Dean,
I wonder also if the Megiolis aren't a higher quality juice. I have made both and think the Meg juices richer and more flavorful than the MEs but then I have only made red Megs. Whites may be different. As to the finished wines, it is too early to tell. Our oldest is only 10 months and I haven't bottled it yet.
And Ron, it may be worth knowing a little about our bias here at Put-in Bay. SWMBO prefers reds and rarely drinks white while I prefer reds most of the time but enjoy whites in the summer. So, I am inclined to spend more $ on red kits than white kits. Also, it seems to me that it is more difficult to make a good red out of a kit while the whites come out very well without much tweaking.Thus, giving ourselves the best chance with high quality(and higher $)juices for reds seems appropriate.
