Our commercial, artisan and farmstead yogurt makers use this culture for many of the custom made yogurts in stores such as Whole Foods, PCC and Organic markets. This culture has a thick, creamy and very smooth texture, very mild aroma and is stirrable. If you prefer even more thickness, use a few drops of rennet. This pouch can make up to 260 gallons of milk. Culture: Streptococcus thermophilus and lactobacillus bulgaricus. This is a food based product that should be refrigerated when received. We do not accept liability, returns or refunds for food based, perishable products.
