Daily maximum and minimum temperatures, and precipitation, for the commercial vineyard in 2014 (A), 2015 (B), and 2016 (C) located in the Snipes Mountain American Viticultural Area in eastern Washington State, USA. Washington State University AgWeatherNet Snipes Mountain weather station was installed on 27 March 2014. (A) 2014 was considered a slightly-above-average temperature year, with consistent, low precipitation typical of the region. (B) 2015 was considered an exceptionally hot year, with a regional storm in late May which produced locally heavy rain. After that event, many of the remaining summer months (June, July, August, and September) did not have measurable precipitation. (C) 2016 was considered a relatively average year in terms of heat accumulation, with notable late-harvest rainfall for the region.

Total leaf area removed at the time of fruit-zone leaf removal indicated for (A) Vitis vinifera Cabernet Sauvignon, and (B) V. vinifera Merlot grown in the Snipes Mountain American Viticultural Area in eastern Washington State, USA. Error bars are standard error. Different letters denote significant differences among treatment means at α = 0.05 using Tukey’s honest significant difference test; lowercase letters are means separation within a variety for 2015; uppercase letters are means separation within a variety for 2016.

Sunburn severity on clusters, rated from the eastside and westside of the grapevine canopy for the specified timing of fruit-zone leaf removal in both (A) Vitis vinifera Cabernet Sauvignon, and (B) V. vinifera Merlot, grown at a commercial vineyard in the Snipes Mountain American Viticultural Area in eastern Washington State, USA. Average sunburn severity of clusters on the western sides of the vines are shaded gray, and average sunburn severity of clusters on the eastern sides of the vines are shaded black for easier viewing. Error bars are standard error. Different letters denote significant differences among treatment means at α = 0.05 using Tukey’s honest significant difference test.

Dormant pruning weights in 2014 and 2016 of (A) Vitis vinifera Cabernet Sauvignon, and (B) V. vinifera Merlot vines that underwent fruit-zone leaf removal at different times. Vines were in a commercial vineyard in the Snipes Mountain American Viticultural Area in eastern Washington State, USA. Error bars are standard error. Leaf removal treatments did not statistically influence dormant pruning weights for either variety in the two years it was evaluated.
