As a number 22 bus approached while we were strolling along Piccadilly, Margaret Humbrecht recalled that it would be 30 years next year since she spied her future husband, Olivier, on the 22 London bus in exactly the same spot. She had made a beeline for the tall, shy French winemaker and the result has been an entente très cordiale of Alsace and Glasgow ever since. 29 years on, the Humbrechts were back in town at 67 Pall Mall to show off the their wines from the 2014 vintage.
