What Is Grape Must?
The term “must” comes from the Latin word vinum mustum, meaning “young wine” or “fresh grape juice.”
When grapes are harvested and crushed, the resulting mixture is called grape must. Unlike regular grape juice, grape must contains:

- Grape skins
- Seeds
- Pulp
- Sometimes stems
This mixture contains natural sugars that yeast later converts into alcohol during fermentation.
