The 2013 Tinto Tonel No. 3-4 was aged for 40 months in large Portuguese and Brazilian tonels, then held back for 22 months in bottle. It comes in at 14.5% alcohol. When last seen, this was brilliant. It is on track and developing well. Dark and more closed, this lacks the lively and fresher style of the regular Estate Tinto (either the 2014 or the 2015), but it has more power and plenty of depth. The flavor profile is perhaps not quite as enticing, as it is acquiring a bit of a darker feel, but this is well done. It is a long-term wine that is nowhere close to finishing its development. It is also not at peak. Grab some if you can find it and have a cellar. There will be, I'm told, a small amount of Tonel No. 3-5 in 2015, but nothing after that until 2021.
