The vineyard sits in the Kootenay River Valley, about 30 mi. from the Columbia River. The climate is influenced by a strong Pacific flow. The annual precipitation is 22". The winters are cloudy and relatively tempered for being this far inland. The winter minimum has not dropped below -19C since we have been monitoring it. The springs are slow to warm, but quite frost free. Our growing season is about 170 days. The summers are warm but not overly hot. This site would get very few days over 37C. Because of our latitude (49 degrees N) and long days we regain ten days of growing time compared with Napa,Ca. The growing degree days for this site are 1,200 hrs. based on the Celsius scale. The average budbreak is April 26 and the average harvest date would be from early Oct. for whites and around Oct. 16 for pinot noir.
The soils range from a sand/clay to gravely decomposed granite. The soil has excellent drainage, and has high minerality, with calcium, manganese, magnesium, and iron being at their maximum level. The soil has good water retention. There is no irrigation after the 2nd. year of the vines age. The yields are very low and have been around 1.5 tons per acre.
