How To Brew International Dark Lager: Robust and Roasty World of Dark Lager Beers

International Dark Lager is the dark version of the International Pale Lagers often brewed by large, industrial breweries. These dark lagers were brewed to appeal to a broad audience. It is a sweeter version of the International Pale Lager with some more body and favor, but equally restrained bitterness.

There are some styles that are similar to International Dark Lagers. These styles include: Munich Dunkel, Schwarzbier, and other dark lagers.

However, there is less flavor and richness in the International Dark Lagers than the beer styles I listed above.

Usually, adjuncts are used, as with the International Pale Lager.

Perception

Dark beers, especially Stouts and Porters, have always received a bad rap. Oftentimes novice beer drinkers think of such beers as heavy and too roasty.

I am sure this same perception would carry over to International Dark Lagers as well. However, that perception is totally inaccurate.

Don’t Be Afraid of the Dark

Many larger breweries will use a natural beer coloring called Sinamar. This was first introduced by Weyermann Company in Germany in 1902. It is a natural coloring derived from debittered Carafa Special II.

It allows for a beer to turn dark without the worry of a roast character. Use one fluid ounce in five gallons, while cooling, to add 5 SMR of color.

To make a pale golden beer dark brown or black, add 3 to 4 ounces of Sinamar to 5 gallons.

Tips for Brewing your own International Dark Lagers 

Grain

Much like the grain bill for the International Dark Lager, it is pretty basic. Since it is a lager, a good quality Pilsner malt is where you want to start off.

However, not all lagers need to start off with Pilsner malt. There was some conflicting information that I discovered while researching the style. Some suggest 2-Row or even 6-Row being used as a base malt.

Vienna malt can be added for a little bit of color and malt interest. For the color, Carafa Special II can be used. Since you do not want to impart much roastiness or chocolate notes to this beer, brewers should not use roasted barley or chocolate malt.

Instead Carafa Special II can give you the color that you want to achieve that SRM level of 14-22 without the roast or chocolate notes.

Hops

The hops really do not shine or standout with this style. Honestly, any hop you have on hand will do. Keeping your IBUs anywhere between 8 and 20 will suit you just fine.

Something such as Hallertauer, Saaz, Tettnang, or Northern Brewer will be the hop choice for this beer. Just make sure you are checking the IBUs with the one hop addition at 60 minutes.

Yeast

A clean lager strain will be the yeast strain you should decide to use for this style of beer. WYeast 2007 Pilsen Lager, WYeast 2206 Bavarian Lager. White Labs 830 German Lager Yeast.

Fermentation:

Ferment at 50°F (10°C) or whatever your yeast manufacturer suggests until your final gravity is reached. It is a good idea to increase the temperature by about ten degrees at the end of fermentation to assist in diacetyl cleanup.

Once the beer completes fermentation and after the diacetyl rest, you may want to cold crash it to 35°F (2°C) for about 4 weeks to improve clarity.
