Milled: Yes
Yeast: Dry

Imperial Stout is the beer of Russian Czars, much loved and enjoyed by “Catherine II, Empress of all the Russias” back in the late 18th century.  British Brewers were exporting this beer from England to the Russian Imperial Court and around the Baltic states 200 years ago!  Big, Bold and Dark, Imperial Stout is a beer style that has captured craft and homebrewers attention over the past 20 years.  Not for the faint of heart, it is a style that needs to be sipped and savoured in the depth of a cold dark winter by a warm fire or alongside a rich decadent dessert deserving of todays modern Czars.  If it was good enough for Catherine II, aka "Czarina Catherine the Great", and her court in the Baltic States then its good enough for us. So, what are you waiting for?

ваше здоровье! Cheers #brewhappy #drinkhappier #enjoyresponsibly

      1. Adjust your brewing water with calcium chloride to reach 2:1 chloride to sulfate ratio.
      2. Mill the grains and dough-in targeting a mash thickness that will enable your system to achieve the necessary pre-boil volume and gravity.  Around 3 Litres of water to 1 Kg of grain (a liquor-to-grist ratio of about 3:1 by weight or around 33 Litres).
      3. Hold the mash at 68°C (154°F) until enzymatic conversion is complete (60 mins).
      4. Infuse the mash with near boiling water while stirring or with a recirculating mash system raise the temperature to mash out at 76 °C (168 °F). Sparge slowly with 77 °C (170 °F) water, collecting wort until the pre-boil kettle volume is around 25 L (6.5 gal).
      5. Add 100g of Challenger UK Hops at start of vigorous 60 minute boil. The total boil time will be 60 minutes.
      6. Add 100g of Willamette US Hop Pellets 10 minutes from the end of boil. Optional extras: add Deltafloc tablet or 1 tsp of Irish Moss and Servomyces Yeast Nutrient with 10 mins of boil remaining.
      7. Cool wort and transfer to the primary fermenter oxygenating wort and pitching Liquid Yeast or Lallemand Brewing Nottingham Ale yeast at 19° C.
      8. Ferment at 19 °C until the yeast drops clear. Allow the lees to settle and the brew to mature without pressure for another two days after fermentation appears finished. Rack to a keg and force carbonate or rack to a bottling bucket, add priming sugar and bottle. Target a carbonation level of 2 to 2.5 volumes.
      9. Store the beer in a cool, dark place and allow to age. The beer will improve over time and should mature six or more months before drinking.
      10. Food compliments - rich dark chocolate puddings, heavy meat dishes e.g. Steak, Hungarian Goulash, Pies and Beef and Lamb Roast.
