Can Welch’s Grape Juice Ferment? How to Make Homemade Wine
Yes, Welch’s grape juice can ferment if yeast is introduced, converting sugars into alcohol, resulting in homemade wine or vinegar over time.
Yes, Welch’s grape juice can ferment into wine when combined with yeast. This simple process transforms store-bought juice into an alcoholic beverage through natural fermentation. While it won’t rival premium wines, Welch’s wine offers beginners an accessible entry into home winemaking.
The Science Behind Welch’s Grape Juice Fermentation
Fermentation occurs when yeast converts sugars into alcohol and carbon dioxide. Welch’s 100% grape juice contains natural sugars that serve as perfect fuel for this process. The key requirements are:
- No preservatives (sodium benzoate or potassium sorbate will prevent fermentation)
- Active wine yeast
- Proper temperature (60-75°F)
- Airtight container with airlock
Welch’s products meet these requirements, making them ideal for beginner winemakers. Their pasteurization process kills wild yeast but doesn’t affect the juice’s fermentability when commercial yeast is added.
Choosing the Right Welch’s Product
You can use either:
- Bottled grape juice (Concord or White)
- Frozen concentrate (reconstituted with water)
For best results, opt for 100% juice varieties without added preservatives. The frozen concentrate often produces a more robust flavor profile.
Step-by-Step Welch’s Wine Recipe
Here’s a simple method to make one gallon of Welch’s wine:
| Ingredient | Amount |
|---|---|
| Welch’s grape juice | 64 oz (2 quarts) |
| Water | 64 oz (2 quarts) |
| Sugar | 2 lbs |
| Wine yeast | 1 packet |
| Yeast nutrient | 1 tsp |
Fermentation Process
- Sanitize all equipment with a solution like Star San
- Mix juice, water, and sugar in fermentation vessel
- Add yeast nutrient and stir
- Pitch yeast and seal with airlock
- Ferment at room temperature for 2 weeks
- Rack to secondary vessel, leaving sediment behind
