Lore Olds first stumbled upon the secluded, rugged slopes of Mount Veeder as a young winemaker at Beaulieu Vineyards in the mid-’60s. Captivated by the frontier-like beauty of the mountain, he was taken under the wing of the legendary Bob Travers of Mayacamas Vineyards. It was here that he first learned to craft mountain wines in the classic Napa mould of the time; wines where refinement, soul and longevity were valued above power. Olds purchased his own property in 1971, just a mile as the crow flies from the Mayacamas cellars. Instead of the in-vogue Bordeaux varieties, Olds chose to focus on ‘California’s own’ grape variety, Zinfandel. In those days, Californian Zinfandel was far from the bombastic, high-octane wines you often find today. It was something altogether more restrained, balanced and red-fruited, with alcohol barely topping 13.5%. The first vines were planted in 1972, the same year Paul Draper selected Lytton Springs Zinfandel to join Ridge Vineyards. In keeping with the frontier spirit, Sky Vineyards is an entirely off-grid affair, relying on solar panels and occasional generator use for all its power. In the cabin-like winery cellar, Sky’s low-tech winemaking remains much as it was in the ’70s, down to the hand-cranked 1906 apple press used since Sky’s first harvest. The wines ferment naturally and mature at length in old French oak. Critically, all Sky’s wines age in bottle for many years before release. Not only does this allow Veeder’s mountain tannins to melt into the wine’s lithe structure, but it also allows its powerful volcanic terroir to unfurl in the bottle. It pays to have friends in California, without whom we may never have found this wonderfully unconventional grower. Sky does not submit wines for review, seldom receives visitors and operates under the radar. For those who discover the wines, though, beauty awaits. Although Lore has taken on more of a consultant role in recent years, leaving the lion’s share of operations in the hands of his daughters Maya and Sky, there are no plans to deviate from the estate’s time-honoured philosophy. Olds is still at harvest, cranking his old basket press alongside his brother. You could say it’s a labour of love. These are some of Napa’s most soulful, terroir-driven, original wines, right down to Lore Olds’ ever-changing hand-painted labels, which adorn each release.
