Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
To Make Birch Wine
Ingredients
Directions
Collect the sap
Collect birch sap by boring holes in the trees and placing bottles underneath.
Cork the bottles tightly.
Wax the bottles until ready to make the wine.
Make the must
Boil the sap and add 4 pounds of sugar and the lemon peel.
Boil for another hour, skimming regularly.
Pour the mixture into a tub and let it cool slightly.
Add a toast spread with yeast.
Stir twice a day for 5-6 days.
Ferment and bottle
In a cask, place a lighted brimstone match.
Pour the wine into the cask and lightly bung it until fermentation is complete.
Seal the cask tightly for about 3 months.
Bottle the wine.

Shared aroma: 2-nonenal (fatty, green).
Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Birch sap
- Forms the liquid base of the wine, supplying the fermentable material.
- Loaf sugar
- Provides the sugar that yeast converts into alcohol during fermentation.
- Yeast
- Converts the sugars into alcohol and carbon dioxide during fermentation.
- Lemon peel
- Adds aroma and a light citrus flavor to the wine.
The step that matters
Stir twice a day for 5-6 days. Regular stirring keeps the yeast in contact with the sugars and releases carbon dioxide, helping fermentation start evenly and steadily.
