Why it works: Raisin and almond are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 1,781 recipes. Both carry 2-nonanone, which smells fruity, floral. The science ↓
Birch Wine
Ingredients
Directions
Prepare the must
Boil the birch juice, sugar, and raisins for 20 minutes.
Transfer the mixture to a tub and add the crude tartar.
Allow to ferment for several days.
Ferment and age
Strain the mixture and transfer it to a cask.
Tie the almonds in a muslin bag and add to the cask.
Once fermentation ceases, remove the almonds and seal the cask.
Let it stand for about 5 months before fining and bottling.

What each ingredient does
- Birch tree juice
- Forms the liquid base that the sugar and yeast ferment into wine.
- Sugar
- Feeds the yeast, producing alcohol during fermentation and adding sweetness to the finished wine.
- Raisins
- Add fermentable sugars, nutrients for yeast, and fruity flavor.
- Crude tartar
- Adds acidity that supports fermentation and gives the wine a sharper, balanced taste.
- Almonds
- Contribute nutty aroma and flavor as the wine ages.
The step that matters
Remove the almonds and seal the cask once fermentation ceases. Sealing a cask while fermentation is still active can trap carbon dioxide and build pressure. Waiting until activity stops keeps the cask stable, and removing the almonds then stops them adding excess bitterness during aging.
