"Opus One only produces one blend every season, and their vintages represent some of the most upscale and expensive wines on the market. The estate, which is meticulously maintained, is fittingly grand. We recommend making an appointment for one of their informative tours if you have time—they have a cavernous cellar (the French oak barrels are only used once) and a very large lab, plus, it's fascinating to find out what it takes to make wines that usually sell for more than $200/bottle.
