OLIVER, British Columbia — Jackson-Triggs Okanagan Estate Winery began Tuesday night what is believed to be the region’s earliest harvest of vinifera grapes in the history of British Columbia wine.
Harvest for the Oliver winery started with Sauvignon Blanc from its estate Bear Cub Vineyard in Osoyoos, just north of Oroville, Wash. Constellation Brands representative Lori Pike-Raffan said the B.C. Wine Institute in Kelowna reports Aug. 27 marks history.
“I spoke with the BCWI, and they confirmed that this is the earliest harvest ever for vinifera table grapes in the Okanagan since they’ve been keeping records,” Pike-Raffan said.
Jackson-Triggs white winemaker Derek Kontkanen pointed to lower-than-normal precipitation and above normal Growing Degree Days as the factors in the record start.
“This is my 10th vintage here and it’s great to see a return to more normal Okanagan-like weather, similar to 2008 and 2009, with a warm and consistent growing season,” Kontkanen said in a news release. “When looking at the numbers, so far this season is shaping up to be a very good vintage. The flavour profile of our first varietal to come in Sauvignon Blanc, is just what we’re aiming to achieve — grassy, grapefruit and tangerine tropical notes, along with good balance of sugar and acidity.
“Now we just need the weather to hold out to the end of October,” he added.
The GDD calculation helps predict important phenological stages for grapes such as bloom, veraison and crop maturity.
Troy Osborne, Constellation’s director of viticulture for its western properties, said, “The growing season to date, to sum it up in a few words — hot, dry, phenomenal. In my 21 years here in the Okanagan in viticulture this is the earliest we’ve ever picked vinifera grapes.”
Crop load for the Sauvignon Blanc came in at a relatively small 3.5 tons per acre, the winery reported.
Bear Cub Vineyard was first planted in 2000 along the Osoyoos Lake Bench. It spans 186 acres and includes Cabernet Sauvignon, Chardonnay, Merlot, Viognier and Syrah.
Data collected by Constellation for its British Columbia vineyards showed temperatures during July surpassed 102 degrees Fahrenheit (39 Celsius), which pushed up verasion by as much as 10 days.
