Best "Make It Yourself" Classic Kool Aid Flavor

It's been over 2 decades since I've made any kind of Kool-Aid but the answer is Grape. There is only Grape.

Onion flavored.

I used to take 2 liter soda bottles and make the ice blue(blue-raspberry) kool-aid all the time as a kid. Just typing this makes want to do it right now. I also find it amusing that raspberry flavored stuff is often relegated to being blue to make it distinct from cherry and strawberry.

Last summer I had a craving for Orange Kool-Aid, so I got a few packets of various colors. On a hot day a tall glass, full of ice, and filled up with Kool-Aid cannot be beat.

Haven't had kool-aid since I was a teenager. But yeah, red or grape is the only flavors that matter and orange is one of the worse if I remember correctly. Still good enough to drink, but bottom tier.
