This is the culmination of many months' work (and an ongoing project). I hope you find it useful.
On this map, you'll find locations for most every flavor I can produce, with the exception of a few left off due to their inconvenient location. Some flavor spots are very small (as small as a single coordinate, though they're not bound to coordinates), and there is a chance you may not get the flavor in a vineyard you build nearby.
I have listed the flavors by highest tier (meaning "Hazelnut" rather than "Nuttiness," for example). If you have problems getting the full flavor, try using a different vine, or try slightly altering your tending so you get different end stats. If this does not make sense to you, or you need more information, please see the links at the top of the page.
Enjoy!
I've left in the physical locations of my private vineyards to aid any hunters who get stuck with a Vision on a vineyard of mine...That task will be tough enough as is. >.<
I'll tried to keep it complete, but sometimes I run out of time.
