100% agree. Thats where you have to be careful mixing. You add enough flavors that contain EM or MM and you wind up with a juice with virtually no taste. All flavors have a maximum level. In other words if strawberry ripe tops out at 8% and you add 10% you just partially muted some of the flavor. Now stack another flavor that contains the same molecules and you mute it more.
Yep- you get it. EM/Maltol is just one (very common) example of a good molecule that can go bad when used in excess. In another thread I said that mixing is like making perfume, and I'll stand by that statement. juice is about the sense of smell, and the line between the smell of flowers and the smell of feces is a fine one.
Really good complex juice is probably juice that skirts that line successfully.
