Byrne Dairy is a family-owned, 84-year-old dairy processor that has kept up with the times. The Syracuse, N.Y.-based company started in 1933 with fresh milk in glass bottles. Today at its Ultra facility, Byrne manufactures various extended shelf life milk products with code dates ranging from 70 to 180 days.

In addition to milk, Byrne Dairy makes ice cream and cultured dairy products using conventional, organic or grass-fed milk. It also produces nondairy products. In addition to its own brands (Byrne Dairy and Byrne Hollow Farms), the milk processor co-packs for customers that include dairy brands, grocers and foodservice accounts. Byrne also provides dairy ingredients for other manufacturers.
