Let me narrow this down for you- You can either till it in when you till again, or rake it up and get rid of it!
Did that clear it up for you?
Actually it doesn't make a lot of difference. As long as you used Roundup to kill it for tilling, it really doesn't make any difference at all. If it is definitely dead, it won't hurt to leave it there, but it doesn't look as neat laying there.
At the wine tasting, it isn't surprising you didn't care for the LaCrosse if it was dry. A number of the white hybrids are very good if made correctly and harvested at the right time. In your area, if you let them hang too long, the acid levels get too low and they lack a good balancing acid. They also need just a bit of residual sugar to bring the fruitiness out. If there isn't enough acid then they are too sweet. They need to be picked when pH is about 3.1-3.2 and TA is about 0.9- 1.1 g/l. The touch of residual sugar(1.002-1.004) balances this higher acid and leaves them crisp and fruity.
LaCrosse doesn't have quite as much flavor as some of the others. From what I have done St. Pepin(apricots and apples), ES 6-16-30 (pineapples), Petite Amie and LaCrscent (both very fruity and crisp) all have more flavors than LaCrosse.
Where you are for reds, you have a lot of choices- how about St. Croix, Noiret, and Corot Noir. If you want a bit higher acid one to work with, there is Frontenac.
