2018 AND 2017 GAJA VINTAGES WITH GIOVANNI GAJA

Giovanni Gaja, the fifth generation to work for his family's winery in the Piedmont region of Italy, talks about the effects of rain and global warming on this season's crop. "When we think about climate change, we tend to think only about the heat and warmer temperatures," he said. "Climate change is not only that. It's all the rest. It really stretches all the excesses."Giovanni explains to James what went into the making of Gaja's 2018 Barbaresco, which James says is "long and racy," and compares it with the 2017. They also taste the 2017 Barolo.
