In this video, Joanna Simon explores the notion of terroir in Alsace: the combination of climate, soil, producer and location which makes every wine an expression of a sense of place. Joanna meets two Alsace producers -- Frédéric Blanck from Domaine Paul Blanck and Paul McKirdy from Domaine Zind-Humbrecht -- to find out just what influence their different vineyards have on the wines they make.
