Fermentation Profile: 14C for 2 days, 10C for 7 days. Then second staged to a corny keg. Increase 3C roughly every 12 hours until you get up to 20C. Leave at 20C for 2-3 days, do a gravity reading to ensure fermentation is complete before ramping down the temp 3C every 12 hours until it reaches 0-1C. Leave for 3 days before gassing/drinking. This is based on the speed lagering methods as discussed on the Brulosophy Blog.
1 pack of dry W-34/70 to 100g of DME to 1.2 litres of water (preboil). 15-20C for 12-18 hours, 3C for for 6-10 hours.
Review Added 11.4.17 - So this is the first time I used the 'speed lagering' process and I must say I'm very happy with it. I 2nd staged and did the temperature ramp up/ramp down in a sealed corny keg (no airlock). The stuff was ready to gassed and drinkable right and the end of the temperature ramp down. For this recipe I originally planned to use Saaz hops but stuffed up, turned out I didn't have any (must have got drunk again and not updated my stock list), hence the use of Hersbrucker & Halleratau in this 'Bohemian' Pilsner. The end result was a delicous varient on a traditional recipe, came out a little creamy, I served the keg at a work party to rave reviews.
