My cup runneth over

At the most incredible dinner I've ever had (and most likely ever will have) we met the sommelier who had done the wine pairings. He was wearing that silver cup-thingy that really pretentious wine people wear like a medal. And I had to know what exactly it is called. Since I couldn't ask him without thoroughly embarrassing myself and family, I dug online. Tastevin in case you're wondering. Pronounced through your nose as Taht-vahN. Ooooo, I'm so cosmopolitan now.
