Raising a Glass to a Home Winemaking Legend

Winemaker Rex Johnson with his numerous awards from amateur competitions

WineMaker is saddened to announce the passing of Rex Johnston, one of the most recognized home winemakers we know and a friend of the magazine. Following years of declining health, Rex passed away at the age of 83 near his home in Walnut Creek, California. Rex holds the record of being named the WineMaker International Amateur Wine Competition’s Winemaker of the Year an astonishing eight times since the first competition held in 2002. Since beginning entering amateur wine competitions in 2002, Rex won more than 150 Best of Show awards and 13 Golden Bears at the California State Fair Home Wine Competition. He was a member of the Sacramento Home Winemakers club where he was a mentor to other home winemakers and quick to share his experiences to further the hobby. 

 Rex began making wine at home from dandelions and fruits in 1965, but his sweet, dessert wines from grapes and fruits grown on and around his own property are the ones that would go on to garner so much attention. Rex and his wife, Barbara Bentley, were fixtures at the annual WineMaker Conferences for a decade, where Rex’s infectious smile and kindness was as memorable as the numerous walks he and Barbara would make to the winner’s podium each time his name was announced at the awards reception.

 It is with a heavy heart all of us at WineMaker magazine raise a glass of his Bentley Cellars Elephant Heart Plum Wine in Rex’s honor.

Rethinking Vertical Shoot Position Trellis Systems

A new study out from UC-Davis has shown that the popular vertical shoot position (VSP) trellis system is likely not the best trellising for warmer, sunnier sites like those found in California. The study looked at six different trellis systems, each at three different irrigation levels for two consecutive seasons. They tested a standard VSP trellis, two variations of the VSP system, a single high-wire cordon system, a high quadrilateral system, and Guyot-pruned VSP system. The irrigation levels were at 25%, 50%, and 100% of the crop’s evapotranspiration level. 

The researchers concluded that the single high-wire cordon system had higher yields and accumulated anthocyanins at harvest. They found that the VSP trellis had reduced anthocyanins and that the leaf arrangement with this style of trellising was overexposing the fruit to sun. Their conclusions were clear for those vineyards in a hot and sunny climate: It’s time to replace your VSP trellises. The irrigation aspect of the study was less surprising with higher irrigation leading to larger berry size and yields, but lower anthocyanin and flavonol levels. https://www.frontiersin.org/articles/10.3389/fpls.2022.1015574/abstract

More Great News For Grape Growers

In the August-September 2022 issue of WineMaker, we reported on a big potential breakthrough in the fight against glassy-winged sharpshooters, a scourge of California grape growers. In another breakthrough, scientists say they may have found the pathway and potential cure for grapevine trunk diseases (GTDs). GTDs are a fungal issue that has caused an estimated $1.5 billion in annual damage to vineyards according to a study done in 2012. Eutypa dieback and esca are two commonly known GTDs. The researchers found that a mix of reduced iron (Fe2+) and hydrogen peroxide combine in a complex interaction among several fungal species and are released into the wood. It is here that combination can prove deadly to grapevines because it releases free radicals. Free radicals are the reason we are told to take our antioxidants . . . they’re not good for any living creature.

The good news is that this combination of iron and hydrogen peroxide should be easily stopped by antioxidants and a common compound we know as chelating agents. So what is a chelating agent? It’s a chemical compound that reacts with metal ions to form a water-soluble, stable complex. They can be found in our food, in cleaning products, in medicines (such as cancer treatments), and water treatment systems, among other uses. So potentially by treating the wounds (growing fungi) on the grapevine trunk with a chelating agent and antioxidants, the reduced iron can be removed from the equation and hydrogen peroxide can be turned to water. https://www.frontiersin.org/articles/10.3389/fpls.2022.921961/full

The World Of Natural Wine

While the world of natural wines can be fairly polarizing in some wine circles, there is no denying that it can produce some interesting wines. Made from grapes alone — organically farmed, fermented, aged, and bottled without additives — they’re a winemaker’s expression of linking wine directly to nature. Author Aaron Ayscough looks to navigate this movement in The World of Natural Wine. Meet the obsessive, often outspoken, winemakers; learn about the regions of France where natural wine culture first appeared and continues to flourish today; and explore natural wine in Spain, Italy, Georgia, and beyond. https://www.workman.com/products/the-world-of-natural-wine/hardback
