Six Sigma Ranch and Winery

Six Sigma focuses on producing small lot, high quality wines. From vineyard to crushpad to barrel, each step is carefully monitored to make sure that only the best fruit goes into every bottle.
Kaj and Else Ahlmann’s love of nature is the driving force behind how they manage their scenic 4,300-acre ranch. The naturally farmed ranch uses Six Sigma methods to produce the highest quality wines.
And be sure to take a tour around the ranch in their rugged Pinzgauer vehicle!
