The Technical Spotlight is a regular feature highlighting wineries in North America that have recently
opened or undergone major renovations and improvements. Wines & Vines seeks to report how
facility design and winemaking equipment is used to achieve a particular winemaking style while also
exploring new trends and techniques being used in the industry. If you think your winery would be a
good candidate for the feature, contact us at edit@winesandvines.com.
