TasteVin is a small silver cup and was used by sommeliers in France to taste and evaluate wine. I would like the logo to somehow incorporate a modernized version of a tastevin. I uploaded several pictures of tastevins.
Here is some information about the tastevin from Wikipedia:
A tastevin is a small, very shallow silver cup or saucer traditionally used by winemakers and sommeliers when judging the maturity and taste of a wine.
The saucer-like cups were originally created by Burgundian winemakers to enable them to judge the clarity and color of wine that was stored in dim, candle-lit wine cellars. Regular wine glasses were too deep to allow for accurate judging of the wine's color in such faint light. Tastevin are designed with a shiny faceted inner surface. Often, the bottom of the cup is convex in shape. The facets, convex bottom, and the shiny inner surface catch as much available light as possible, reflecting it throughout the wine in the cup, making it possible to see through the wine.
With the advent of modern electric lights, tastevin have very little practical use, although sommeliers often wear them on a ribbon or chain around the neck as a nod to tradition.
