Joy (in my opinion and in small doses) reminds me of fried bread, like deep fried donuts, funnel cake - those sorts of things. It's sweet, but not candy sweet. It's good in bakery type juices like cake, muffins, donut, etc. Some, however, get the taste of "stale beer" from it. If you're gonna order it, get the smallest amount possible to try as opinions are pretty divided. You either love it or you hate it, no in between.
Scales are awesome for mixing. Your measurements are more precise and there's a lot less cleanup than with using all those syringes and droppers. You can mix right into the bottle or if you're clumsy like I am, you can mix into a small cup, or whatever else you're comfortable with, and pour it into your bottle(s). They're available for very little expense on Amazon and eBay, less than $20, depending on what kind you get. It is advised to get one with at least a .01 graduation.
