The 1992 vintage was a great year in just about all parts of California, but especially in Napa. It produced beautiful, solid, and concentrated Cabernets that are lush and opulent, yet also have fine detail and balance.
The winter and spring were mild and bud break was early. Then, the bloom was protracted when cool weather moved in and created an uneven fruit set. Later in the year, clusters had to be thinned to remove the uneven bunches. A wet June caused concern, but July was warm and dry, and ripening moved on at a good clip. The good weather continued into August, until a heat spike caused the harvest to start early as sugars rose and acids started to drop. Just as growers were beginning to panic, fearing it would be a fevered, compressed harvest with everything ripening at once, the heat subsided. Warm days, cool nights, and foggy, cool mornings replaced the heat, slowing the pace and allowing the picking to resume at a more normal pace and a little more hang-time for flavors and tannins to ripen and develop.
Overall, it was an excellent year, producing ripe, plush, and rich Cabernets that were fairly accessible early on, and have been great over a long window of time.
