In 1979, Jon Winroth began writing in French as well as English. He was invited to speak on his technique of long dialysis and long intervals between dialyses (the contrary is the rule) at a meeting of the National Kidney Foundation by Professor Robert Swenson of Stanford University. Gambro kindly paid for his trip, Prof. Swenson put him up and another nephrologist offered free dialysis. Between the sessions of the meeting and the obligatory dialysis sessions, he found time to see 17 top California wine-makers. Returning with 13 bottles in his luggage, he sneaked out the "Nothing to declare" exit unquestioned. These 13 bottles were tasted at a memorable meal at the Trou Gascon, Alain Dutournier's early restaurant, and Jon Winroth's following article in "Lui" contributed to the increasing interest in California wines among French wine lovers.
