At its core, kosher winemaking is identical to traditional winemaking

“At its core, kosher winemaking is identical to traditional winemaking. The key difference is that the entire procedure, both in the vineyards and in the winery, must be overseen and certified by an authorized rabbi. Smaller accommodations must be made along the way, such as only using kosher yeasts for fermentation and not operating the winery on a Saturday (in honor of Shabbat) or holidays, but the framework remains consistent.”
