The Wines With Altitude issue of The Cellar Door focuses on grapes that grow on the slopes of the hills and mountains of the world's top wine regions. We explore how high altitudes affect wine styles, and how we define "high altitude" in regions from Aregntina and Chile to California, France, and Italy. We also hit the Autostrada and back roads of northern Italy on a driving tour through the hilly regions of Alto Adige and Veneto. In addition, we talk about classic Pinot Grigio styles, examine the challenges of choosing wine for air travel, and our wine experts put together a plant-based comfort meal paired with all the right winter wines.
