High confidence
Exact registry match — this is a specific TTB COLA record. We found a strong match for this wine.
What to Expect
Expect a crisp, herbaceous Sauvignon blanc from ALLOY WINE WORKS. While the exact origin is unknown, this varietal's strong citrus notes are reminiscent of its well-known counterparts in New Zealand’s Marlborough and France’s Loire Valley regions. Its presence across California and other western U.S. wine regions suggests it brings a consistent quality to these markets.
