I'm not Jim, (non-FL category) but Scar of the Sea is from Mikey and Gina Guigni (she also makes Lady of Sunshine) and they're here in San Luis Obispo, working from vineyards that are biodynamically farmed (maybe some are only organic) in the area. Low intervention, highly aromatic, just really solid winemaking (Mikey also makes the wine for La Lomita Ranch, a vineyard at the base of Islay Peak that has no relations to anything made from Islay Peat). I like the wines a lot.
Along those same lines are Dunites, another mashup couple of winemaker and vineyard manager resulting in low intervention wines that rely on acidity and structure than voluptuous oak. They have a tasting room right in downtown SLO.
Finally, there's Outward, another young couple based around here working with local organic/bio fruit and making really nice wines. They're rock climbers (Ryan Pace and Natalie Siddique not the wine) and are in the process of opening a tasting room in Grover Beach, a place that's just up the road from Oceano, which is where the Dunites lived back in the early part of the last century. They were refugees from society, living in the sand dunes to avoid having to deal with the ills of society. As it turned out, people like Ansel Adams, John Cage, and John Steinbeck would hang out there to commune with the members of the commune. The last of the Dunites died in the 1970s and now the place is overrun with dune buggies driven by beery-eyed refugees from Hanford and Bakersfield. So much for the intellectual Utopia the Dunites created. There's some historical markers down by the Amtrak station and the Dunites winery was named in honor of the dune denizens but that's about it. Kind of an Ozymandias story...
-Eden (Mr. Hanlon's recommendations are spot on! I'm particularly fond of The Joy Fantastic wines, made by the Holus Bolus folks -- Amy is a MW, Peter just makes killer wine, and Ceritas is probably the best Chardonnay made in CA these days. I'm on the Sandlands list, and don't forget Ultramarine, and there's a new sparkling wine producer called Haliotide that's light years ahead of everyone other than Ultramarine....it's all about the winemaker's vision when it comes to bubbles, no?)
