I have eaten the last of the New Zealand Lemonade. During the season I sampled fruit that was mostly yellow mature fruit (still some green rind), completely yellow fruit, and one I found just two days ago that had dropped from the tree and was just slightly turning soft. I don't actually know how long ago it fell to the ground. Least sweet = the early mostly yellow (still some green rind), next in sweetness = completely yellow fruit, and the fruit with the highest sweet taste was the fruit I found that had dropped from the tree. Therefore, it made me think that perhaps storing the NZL much like one does with a Dekopon, might be the way to go if higher sweetness is desired..
