A serious question discussed in the Figaro newspaper a few days ago by the reporter, Sandrine Cabut. She told of a serious and detailed study undertaken by Swiss doctors to work out what drink made a fondue more digestible.
On the one hand, (white) wine, on the other, (black) tea, with or without a swig of kirsch.
You could have knocked me down with a feather, as I learned that fondue consumed with tea took 6 hours to be half digested, whereas with wine it took 9. Thus alcohol had apparently slowed down digestion considerably... But do take heart, those who had drunk wine + kirsch did not suffer stomach burns or feel bloated any more than the others...
Conclusion ... fifty-fifty: unless you have digestive problems, you can drink whatever you want with your fondue!
A resolution for the New Year perhaps!
