The ATF Czech Dark Lager is a rich malty beer with smooth coffee and chocolate aromas that blend beautifully with the earthy, herbal, and floral notes of the Saaz hops.
The flavour profile is a captivating blend of rich bready malt, roast coffee and chocolate, dark caramel, and dark fruit tones balanced by a smooth bitterness. Clean and crisp with a slightly creamy mouthfeel, the ATF Czech Dark Lager is a moreish beer.
Yeast is not included in the kit. If fermenting cold we recommend using Froth Vagabond (Assumed Origin: Budêjovický Budvar) or:
If fermenting warm we recommend using Fermentis SafLager W-34/70 or Mangrove Jack’s Californian Lager.
Fermentis SafLager W-34/70
Sensory testing performed by Fermentis on W-34/70 shows that it is a very robust yeast capable of providing a clean neutral flavour profile across a wide range of fermentation temperatures (12℃ - 20℃). Click here to download the Fermentis iPhone app for more information.
Note on Water Profile
The recommended water profile for this beer is very soft with no more than 7ppm of any mineral. The following water sources have slightly higher concentrations of some minerals than the recommended water profile, however they are still sufficiently soft to produce a soft delicate beer such as the ATF Bohemian Pilsner:
The beer may be brewed using other water sources, but may not have the same soft delicate mouthfeel and bitterness. Rainwater, reverse osmosis water, or bottled spring water is ideal.
