The 2015 Redoma Reserva Branco is a field blend from old vines that were aged for nine months in 30% new French oak (the remaining barrels of varying ages). It comes in at 12.5% alcohol. This adds a couple of layers of depth to the regular Redoma Branco, more power and, of course, more oak. However, this will have a long aging curve and it should easily pull it in. In fact, it is becoming well integrated even now. Underneath, you get fine acidity and it drinks beautifully, but it will acquire more complexity and harmony in a few years. This, unlike the regular Redoma, really needs food. Don't treat it as a porch-sipper and don't drink it too cold.
