Starks – Dunkles Bock


Dunkels Bock – 35.5 Point Score
Brewed by Bill Becker of Headrick, Oklahoma

Best of Show at the 2016 German Fest Stein Challenge

Brewers background: “I have been brewing for over 10 years now and competing for about 8 years. I got into home brewing from a co-worker, he was stationed in Saudi Arabia for work which is a Dry country. So they had to take matters into their own hands, needless to say he explained how it was done and I was intrigued. So like most people I started with an extract kit and have been hooked ever since.”

Brewing System: “Currently I use a two vessel system, an insulated SS Brew Tech mash tun and an SS Brew Tech boil kettle. All of my beers are created using the no-sparge method, I recently added a single pump to help out.”

Homebrew Club: “Southwest Oklahoma Brewers Association or SOBA.”

Advice you would give to new competition brewers? “If you are brewing a Lager, be sure to slowly ramp the fermentation temperature down to lagering temp. Don’t crash it.”

Mash Process

Single infusion mash with mash out. 155F for 60 minutes, 168F for 15 mintues. My efficiency was 68% for this beer. I use a NO sparge method which is lower efficiency though produces a great malt flavor.

Fermentation Process

Fermented at 50F for 7 days, ramp temperature up 2 degrees per day until 60F, ramp temperature down 2 degrees per day to lagering temp of 33F. Lagered for 8 weeks.

Additional Notes

Created a 2 liter starter.

RO Water Treated with 1/4 TSP 10% Phosphoric Acid per 5 gallons

1 TSP CACI2 in MASH (Thanks for the water tips Mr. Strong!)
