Since I bought a Soda Siphon I wanted to get something to go with it, so I bought this 4-year-old Kool-Aid flavor. Don't worry about the expiration date because it is still 90% drinkable. But just in case I would check the package and the powder. The flavor isn't too special, it just tastes like a less strong tropical punch. But I thought It was clever how they had the powder change color, the powder will be red if it isn't wet, then when you add water I'll change blue. Red (powder), White (water), Blue (once the powder gets wet). I'll be saving some packets for the 4th of July just to make the holiday a little more special. And once I get my Soda Siphon I'll see if the CO changes the flavor a bit.
