This month’s recipe for a Doppelbock provides an example of doing just that. Toffee flavours in a Doppelbock are not traditional, but my goodness are they delightful. We have to give Hells Basement credit for having this vision as they incorporated one of our first batches of brown malt (caribou malt) into their award winning Doppelbock years ago.

- Pitch Biergarten yeast at a temperature of 8°C.
- Ferment at a temperature of 10°C.
- Perform a diacetyl rest, by increasing the temperature 1°C/per day once the gravity of the beer reaches 6°P and hold at 15°C until the final gravity is consistent for 3 days.
- Cold crash beer to 0°C and lager for 4-6 weeks.
- Dump yeast.
- Once fermentation is complete, proceed to canning, bottling or kegging.
