What began as an international partnership between Loudoun County, Virginia, and Canelones, Uruguay, has blossomed into a unique opportunity for winemakers to share expertise, strengthen relationships, and grow their respective wine industries.

In 2023, Loudoun County formalized a sister county agreement with Canelones, Uruguay, establishing a relationship focused on economic development, cultural exchange, and international cooperation. While separated by more than 5,000 miles, the two regions share several similarities, including thriving agricultural economies, growing wine industries, and a particular affinity for the Tannat grape.

Tannat, Uruguay’s signature red wine grape, has also found a home in Loudoun’s vineyards. Recognizing this shared opportunity, Loudoun Economic Development, Visit Loudoun, and local wine industry partners helped transform the international agreement into a hands-on winemaker exchange program.

The program takes advantage of the regions’ opposite growing seasons, allowing winemakers to participate in harvests in both hemispheres. Loudoun winemakers first traveled to Uruguay in 2024 to work alongside their South American counterparts, gaining firsthand experience with different production techniques, vineyard management practices, and approaches to winemaking.

In fall 2025, Loudoun welcomed four winemakers from Canelones, who worked alongside local producers at wineries including Walsh Family Wine, Zephaniah Farm Vineyard, and Stone Tower Winery. The exchange provided opportunities to share technical expertise, explore new approaches to Tannat production, and build lasting professional relationships.

As highlighted in Loudoun Now’s coverage of the exchange, the experience has fostered not only professional development but also meaningful friendships between winemakers across continents.

The partnership has also drawn attention to Loudoun’s emerging reputation for Tannat production. The Loudoun Times-Mirror explored the growing collaboration, highlighting how a shared grape variety is creating new opportunities for cooperation and industry growth.

The exchange continued in early 2026, when four Loudoun wine professionals traveled to Canelones for another immersive experience working in Uruguayan wineries.

For Loudoun, the program demonstrates how international economic development relationships can deliver practical benefits to local businesses. By connecting producers with global expertise, encouraging innovation, and expanding opportunities for collaboration, the partnership supports the long-term competitiveness of Loudoun’s agricultural and wine industries.

From shared knowledge to new friendships, the Loudoun-Canelones partnership is proving that international connections can produce meaningful results right here at home.
