Among the Texas wineries who brought back medals from the TEXSOM competition was Pilot Knob Vineyard and Winery.

No doubt about it: Texas wineries are growing gold-medal grapes.

A total of 156 medals (23 of those gold) were given out to state wineries at this year’s TEXSOM International Wine Awards, the results of which were announced earlier this week.

The wine that seemed to dazzle the most at TEXSOM, a Dallas-based wine competition that has evolved in its more than 30-year history to become one of the top wine competitions in the U.S., according to a press release, is tempranillo, a Spanish grape that has thrived in Texas’ warm climate and soil and has helped to establish this region as bona fide wine country.

Six tempranillos from five different wineries struck gold, including Wedding Oak Winery Tempranillo Reserva Texas High Plains 2012, Becker Vineyards Tempranillo Reserve Texas 2013 and Pedernales Cellars 2012 Texas Tempranillo and Tempranillo Reserve.

“It is continued proof that a focus on the right varietals and winemaking practices for our region can produce world class wines made from Texas grapes,” Pedernales Cellars’ David Kuhlken said in the press release.

His winery took home the most gold medals of any other Texas winery, a total of four, with wins additionally for the Hill Country winery’s 2014 Texas Vermentino and 2014 Texas Viognier. Although the Tempranillo Reserve is the only TEXSOM award-winner in current rotation at Pedernales’ tasting room in Stonewall, winery staff plans to add the vermentino later in the year, once it’s officially released this spring.

Pilot Knob Vineyard and Winery, in Bertram, was among the first-timers to the TEXSOM competition. Although its debut at the competition didn’t yield any gold medals, three of Pilot Knob’s flagship wines received silver (the 2014 Viognier) and bronze (2014 PK Cuvee and 2013 Franco Rojo Reserve). These are available for trying at the tasting room.

“We look forward to future TEXSOM competitions and the opportunity to impress the judges with the wines we’re currently readying for release,” Pilot Knob co-owner and winemaker Craig Pinkley said in a press release.

The blind-judging took place last month in Irving, near Dallas, by nearly 70 wine experts from around the U.S. They awarded 1,708 wines, with 227 gold, 629 silver and 852 bronze winners.

Two Pedernales Cellars’ tempranillos brought home the gold: Pedernales Cellars Tempranillo Texas 2012 and Pedernales Cellars Tempranillo Reserve Texas 2012.
