Fall Line Winery is owned and operated by winemaker Tim Sorenson and his wife, Nancy Rivenburgh.

In summer 2000, Tim completed Introduction to Winemaking, given by the Department of Viticulture and Enology at the University of California-Davis. In May 2001, Tim joined the staff of a downtown Seattle specialty wine shop, where he worked part-time for over three years. While there, he became acquainted with many highly regarded winemakers, including Benjamin Smith of Cadence Winery.

In fall 2002, Tim embarked on what was to become a two-year informal 'vinternship' with Cadence Winery. From the beginning, Ben welcomed Tim's involvement in every aspect of winemaking - from making trips to the vineyards to inspect vines and sample the fruit, to running analytical tests on juice and wine samples, crushing, pressing, racking, bottling, etc.

For as long as he has been enjoying wine, Tim has had a deep appreciation for the artistic and cultural aspects of wine and winemaking. He is especially intrigued, though, by the science of wine. Since completing the Davis course, Tim has amassed a significant collection of texts and other references on viticulture, enology, and the world of wine - which he continues to actively study.
