This is an expression of an Oktoberfest lager that relies on First Wort (FW) and All-Late hopping for its bitterness. Dark grains and Hallertau hops were added to the last decoction. The remainder were added as flavor or aroma hops. This decoction method is known as the Hochkutrz double decoction mash.

Original Gravity: 1.077The original gravity was well above the predicted. The boil was longer than expected, as the laudering continued to nearly 8.5 gallons. The total boil time was nearly 80m.
Fermentation:Pitched yeast on 13 August. The fermentation temperature is set at 53 degrees, but will increase as the wort heats up. I expect primary fermentation to take about three weeks.
