Assistant Winemaker Tami Lotz pouring wine

Tami completed her degree in Viticulture and Enology at UC Davis and interned at Mumm Napa. After spending a year working and learning about wine in Germany, Australia, and Chile, she returned to Mumm Napa in 2003 as assistant winemaker under Ludovic Dervin. She was named head winemaker in 2019. In addition to crafting award-winning sparkling wines, Tami loves cooking, traveling, reading, and hiking in the hills of Napa Valley. She also volunteers with Napa Country Wildlife Rescue at their Songbird Clinic.

It’s really difficult to pick a favorite Mumm Napa wine. Every vintage and every blend is different. But Devaux Ranch is a blend that is a true expression of place and of the vintage. It’s a vineyard to which I feel a special connection.
