Homemade Grape Must: The Sweet Base for Greek Syrups and Dishes

Learn how to make grape must at home, the sweet juice from crushed grapes used in winemaking, for grape molasses, and as a base in traditional Greek recipes.

Grape must is the freshly pressed juice of grapes, full of natural sweetness and flavor. It is a key ingredient in winemaking and in the production of grape molasses (petimezi), and it also appears in several traditional Greek dishes, adding a unique fruity depth.

Making your own grape must at home is simple and rewarding. You can use it right away in recipes, store it in the fridge for a few days, or freeze it for months. The optional addition of wood ashes helps clarify the juice, a technique used in some traditional preparations.

Method

  1. Rinse the grapes thoroughly and spread them on clean tea towels or paper towels to dry completely.
  2. Remove the grapes from their stems and place them in a very large mixing bowl or a large cooking pot.
  3. Crush the grapes using your hands, a weight, or a juicer to extract the juice.
  4. Set a strainer over a bowl or pot and pour the crushed grapes into it. Strain to separate the skins from the juice.
  5. Press the skins in the strainer to squeeze out any remaining juice, then discard the skins.
  6. Without ashes: Pour the grape juice (must) into a large pot, bring to a boil, then reduce the heat to medium.
  7. Without ashes: Skim off any foam and impurities from the surface, then turn off the heat and let the must cool to room temperature.
  8. Without ashes: Strain the must through a muslin cloth, passing it through twice.
  9. Without ashes: Store the must in bottles or jars in the fridge for up to 2 days, or freeze for up to 6 months.
  10. With ashes: Pour the grape juice (must) into a large pot and add the ashes.
  11. With ashes: Bring to a boil, then lower the heat to medium and skim the surface until it is clear of all foam and impurities.
  12. With ashes: Turn off the heat. If using a stainless steel pot, let the must cool in the pot overnight. Otherwise, transfer it to a large glass bowl and let it sit overnight.
  13. With ashes: The next day, any remaining impurities will have settled at the bottom. Ladle the clear must from the top into clean jars or bottles, passing it through a muslin cloth first.
  14. With ashes: Store in jars or bottles in the fridge for up to 4 days, or freeze for up to 6 months.

💡 Tips

  • Use ripe, sweet grapes for the best flavor and natural sweetness.
  • If you don't have a juicer, you can crush the grapes in batches with a potato masher.
  • The ashes are optional but help clarify the must; make sure they come only from burnt wood, not charcoal or treated wood.
