What Wino Notion Loved
Visit pending, based on winery profile & reputation
Named for a statistical method,founder Kaj Ahlmann, a mathematician and former GE executive, named the ranch after the Six Sigma quality principles he helped introduce at General Electric.
Bought on a handshake,longtime rancher Russell Rustici agreed to sell the 4,300-acre property after a three-hour tour, trusting the Ahlmanns' intention to keep farming the land.
Vineyard tours by military truck,guests explore the sprawling ranch aboard a rugged Pinzgauer all-terrain vehicle, bumping along dirt roads to vineyards named for each Ahlmann family member.
