result was just ok – tasted fine, slightly sweet/malty, not much bitterness and despite an extended lagering period quite a lot of sediment ended up in the bottles resulting in a cloudy appearance.

  1. Nice recipe. How did you keep your fermenter at 12oC?

    (I’m lucky to live in a cold climate so for a winter brew this is easy for me.)

    1. Hi Steve,
      I have a dedicated fridge for brewing and a STC1000 temp controller to keep it in the desired range. If you have an old fridge or can pick up an old fridge for brewing it’s well worth also getting a STC1000 so you can precisely control the temps. I also use it for controlling heating in winter when I need to raise the temp, I just plug in a hairdryer on the heating output – a hairdryer is an ideal heater for a fridge. You can pick up STC1000 controllers for really cheap on ebay.
      Cheers,
      Aidan
