Earthhop Gruit Ale

greater burdock (Arctium lappa)

Jordhumle is an old-time Scandinavian name for yarrow (Achillea millefolium) meaning earth hops. This is a play on the plant’s historical use as a bittering and preservative agent in ales commonly used in communities until the 18th century, when bitter resin in the unripe female flowers of hops (Humuls lupulus) became the preferred ingredient of choice. It’s also a term, among many that are no longer in common use, that can describe any herbs that were used as a substitute for hops up until the point that hops was legislated in as the only legal herbal preservative in beer.

Anyhow, I found this old nickname extremely appropriate to describe my newest gruit style ale, which features the bitter, resinous scented flowering tops of yarrow and the deep, woodsy aromatic and bitter-sweet tasting roots of burock (Arctium lappa). Burdock, the plant that graciously supplies us with burs to get caught in our clothes, bears a 1-3+ foot long taproot which has long been used as an ingredient in strengthening, blood purifying tonic beers taken in the spring to cleanse the body from a monotonous winter diet lacking in fresh fruits and vegetables. The roots, rich in iron, calcium and other minerals, can also be used to improve the function of the liver and revive a sluggish digestive system by stimulating digestion before and after a meal.

Yarrow was an even more popular ingredient in centuries old beer recipes, being added for it’s potent anti-inflammatory and anti-bacterial properties.  The leaves and flowering tops can be used medicinally to prevent headaches, clear sinus congestion, sooth sore throats, quell aching teeth, relieve thirst, improve digestion, prevent heavy and painful menstruation, fight viral and bacterial infections, stimulate the recovery of injuries, stop heavy bleeding, disinfect wounds and assist with countless other maladies. The inclusion of yarrow in a recipe was also believed to make the resulting beer more intoxicating, much the same as Labrador-tea (Ledum groenlandicum and spp.) which has narcotic-like effects when taken in large enough doses.

Dried yarrow flowers and fresh burdock root

I have been wanting to use both of these herbs in a recipe for a long time. I am sure that they could both be featured in their own individual recipes to extenuate their own unique personalities, and that is most definitely going to happen at some point. I am hoping that this recipe will create a slightly bitter ale with a deep aroma of damp moss and rotting logs complimented with a balanced resinous, woodsy and floral flavour.

INGREDIENTS

5 gallons water
3 litres liquid amber barley malt extract
6 ounces fresh or 3 ounces dried burdock root, coarsely sliced.
1 ounce recently dried flowering tops of yarrow
20 grams Cascade hops
1 powered Irish moss tablet (helps with clarity)
15 grams de-bittered ale yeast

INSTRUCTIONS

1. Bring either 1 or 1-5 gallons of water to a boil. Make sure that the pot is only around 50% full in order to accommodate the addition of the next few ingredients.

2. Carefully add the liquid amber barely malt extract to the water. This is going to be an annoying, sticky mess no matter what but be advised to take some precautions. Stir while adding the malt so it doesn’t burn at the bottom of the pan. Try to get as much of it out of the containers as possible. It might even be worth while to remove the pot from the heat until all of the malt is in there and dissolved evenly.

3. Bring the water back up to a boil and add the sliced burdock root chunks and yarrow flowers. The yarrow can be added whole because it limps up quite a bit. Set timer for 30 minutes.

4. Reduce the heat to a simmer and cook the herbs and the malt for 15 minutes. Stir occasionally, as the herbs like to float.

5. Once 15 minutes has passed, add the Irish moss tablet and the 20 grams of Cascade hops, sprinkling them slowly into the wort. Stir until the Irish tablet completely dissolves, about 2 or 3 minutes. Hops has a tendency to make the brew foam like crazy, so keep stirring and turning down the heat until you have a consistent simmer. If you full on boil it, the wort is going to throw up all over your stove. Whenever you are not stirring, you can have the lid on the pot to retain heat but with a slight crack. Also, don’t leave the room after the hops is in there. Keep an eye on it for the first 5 minutes especially once it goes in.

6. Once 30 minutes has passed, turn off the heat. Remove the now finished wort into a location where it can sit and cool down, with the lid covering it. I stick in a thermometer to monitor the temperature as it cools. You want the wort down to at least 100 °F (optimally 70-75 °F) before you proceed with the next step.

If your beer looks like soup, you’re doing it right.

7. Using something like potassium metabisulphite or Diversol, sanitize a carboy or fermenting bucket, funnel, strainer and airlock (make sure that it is fitted to your fermenter).

8. Strain and pour the wort through a funnel into your fermenter. Top up the carboy with water until a total of 4 gallons is reached. I wrote in with a permanent marker the measurements on the outside of my glass carboy, which makes this easy. I suggest you do that too, on whatever you are fermenting in for future reference.

8. Pitch in the 30 grams of de-bittered ale yeast (It is a good idea to let it sit out the night before so it is room temperature when you add it) into your fermenter with a funnel and insert the airlock. Done. Now clean up the huge mess you’ve made and wait 5-7 days until fermentation is complete.
