The Wildcrafting Brewer

The art of brewing doesn’t stop at the usual ingredients: barley, hops, yeast and water. In fact, the origins of brewing involve a galaxy of wild and cultivated plants, fruits, berries, and other natural materials, which were once used to make a whole spectrum of creative fermented drinks.

In The Wildcrafting Brewer, Wild-plant expert and forager Pascal Baudar reveals the underlying philosophy and the practical techniques for making delicious concoctions, from simple wild sodas, to non-grape-based ‘country wines’, to primitive herbal beers, meads and traditional ethnic ferments.

The Wild Flavors of Belgium

During my last trip to Belgium, I decided to find and gather ingredients to make a true regional beer (gruit). In this case it was easier said than done, as my time was limited (5 days). It was early April, and I didn’t have anyone who could help me identify the right plants. In fact, I’d left Belgium so long before that I didn’t even know which plants were available locally. A quick online search for wild ingredients used to make traditional Belgian beers/gruits a long time ago indicated that I could potentially find such plants as wild rosemary, bog myrtle, yarrow, wormwood, ground ivy, dandelion roots, sea wormwood (Artemisia maritima), wild hops, and horehound. While I was familiar with a few of these, most weren’t ingredients I was used to finding in California. From experience, I decided to search for plants based on their environment, and each day I took a hike for a few hours in the local forests, near rivers, in areas surrounding lakes, and, just for fun, around the beautiful Belgian town where I was staying. Not only did I have a great time learning about local edible and medicinal plants, but I was extremely happy to find traditional brewing ingredients within a couple of days. I ended up using dandelion roots, which were plentiful in the farm fields surrounding the village; common wormwood (Artemisia vulgaris) and yarrow, found on the edge of a local river; and ground ivy from the nearby forest and my brother’s garden. One of the main area industries was making sugar from sugar beets, so I decided to use the local brown sugar. I used ground ivy fresh, as most of its lemony/tangy taste tends to fade when the leaves are dehydrated. The yarrow and wormwood had much less flavor than what I’m used to in Southern California, but it was early spring in Belgium, and I know the best time to collect both ingredients would have been during early fall. Instead of lemons, I used four stems of bitter dock (Rumex obtusifolius). Rhubarb stems would work, too (though not the leaves, which are toxic).

Wild Belgian Beer

This beer ended up being quite nice and mild. It was not as aromatic as my regular mugwort-lemon beer, but it had a nice bitterness. This was my first time using ground ivy; next time I plan to double the amount and experiment with using the dehydrated herb as well. Having spent my childhood in the local forests, I felt a very strong connection to this brew. It reminded me that, as a wildcrafter, I was not fermenting ingredients just for flavors. Through the process of wild fermentation, I was really preserving moments in time, places, and memories. I’m sure it’s a beer my father would have loved to try.


  • 11⁄4 pounds (567 g) brown sugar
  • 2 ounce (6 g) wormwood or mugwort
  • 2 ounce (6 g) yarrow
  • 3 ounce (9 g) chopped dried dandelion roots
  • 3–4 crushed stems of bitter dock, each 3–4 inches (7.5–10 cm) long,  or 1–2 lemons
  • 1 gallon (3.78 L) water
  • 5 ounce (14 g) fresh ground Ivy Yeast (wild or commercial)


  1. Place the sugar, wormwood, yarrow, dandelion roots, and bitter dock stems into a large pot with the water. Bring to a light boil for 30 minutes. Add the fresh ground ivy after 20 minutes of boiling.
  2. Remove the brew from the heat and strain it into the fermenter, then add the yeast. When I’m using a wild yeast starter, I usually use 1⁄2 to 3⁄4 cup  (120–180 ml) of liquid. Position the airlock or cover your fermenter with a paper towel or cheesecloth. Let the beer ferment for 10 days. Start counting when the fermentation is active (this may take 2 to 3 days with a wild yeast starter).
  3. Siphon into 16-ounce (500 ml) swing-top beer bottles (you’ll need seven bottles) and prime each one with 1⁄2 teaspoon (2 g) white or brown sugar for carbonation. Close the bottles and store in a place that’s not too hot. The beer will be ready to drink in 3 to 4 weeks.
