Vat-Pasteurized. Our dairy products have been enjoyed in homes and fine restaurants for more than a century. Today, we continue to vat-pasteurize to preserve the natural sweetness of our fresh milk and cream. This traditional method, which heats milk gently, takes more time and attention. But the exceptional flavor makes the extra effort worthwhile. Thank you for your patronage - The Corby Family. Founded in 1888. Pittsford, NY.
