So how do you know it is good? You look at it. It is translucent red with hints of violet. it looks appealing. You take in its aroma and it smells of bright red fruit. raspberry and currant with a hint of cinnamon. You draw it to your lips and it just plain feels good. and then the flavor dance begins. There is a completeness that can't be described in words. You know it when you smell it, when you taste it and especially when you feel it.
