Although Kistler's 1991 Chardonnays are not as opulent, explosively rich, and authoritative as their 1990s, they are among the greatest of the vintage. A star is the 1991 McCrea Vineyard, a light golden-colored, tightly knit, rich wine, with a spicy, vanillin, honey, buttery, apple-scented nose and flavors that display impressive acid, integration, and balance. This wine should blossom with several more months of bottle age and last for 2-3 years. The extraordinary team of Steve Kistler and Mark Bixler fashions exhilarating Chardonnays that are compellingly complex, lavishly rich, and exceptionally well-balanced. One can quibble over which is best, but they are all immensely satisfying Chardonnays. Given how irresistible they are young, most of them are probably drunk within hours of purchase. That may be a shame, as Kistler's best cuvees of 1987 and 1988 are aging exceptionally well.
