Keep in mind that many California wines are made to drink young although most will age no problem for 3 – 5 years, and more, depending on the varietal. If you decide to store several cases of a favorite vintage, be sure to test a bottle every 6 months to a year so a not to pass by the peak of perfection. Now the fun part, doing the research. You’ll need to start reading industry magazines and tasting to find wines that have potential to age well. Take for example a few notable California wines from the Napa Valley made from either 100% Cabernet grape, or a varietal, with the predominant grape being Cabernet.
