Esipz produces a number of WSET Wine Kits. The Wine and Spirit Education Trust or WSET is the world's premier, wine and spirits educational entity with over 120,000 students studying with them each year. They offer classes in multiple languages in both in person and online formats. Online classes schedule available here.
These kits are curated by the educators at the Wine Education Institute who offer these classes on a regular basis. These kits are not sanctioned or endorsed by WSET although each kit is specifically designed to accompany the WSET Level 1-3 Award in Wines Program.
