Husband and wife Peter D. and Brenda Oldak didn't have any specific plans when they moved onto a 12-acre New Hampshire farm in 1977. A few years later, though, Mr. Oldak began experimenting with growing grapes. Through a decade of trial and error, he began improving his techniques, and when he won his first few medals in 1992, he decided to bring his operation up to the commercial level. Peter and Brenda are still hard at work perfecting their wines as the owners of Jewell Towne Vineyards, a boutique and community-supported winery occupying the former farm. Daily tours lead visitors along the sunny riverside slope where more than 20 varieties of American and European grapes now grow, and into the processing, fermentation, and barrel rooms. During said tours, guests follow the same path as the wines, all of which are made entirely from Jewell Towne's grapes. These libations are also available for sampling in the rustic post-and-beam tasting room that, along with an art gallery, fills the former farmhouse.
