Supplemental Figure 1  Hourly average ambient photosynthetic active radiation (PAR) and air temperature (A, B), monthly average ambient PAR and air temperature during 800 to1330 hr and 1330 to 1800 hr (C, D), and percent time spent at 25% increments of the seasonal (1 June to 28 Oct) and postverasion (15 Aug to 9/19 Oct 2013/2014) PAR ranges during 800 to 1330 hr and 1300 to 1800 hr (E, F) in 2013 (A, C, E) and 2014 (B, D, F). Data logged every minute from 1 June to 28 Oct.

Supplemental Figure 2  2013 Cabernet franc berry temperature on EAST (A, B, and C) and WEST (D, E, and F) canopy sides in AM (A and D), NOON (B and E), and PM (C and F) as affected by leaf/lateral removal (NO = no removal; MED and HIGH = post-fruit set removal to medium and high extents, respectively; P-B = pre-bloom removal). AM = 0900 to 1030 hr; NOON = 1245 to 1415 hr; PM = 1545 to 1715 hr. Data points are an average of six berry temperature measurements; n = 6. Error bars are +/- standard error.

Supplemental Figure 3  2014 Cabernet franc berry temperature on EAST (A, B, and C) and WEST (D, E, and F) canopy sides in AM (A and D), NOON (B and E), and PM (C and F) as affected by leaf/lateral removal (NO = no removal; MED and HIGH = post-fruit set removal to medium and high extents, respectively; P-B = pre-bloom leaf removal). AM = 0900 to 1030 hr; NOON = 1245 to 1415 hr; PM = 1545 to 1715 hr. Data points are an average of six berry temperature measurements; n = 6. Error bars are +/- standard error.

Supplemental Figure 4  2013 Petit Verdot berry temperature on EAST (A, B, and C) and WEST (D, E, and F) canopy sides in AM (A and D), NOON (B and E), and PM (C and F) as affected by leaf/lateral removal (NO = no removal; MED and HIGH = post-fruit set removal to medium and high extents, respectively; P-B = pre-bloom leaf removal). AM = 0900 to 1030 hr; NOON = 1245 to 1415 hr; PM = 1545 to 1715 hr. Data points are an average of six berry temperature measurements; n = 6. Error bars are +/- standard error.

Supplemental Figure 5  2014 Petit Verdot berry temperature on EAST (A, B, and C) and WEST (D, E, and F) canopy sides in AM (A and D), NOON (B and E), and PM (C and F) as affected by leaf/lateral removal (NO = no removal; MED and HIGH = post-fruit set removal to medium and high extents, respectively; P-B = pre-bloom removal). AM = 0900 to 1015 hr; NOON = 1245 to 1415 hr; PM = 1545 to 1715 hr. Data points are an average of six berry temperature measurements; n = 6. Error bars are +/- standard error.
