Hi
Been making Swarzbiers now for some time (i might have been the first in oz) and won many awards with this style. There are a few things you need to do to make a good Swarzbier and is a lot of patience.
If you look at the guidlines of the style you will see that its a black lager and it should not be TOO black.
Its a dark Pilsener is the way i describe the beer.
The grain bill and the Yeast is the secret. Never use any roasted barley or roasted malts.
The best way to get the colour right is a little carafa from Weyermans and 5% of carapils with the rest a good Pilsener malt.
Use the same bitterness as a good Pilsener and you will get it right.
Ferment with a dry clean lager yeast not a malty lager yeast as you dont want this beer to be malty.
Ferment at 10 - 12C for 3 weeks.
Rest at 20C for 4 days and then rack to a glass fermenter and lager for 6 weeks.
I had a Swarzbier on tap at Big brew day at my place this month and it was ok but could have been better. I used WL's San fran Lager and only lagered for 2 weeks. It was too young but had no complaints.
Cheers
