Raspberry and Blueberry Soda: Brewing Up Some Bubbles

One of the best ways to begin brewing is by dipping your toes in the bubbling waters of homemade soda. This recipe for Mountain Raspberry and Blueberry Soda features just a few local ingredients and allows you to get as creative as you’d like. There are no real rules when it comes to this fun and bubbly beverage.

How to Make Raspberry and Blueberry Soda

This is probably the prettiest soda I’ve ever made, and it’s super tasty as well.

The recipe is extremely loose, so don’t overcomplicate things. If you live in Oregon or on the East Coast (Vermont, Maine, New York), you may use different trees such as spruces or pines (white pine, blue spruce, and so on), and of course different berries. If you live in Maine or Vermont, by all means use your wonderful maple syrup as a sugar source. It’s all good.

This is very much a “concept” drink.

Procedure

1. Clean your fermentation vessel and place your fresh ingredients in it. Add spring water (don’t use tap water, which may contain chlorine) and sugar. There are no real rules for this simple fermentation: Just pack 80 percent of your jar with what you have collected/purchased. I use around 50 percent berries and 50 percent pine/fir. Cut the tips of the needles to help extract the flavors. Start with around 1⁄2 cup (120 ml) of sugar for 1⁄2 gallon (1.89 L) of water.
2. Add yeast (wild yeast starter or champagne yeast). Screw on the lid of your container, but not too tight; you want fermentation gases to escape. You can also cover it with clean cheesecloth or a paper towel. Stir gently two or three times a day with a clean spoon. Taste as you go, and judge by flavors. When you like what you drink, you can stop. It may take 3 or 4 days or more. I usually don’t leave the fruits in the liquid for more than 3 days (some get mushy).
3. Strain and pour the liquid into recycled plastic soda bottles or glass swing-top bottles. Check the pressure after a day or so.
4. When you’re satisfied with the level of carbonation, place your soda in the fridge and enjoy the next day. I like to drink it within a week.
