Grandmaster Brewer
I brewed a Pilsner using Weyermanns floor malted Bohemian Pilsner malt. I did a step mash using the following recommended mash profile I got from the Weyermanns Web site which is similar to the BeerSmith BIAB pilsner step mash profile.
20 min 50?C (122?F)
40 min 63?C (145?F)
5 min 68?C (154?F)
20 min 72?C (162?F)
mash-out 76?C (169?F)
I made a two litre starter of WLP800 Urquell Pilsner yeast which took off after 6 days.
It has stalled at 1.020 and I cannot get it to shift. I've tried raising the temperature from 11C to 16C with no effect. It's been stalled now for two weeks. I'm thinking I may have a lot of unfermentable sugars caused by the mash profile.
A friend has experienced similar problems with this mash profile on more than one occasion.
Has anybody else experienced this?
