This episode features Scott McLeod, winemaker, and one of the founders of WineXRay. Our conversation covers Scott’s background building the Francis Ford Coppola brands, the development of WineXRay with his business partner Gianni Colantuoni, the color and tannin components that the WineXRay technology measures, its practical uses in a winery, the basic traits of anthocyanins and tannins in wine, the effects of temperature on red-grape phenolic development in the vineyard, consequences of the September 2022 heatwave, extraction dynamics during primary fermentation, the pros and cons of shade cloth in the vineyard, and the limits grapevine virus and diseases have on phenolic synthesis.

This podcast is sponsored by Sentia. The Sentia hand-held wine analyzer is a portable device for rapid measurement of 6 key analytes during wine production - free sulfur dioxide, acetic acid, malic acid, titratable acidity, glucose, and fructose.

Using existing technology developed by Universal Biosensors and applied in human health for over 10 years, you save time and money with Sentia. Sentia has been developed for winery personnel who don’t want to spend hours testing using traditional techniques or waste time preparing samples, sending them off to a lab, and then waiting for results. In less time, you can test, make adjustments, then move on to the next task.

Portability and speed of results are just some of the unique attributes of Sentia. No special skill is required, calibration is automatic, there are minimal or no reagents and it’s cost-effective. PLUS, it’s compatible with major winery management software platforms. Sentia is distributed nationally, as well in Canada, Mexico, South America, and Europe.
