Saturday, December 30, 2017 - Late Dec 2017: deep purple red color; cranberry, blueberry, blackberry, cherry, mulberry and pomegranate plus vanilla, melon and light toast; soft and lush on the palate; medium/full body; smooth texture; little tannins left; mellow, medium finish.
When I encountered the 2004 Numanthia in the year 2007 it was a young, tannic fruit concentrate. Today it was a fully mature wine. The bottle had been kept in my wine fridge at 50 F the last 5-6 years.
Based on this tasting experience I don’t think the wine will improve further. Moreover, first hints of aging (softness, very weak tannins) can be reported. You don’t need to be hasty but I recommend to drink your bottles in the next 4-7 years. My guess is after that time this wine will start to rapidly disintegrate.
