AgroThermal Systems Announces Cab Franc Results from Trials Conducted at Mission Estate in Hawke's Bay, New Zealand


Date: 10/23/13

October 22, 2013 Walnut Creek, CA- Results from the New Zealand Cabernet Franc Mission Estate wines trials are proving a strong case for the application of Thermal Plant Treatment in vineyards. They are consistent with previous trials conducted in North America during 2012 and show continued developments supporting the effects of Thermal Plant Treatment on fruit set and wine quality.

Wine from both treated and control grapes was produced by the Eastern Institute of Technology (EIT) at their Hawke’s Bay Campus and harvest data was provided by Fruition Horticulture, an independent agricultural research company. Harvest data for the Cabernet Franc showed that TPT fruit set averaged 18.4 percent more berries per bunch and the average berry weighed 18.6 percent less than control. In addition, the treated grapes had somewhat higher BRIX and lower acids. According to Dr. Art Dawson, chief science officer at AgroThermal Systems “these fruit set results are very consistent with trails we have done in the US during 2012 and 2013 where fruit set in heat treated blocks has averaged 24 percent more than matched control blocks.”

A chemistry analysis provide by EIT showed that TPT treatments led to a very different wine chemistry when compared to control grape wine with substantial difference in tannins, phenolic and free anthocyanins as shown in the table below.
 

According to Marty Fischer, AgroThermal CEO, “We have had results in the past showing that TPT changed fruit chemistry, but the EIT data was more dramatic than we had seen in past work. This grape and wine chemistry phenomenon is being studied at Fresno State University using seven varietals from the 2013 North American harvest. We will know a lot more when that data is completed.” The company reported earlier this year that Pinot Noir made in 2012 at Adelsheim Vineyards from treated grapes was evaluated by several experts as being different and preferred over wine made from control grapes.

Philip Goodband, Master of Wine, who recently joined the Agrothermal development team to assist in evaluating and defining the taste profiles of wines treated with TPT, provided a taste evaluation of the TPT Cabernet Franc wine. He is an expert in his field having held senior positions with some of the world’s best know wine producers and served as the wine advisor to the late Queen Mother. “While both samples were clean, healthy, and in good color, youthful purple in the tint, I find the TPT sample has a greater degree of color and definition, shows greater fruit intensity and length at this stage while possessing a more complete all round balance,” commented Goodband.

“The better viticulture and oenology results from the Mission Estate Cab Franc test provide further support that TPT is an exciting new technology that not only can improve fruit set but can have a dramatic effect on wine quality,” said Fischer. The company is currently conducting trials in California, Oregon and Washington state and is expecting both harvest and wine assessments toward the end of the year.
