The Wine Scholar Guild (WSG) and Terroir Wine Services (TWS) have worked very closely together, and with the instructors in each region, to create itineraries that provide a thorough overview of the region as well as a very enjoyable time for participants. The Wine Immersion Study Trips are part of the Wine Scholar Guild’s Master-Level study program. The trips are then organized and operated by TWS. TWS is also responsible for sales and customer service for the trips. You will pay the trip price to TWS, and it will appear on your credit card statement as TERROIRWINE.
