A crazy field blend of 30 Mediterranean and Tuscan grape varieties, with 2,800 bottles released, the 2017 Jassarte evokes a "Jurassic" theme in viticulture because the ancient world of wine is magically brought to life in this offbeat, almost paleontological, assembly. I've tasted many vintages of this wine over almost 20 years. I think this is the best and most-balanced edition I have sampled so far. Balance is the operative word, because imagine how challenging it is to make a wine with so many moving parts from an experimental vineyard that mimics a pre-phylloxera garden. Dark fruit and blackberry are followed by toasted spice, graham cracker and some of the other aromas that we saw in the other new releases from Guado al Melo. You can't beat this level of creativity.
