The Rumiano Brothers were known for their high-quality products and for their development of Dry Jack cheese. Dry Jack was originally sold “fresh” to Italian businesses and distributors in the San Francisco region, where the cheese would be aged in the cool cellars below the merchant’s shops. The Rumiano Brothers changed this process by aging the cheese in their own hand-dug cellars. This allowed them to take the fully matured product to market. Demand and sales rapidly increased. Because they were the first to offer this aged Dry Jack, the Rumiano Brothers are considered the original developers of Dry Monterey Jack Cheese.
