Heat Treatment Offers Wine Growers Many Benefits

Thermal Plant Treatment (TPT) is a multi-purpose sustainable technology that provides heat in the vineyard to assure fruit set, improve wine quality, dry off crops after rains and provide pest control. After encouraging fruit set and wine quality results in 2012, trials were expanded in 2013.  2013 field trials included 11 blocks in CA and 5 additional winery company trial blocks that were conducted in Oregon, Washington and New Zealand.  2013 fruit set results measured on the 11 California trial blocks 3-6 weeks after bloom were consistent and dramatic with TPT treated blocks averaging 24% more berries per bunch than control blocks. Test wines were made from 12 test and 12 matching control blocks by Fresno State University and then compared in a blind tasting by a panel headed by Master of Wine, Philp Goodband. It was concluded by the panel that TPT enhances wine quality. In 2014 AgroThermal Systems began to commercialize the technology in California and Oregon through direct sales of equipment and Treatment Application services.

Experts Judge TPT Wine To Be Better

Adelsheim Vineyard in Newberg, Oregon took the lead in testing TPT on its Pinot Noir during the 2012 crop year and saw similar characteristic differences repeated in two trial blocks of their Pinot Noir, 2013 vintage.  Twelve other 2013 wine trials have now been blind tasted by University and industry experts and the results showed there were clear sensory differences with consistent preferences for the wines created from heat treated grapes. Master of Wine, Philip Goodband tasted all test and control wines and was intrigued by the differences and the potential of the technology to improve wine quality. “These wines have been produced for chemistry analysis and study, so evaluating them over time is not possible, but the flavor characteristics of the wines from treated grapes were in my view noticeably better. In finished wines these early stage advantages would likely improve with aging to an even greater degree,”
