How to make nettle beer
Writer and wild brewer Pascal Baudar shares his recipe for making nettle beer.

I sometimes enjoy going back to my Celtic roots and making some medicinal herbal beer. Aside from making a somewhat pleasant drink, stinging nettles Urtica dioica are a great source of vitamin C and apparently help alleviate rheumatic pain.
It’s a Belgian dream – a beer with a lot of health benefits. Different brewers use different methods for this recipe. What follows is what I do.

Take care
As the name suggests, stinging nettles can sting and cause swelling and itchy skin! The stem and leaves have tiny barbs to protect the plant. These contain a mix of formic acid, histamine, acetycholine and serotonin. Wear gloves when picking and handling them.

Ingredients
- Nettles 454-860g, fresh
- Water 3.78 litres
- Brown sugar 340-567g, or molasses
- Ginger root 14g, finely cut or grated
- Lemons 3
- Dandelion leaves 56g, optional
- Cream of tartar 28g
- Yeast beer yeast or wild yeast
Method

Step 1
Bring the water to a boil and add the cleaned nettles. Boil for 20 to 30 minutes, then add the brown sugar, ginger, lemons (juice them first, then throw them in the brew as well), dandelion leaves (if using), and cream of tartar. Boil for another 5 minutes.

Step 2
Remove the pot from the heat and place it (with the lid on) in your sink filled with cold water. Change the cold water in the sink two or three times until your beer is lukewarm (around 21°C).

Step 3
Strain into your fermenter (bottle, pot, or whatever you’re using), add the yeast (wild or commercial), and place an airlock (or clean towel) on top.

Step 4
Ferment for 3 to 4 days for 340g sugar or 7 to 8 days for 567g sugar (counting from when the fermentation is active, usually 8 to 12 hours after adding the yeast), then bottle. I don’t use any priming sugar.
The fermentation is quite active after bottling so I like to use a recycled plastic soda bottle to monitor for any excess carbonation and release it if necessary by opening the top slowly.
Most people drink nettle beer young, after a week or so; it’s not meant to be aged, as the flavors will be altered, and not in a good way.
