I say yes. I too am a beer brewing no secondary brewer (usually), and I also made an Island Mist kit for the wife and her friends. And yes, you really ought to use at least a secondary and possibly a tertiary vessel for wine. Even this wine.
I think I used 3 vessel total, including the primary bucket and two rackings to a carboy. The kit says you don't have to wait too long for these wines, but I thought a couple of extra months made a lot of difference in taste anyway.
The wine turned out pretty good, BTW, but I think next time she will prefer something a little stronger after all. We did the Sangria and it's got a lot of fruit flavor and I didn't use all of the sweetener either. IMO it would be best over ice.
Day after day, it reappears. Night after night my heartbeat shows the fear. Ghosts appear and fade away. Come back another day.
