Available in magnum only, this is an occasional bottling from the winery. A winery spokeperson told me my bottle was entirely 1993 vintage, but not all other bottles are. The wine is extraordinarily fine, but compared to other California bubblies, it's sandpapery and almost harsh at this point. As it warms up in the glass it shows an immense toasted nut and grilled fruit richness with an impossibly long finish. This is one to stash for the long haul.
