2019 Grape Harvest Wrap-Ups

As we move into 2020, we wanted to pause to get a quick snapshot of the 2019 northern hemisphere wine grape harvest in both North America and Europe. The theme for North America was cooler temperatures and an overall great year for white wine fans, while Europe was much more varied.

Here in North America, the Wine Institute is reporting that a wet spring turned into a cool summer overall in California with an extended growing season; averaging 1–2 weeks longer than average. Lower sugar and higher acid grapes in general were the result, which is garnering a lot of praise for their balance. The California harvest was down about 2% compared to 2018. Further north in the Pacific Northwest, vineyards experienced decreased Growing Degree Days (GDD) compared to the last several years in almost all AVAs noted by Greg Jones, a professor at Southern Oregon University. Again, a later harvest with lower Brix and more balanced wines resulted. Further north in Canada, moderate heat during the summer yielded to a wetter than normal September with average yield overall. Winemakers and grape growers were striking an optimistic chord overall. Further east, the Finger Lakes and Niagara region’s grape growers are telling a similar tale. Late bud break and moderate heat during the summer transitioned to warm days and cool nights during ripening, extending their harvest dates about 10–14 days.

According to the International Organisation of Vine and Wine (OIV), the European Union production declined by an estimated 15% compared to 2018. A cool rainy spring yielded to record shattering heat waves that struck the EU multiple times during the summer months. France, Italy, and Spain were the hardest hit while further east, Germany Romania, Hungary, and Austria ended up at or even above average yields. Jancis Robinson noted that Germany is expecting high-quality wines from 2019 while the Rioja region in Spain was hit by torrential rains just prior to harvest, kicking grape growers there while they were already down from the summer heat.

Cabernet Sauvignon in a Changing Climate

A collaborative effort between UC Cooperative Extension, Beckstroffer Vineyards, and Duarte Nursery has begun to study the effects of various Cabernet Sauvignon clones grafted onto different rootstock. This study matches 10 Cabernet clone types grafted on 10 rootstock types, with a total of 3,600 total vines planted in Lake County, California. The goal of the study is to look at how the interactions between rootstock and clone can handle the changing climate where drought tolerance may be key to a successful harvest and simultaneously producing high-quality Cabernet grapes. https://www.morningagclips.com/saving-cabernet-from-climate-change/

Ample Supply + Lower Demand = Good for Winemakers

The trend has been one that has been several years in the making . . . the 2019 California grape harvest is expected to leave a lot of fruit hanging. A combination of overly aggressive sales forecasts for the past several years combined with a bumper crop year in 2018, has had a synergistic effect that commercial demand for wine grapes in 2019 is much lower than usual. While this is not good news for some grape growers, hobby and small-scale winemakers may be able to find great prices on high-quality grapes. https://www.winebusiness.com/news/?go=getArticle&dataId=219681

The Maceration Accelerator

While this piece of news is really more for the bigger commercial winemakers, we thought it interesting enough to share with winemakers of all sizes. A new machine, the Della Toffola Maceration Accelerator or DTMA, reduces maceration time by up to 50% while simultaneously improving the extraction of polyphenols and anthocyanins. The maceration accelerator effectively shreds the skin of the grape while not shredding the seeds. The process known as Accentuated Cut Edge (ACE) maceration has been the focus of Dr. Angela Sparrow’s studies, helping lead to this new technology. For more on her research, you can visit:
