I'm chewing back my own words, but this afternoon I left a bottle in my pocket, and a bottle in my arm rest today. Temps were in the upper 90's. Windows were cracked, and sunroof slightly open to allow a somewhat even test. Both out of sunlight but direct outdoor temps. Both of my juices tasted better than what they did last night.. The breakfast waffle definitely improved. The flavors blended much better together.. Not going to lie, might have found the last step to the steep process: a few hours in the car. Now just waiting for the VG to go back to it's natural viscosity, and not a runny liquid.
