A similarly savvy move was the Trincheros’ prescient early investment in what has become a common sight these days—the single-serving bottle, or “split.”

The Trincheros commissioned research in the 1980s that determined that the increasing number of American adults living alone were hesitant to purchase full-sized bottles of wine for themselves.

The only single-serving sizes available at that time were the plastic 187 ml bottles used by airlines, so Roger Trinchero custom-ordered a small glass bottle mold for Sutter Home. Today, Sutter Home sells more than half of all 187 ml–sized wines in the United States.
