Well...I was definitely right...I did learn something from this thread!
After you guys commented, I went back and reviewed the posts.
For some reason I was thinking that Yooper was saying that she didn't see a problem splitting a 6-gallon batch between two 5-gallon carboys.
But, in truth, what she really said was two 3-gallon carboys, which of course, makes perfect sense.
So...What I have learned from this thread today, is that I CAN'T read!!!
Sorry I wasted your time with my blunder!
Rick - Thanks for the comment! Not having used a kit yet, I can see the benefit to topping-off with a similar wine, just to replace the tastings from the gravity samples, if nothing else, huh?
So, I really have learned something new today after all, thanks again!
