There was a lot of research done, before I got started, and it continues. The Grand Valley AVA is rather large and could easily be broken up into 4, if not more, sub appellations. What to plant in the vineyards in Palisade depends on what part of the valley the vineyard is in. Then, depending on the growing season, certain varieties from different locations stand out. The main vineyard in Palisade is currently being replanted from 17 varieties to 4 with an experimental block and new varieties to try. The winery in Palisade will then source the best grapes from local vineyards in Palisade area, West Elks AVA, and possibly Moab.ype your paragraph here.
