Hi Jimmy, great video as always. I just want to provide an alternate explanation to the sun impact in relation to angle. Your explanation that distance is significant but the additional spread of rays with increased angle dilute the sun ray density.

[@WineWithJimmy]

Hi Jonas - you’re correct the diffusion over a greater surface area and distance is the reason. L3 only states distance hence why it is only mentioned here. In my L4 video I discuss the angle, diffusion and distance

Hello Jimmy, your comments about latitude and temperature were incorrect. You stated that the reason its cooler away from the equator is that the sunlight has to travel further but in fact it is because the suns energy is spread over a larger area due to the angle the light is hitting the Earth. More direct at the equator hence the hotter temperature. Aside from that, amazing videos Jimmy! Thank you

Hi Dan - thanks for your comment - if you are referring to slide 14:28 onwards I am not referring to temperature (heat) as you mention but to sunlight - they are not mutually exclusive, but I do not want to mention heat/temperature here. But yes you are correct regarding the angle, but WSET only state distance, hence why its been simplified here. Keep the comments rollin'

Great channel Jimmy, come here quite a bit, and first time on this video. Agree with these comments re angle as the primary reason why latitude affects sun exposure. The difference between the higher and and lower latitudes re time that light has to travel is less than a tenth of a second.

Thank you Jimmy

Many thanks!

Wa Hi...
Thnx a lot Jimmy

My pleasure

I got silly questions. The facing of sunlight only works if the vines planted on the slope right? Vines planted on flat surface will expose to all direction of sunlight?
