The '''{{PAGENAME}}''' is a test conducted by Cranialwizard consist of the question of whether or not a player may take a sprout from a blue grape bush in the southern hemisphere and plant it in the northern to grow blue grapes, or the opposite, taking a green grape sprout and planting it in the southern hemisphere to grow green grapes in a naturally blue-grape area. This is the general information that the Wurm public and the wiki has released:
"Blue grapes are harvested from [[grape|grape bushes]] in the southern half of a map. They are used in creating blue grapes [[juice]] for making red [[wine]]."
