You will also need

Yeast: Dry lager yeast, such as W-34/70: three 11.5 g (0.4 oz) packets. At a gravity this high, underpitching leaves off-flavors and a fermentation that won't finish.

Water: About 30.5 L (8.1 gal): 20 L (5.3 gal) for the mash and 10.5 L (2.8 gal) for the sparge.

Priming sugar: 5.0 g of white sugar per liter bottled (0.7 oz/gal): about 95 g (3.4 oz) for 19 L (5.0 gal). Lively carbonation, like a commercial lager.

Hops: pellets, kept in the freezer until brew day.

Step by step

  1. Heat 20 L (5.3 gal) of water to 72 °C (162 °F), add the crushed malt and stir until there are no lumps. It should settle at about 66 °C (151 °F): hold that temperature for 60 minutes, covered. This temperature leaves some body, which a beer this strong needs so it doesn't taste watery.
  2. Lift out the grain and sparge it with 10.5 L (2.8 gal) of water at 76 °C (169 °F). You should collect about 24 L (6.3 gal) of wort at 1.060.
  3. Bring to a boil and boil for 60 minutes, uncovered and vigorously: pilsner malt gives off a cooked-corn smell (DMS) that leaves with the steam. At the start of the boil, 17 g (0.6 oz) of Nugget. With 15 minutes left, 25 g (0.9 oz) of Sladek.
  4. Chill as fast as you can down to 10 °C (50 °F), transfer about 20 L (5.3 gal) to the sanitized fermenter and take a gravity reading: it should be around 1.072. Aerate well.
  5. Pitch the yeast and ferment at 10 °C (50 °F) for about two weeks. At the end, raise it to 16-18 °C (61-64 °F) for two or three days so the yeast can clean up the diacetyl (the buttery flavor).
  6. Once the gravity sits at 1.017 for three days in a row, drop the beer to 2-4 °C (36-39 °F) and leave it there for six weeks: that cold storage is the lagering, which leaves it clean and rounded. Without a fridge with a temperature controller, you're better off brewing an ale.
  7. Bottle with the priming sugar and let it carbonate for two weeks at 18-20 °C (64-68 °F) before chilling it again. Serve it very cold.

Hijos de Rivera calls it a Dunkel Bock, but at 90 EBC (46 SRM) it's far darker than the BJCP Dunkles Bock (6C) allows. That's why it's filed as a Commercial Specialty Beer (34A), the category for clones that don't fit any other style.

Hijos de Rivera publishes 7.2% ABV, 27 bitterness units, 90 EBC (46 SRM), four malts with different levels of roast, and Nugget and Sladek hops. Which malts and in what proportion, the yeast and the temperatures are a homebrew approximation, not the brewery's recipe.

Carafa Special III is dehusked: it gives the black color without the harsh bitterness of roasted barley. If you can't find it, use chocolate malt, knowing it will come out more roasty.

Sladek is Czech and hard to find: Saaz works, using 25 × 6 ÷ your Saaz's alpha acid percentage, in grams.

The style: Commercial Specialty Beer (BJCP 34A), with its history, its numbers and other ways to brew it.

Frequently asked questions

How strong will this 1906 Black Coupage Clone be?

About 7.2% ABV: it starts at 1.072 and finishes at 1.017, and (OG − FG) × 131.25 gives that percentage.

How long until it is ready?

One brew day, fermentation at 10 °C (50 °F) for 14 days and 6 weeks at 2-4 °C (36-39 °F) and about two weeks in the bottle: give it a little over a month.

Can I use a different bittering hop?

Yes. What matters is keeping the bitterness: if you use another hop instead of Nugget at 13.0% alpha acids, work out the grams from its alpha acids (or with the IBU calculator) to stay at about 27 IBUs.

What if my system does not get 72% efficiency?

Your gravity will come out different. Scale the base malt up or down (or add a little dry malt extract to the boil if you fall short) and recalculate the water with the calculator.
