It might be the center of winter, however Quails’ Gate Vineyard is bringing the warmth to its winery with infrared expertise.
The West Kelowna vineyard is testing an infrared vacuum LED tube to remain sustainable by the winter or perhaps a chilly snap.
“It’s a light source that produces more heat than light and the idea is to heat the vine itself rather than the air around it, above that critical freeze temperature,” mentioned Rowan Stewart, Quails’ Gate winemaker.
The expertise is anticipated to carry the vines about 6 C hotter than the encompassing air, which is important in avoiding bud loss.
“-24 C is usually where you would see 50 per cent bud death and after that it progresses pretty quickly to 100 per cent, so if you warm -25 C to -20 C you could save your harvest,” Stewart mentioned.

“I think we need to be really careful about the type of technologies we bring over because we’re a unique wine-growing region. I can’t think of many wine-growing regions in the world where it would be -25 C in the winter and 45 C in the summer,” mentioned Kullman.
