Yea makes sense, I've bought juices that have reviews saying the best juice I ever had , and then I get it and I have to suffer through the bottle because I can't stand wasting money haha, like jam.momster, oh my God I hate jam momster all of them, it taste like cough syrup to.me.
I got two different juices from two different original mixers. Both were allegedly 'cut' with real booze. The one tasted very professionally done. The flavor of the whiskey was there for sure, but it didn't over power the whole of the juice, it was a nice mellow blend. The other was well pure excrement.
Grew up in a family of alcoholics, so it doesn't take much for me to be a 'boozehound'. I do not drink seriously any longer. I simply cannot, oh I could, but life dictates otherwise. That's how and why I know of tasting a difference between a pro mixer and someone just fumbling to make a buck.
A pro can mix whatever, maybe second or third try they got it. Found that out while tending bar in a Moose lodge. Alcoholics are forgiving a time or two, drunks aren't, drunks don't get served either. Yes, there's a vast chasm of difference. If you cannot tell, you don't tend bar.
