I just brewed a belgian strong golden-ended up 10%. At bottling (after about 3 weeks in primary) I added an oaked chardonnay to some of it at the rate of about 330ml/gallon. My younger brother, who swears by St.Bernardus Abt 12, cannot get enough of this beer. It ended up less sweet than Abt 12, and of course lighter in color. But the wine gives it a very unique taste. Just enough to make you ask, "what is that?" Very pleasant. Also did the same thing with a belgian blond. Great result as well. Next best thing if you don't have a barrel.
