Are Mulberries Suitable for Making Alcoholic Beverages?

Choosing the Right Mulberry Variety

When selecting mulberries for winemaking, choose varieties with high sugar content, such as the ‘Texas Hardy’ or ‘Illinois Everbearing’. These varieties typically have a sugar content of 18-20% and a Brix rating of 18-20, making them ideal for fermenting. For a 5-gallon batch, you’ll need around 10-12 pounds of fresh mulberries.

Harvesting and Preparing Mulberries for Fermentation

Mulberries are typically ready to harvest in late spring to early summer, when they’re fully ripe and have a deep purple color. To prepare mulberries for fermentation, wash them thoroughly, then crush or puree them to release their juice. The resulting juice should be around 2-3 gallons, which is ideal for a 5-gallon batch. You can use a fruit press or a cheesecloth to extract the juice.

Fermenting Mulberry Wine

To ferment mulberry wine, you’ll need a yeast specifically designed for fruit wines, such as Red Star Premier Cuvee or Lalvin K1-V1116. Combine the mulberry juice with water and a yeast starter to create a must, then pitch the yeast and allow the mixture to ferment at 65-70°F (18-21°C) for 7-10 days. Monitor the specific gravity and pH levels to ensure a healthy fermentation process. After fermentation is complete, rack the wine into a secondary vessel and allow it to age for at least 6 months before bottling.
