After that, not-so-hot hot springs (mineral springs, though).
The next day, we intended to vineyard-hop but without reservations we basically only hit one (and had lunch at another that offered samples with lunch). We learned more about the different conditions that inform the grapes, about how those conditions are different even just across the Andes in Argentina. Our guide told us about the time an earthquake destroyed a lot of wine that was in the process of fermenting, and the ill-smelling contents of the breached barrels flooded the streets. We loved everything we tried, and the guide was super informed and passionate.
