"Larson Farm & Creamery yogurt is a very firm and surprisingly sweet full-fat product.
  It is made from our own rich Jersey cows’ milk, with nothing added except a non-GMO pro-biotic yogurt culture.
  The milk is heated to 185F, which is required to achieve a firm ‘set’. The milk is then cooled to 110F, culture added, and then bottled.
  Our yogurt is ‘cup set’, meaning the cups are placed in an incubator and held at 110F until the pH drops to 4.6, when the containers are then moved to the walk-in cooler. This result is a nice ‘cream-top’ yogurt with a light layer of nicely soured cream on top of the super-smooth firm yogurt."
Sourced from Tip Top Country Store, Brookfield Ma from Larson Farm & Creamery Wells, VT.
