The good news is that you get a free glass when tasting that can be used again for future tastings - I did not bother keeping the glass. Grgich is one of the older names in the valley and they have an experienced and friendly staff, although it is money up front (or they don't give you a glass). When you walk into the tasting room, you can certainly see the history on the walls and ceiling. They have a large selection of wines to taste and are happy to pour as many and as much as you like, when you can get served. As one of the more well known names, it draws a large crowd and getting through their selection of wines can take some time to attract the different pourers for the next wine, or provide some of the story behind what you are drinking.
