With the release of Java 8 coming soon it seemed like a good time to begin to prepare for the celebrations. In consultation with Duke himself, the following recipe was arrived at and has been brewed. The beer style is hybrid being brewed like a California Common Beer (an ale) but with a Pilsner grain and hops bill.
Duke's Choice Virtual Pilsner
2.5kg / 5.5lb Canadian 2-row barley malt (Rahr Malting)
1.1kg / 2.5lb Pilsen dry malt extract + 60g/2oz for yeast starter
50g / 1.75oz Hallertau hops (4.5 Alpha)
White Labs WLP080 Cream Ale or Wyeast 2112 California Lager
Create a 800ml yeast starter with 60g/2oz yeast Pilsner dry malt extract at least
6 hours ahead.
7.5 liter/2 gallon mash of barley @ 65C/150F for 45 minutes.
Sparge with 7.5 liters/2 gallons 77C/170F water.
Bring to a boil for 60 minutes
At hot break add 28g/1.0oz of hops
At 30 minutes add 15/g/0.5oz of hops
At 45 minutes add Irish moss tablet (Whirlfloc) and 2.5ml/ 1/2tsp yeast nutrition
At flame out add 7g/0.25oz of hops
Cool to 25C/80F as quickly as possible. Rack and oxygenate to carboy with minimal
boil sludge, and top off to 21 liters/5.5 gallons in 25liter/6.5 gallon
Pitch yeast and add an airlock. Ferment at 15-17C / 59-63F
After 2 or 3 weeks rack to 19 liters/5 gallon secondary with minimal headspace.
Add airlock. Refrigerate for 1 week.
Rack to keg, purge oxygen and refrigerate for 48-72 hours before carbonation to
30psi. Or bottle and age for at least two weeks.
