Why it works: Cider and vinegar are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓
Grape Vinegar
Ingredients
Directions
Prepare the grapes
Pick over grapes and remove pulp from skins, placing firmly into a container.
Add cider vinegar to grapes in a ratio of 1 quart per 3 quarts of grapes, mix well.
Cover the mixture and stir thoroughly every day.
Extract and sweeten
On the fourth day, press the mixture through a cloth to extract the juice.
Add sugar to the juice in a ratio of 5 pounds per 3 quarts, boil until clear, skimming as needed.
Simmer or boil slowly for 10 minutes, then bottle when cold.
Store
Seal the bottles and store in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapes
- Provide the juice and flavour that form the base of the vinegar.
- Cider vinegar
- Acidity that ferments and preserves the grape mixture while it steeps.
- Granulated sugar
- Sweetens the juice and balances the sharpness of the vinegar.
The step that matters
Boiling the juice with sugar until clear. Boiling dissolves the sugar fully and coagulates fine particles so they rise as scum. Skimming removes them, leaving a clear, stable syrup that keeps better in the bottle.
Swap the grape
How well each one fits the dish's main ingredients (cider, vinegar, sugar):
- Applefits better
- Plumfits about as well
- Pineapplefits about as well
- Grapethe original
Fit is the average pairing score against cider, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
