Doppelbock is one of the most difficult and time consuming infusions Glengarry creates. The infusion process takes about 4 hours to do correctly. This beer, like the Vanilla Bean Porter, has a very high grain load for the infusion and stresses the Glengarry Brewery infrastructure. The infusion requires both tanks to be used and involves frequent transfers back and forth for the process to succeed and produce the smoky sweet character of a Dopple. The labor is well worth the effort. Lagering can last for up to 12 weeks to achieve the correct flavor crispness. The dark lager that emerges is bold and crisp, yet sweet like a Dopplebock should be.
This beer, and most Glengarry Brewing beers, are true to the "Reinheitsgebot". This means the ingredients are restrained to the categories of Grains, Hops, and Yeast. No fruit or other adjuncts (tongue in cheek). Here is a list of Glengarry Dopplebock ingredients.
A good Dopplebock features the malt.
Dopplebock features the malt, not the hops. So you won't taste a whole lot of hop in this beer. It is brewed to be crisp and bold (lengthy lagering process), yet sweet and malty.
