The 2015 Reserva Old Vines is a field blend from old vines (average age: 70 years) aged for 16 to 18 months in 65% new oak (85% French, the rest American), depending on the lots. It comes in at 14.5% alcohol. This year, as reported in my first look at this about a year ago, Crasto eliminated two southern-exposure plots in the vineyard because they were not fresh enough. Plus, Maria Teresa and Vinha da Ponte lots were eliminated because both produced separate wines this year. This has fleshed out a bit, showing a mouth-coating demeanor and texture that it didn't originally reveal, but it has not changed a lot. It retains the elegance and freshness I expect from the vintage and the brand. It still is young, a little unevolved and has a long way to go to develop complexity. The tannins are relatively ripe, so you can drink this now if you want to, but that will not be its highest and best use. Come back in another couple of years for better results. There were 90,000 bottles produced.
