What if you could hang out with experienced grape growers, ask them about the science of grape growing, vineyard operations, and more; then take an insight or two to improve your vineyard and ultimately the quality of the wines you produce? That's what we do each week on the Vineyard Underground. Hosted by Fritz Westover –– viticulture expert more than 20 years of experience in the vineyard industry –– every episode is an in-depth look at grape growing methods, care, and even complicated matters of fertilization and pest and disease management? The goal is to provide you with an understanding of the complicated aspects of viticulture science so that experienced and even first-time grape growers will be able to understand and implement new practices in their vineyard.
