For most of the 20th century before the early 1970s, the only northern Rhône wine well-known far from the region was Hermitage, and there was little demand on the export market for Rhône wines. Producing wine from hillside vineyards requires more labour than on flat vineyards, and is therefore economically difficult when demand and prices are low. This was particularly felt by some Rhône appellations in the early post-World War II era, including Condrieu and its neighbour Côte-Rôtie, with the 1950s and 1960s a particularly difficult time. Rhône wines in general started to be more in demand from the early 1970s, and stronger so from the late 1970s/early 1980s. From this time, the négociant business of Marcel Guigal at Ampuis was important in expanding the market for Condrieu wines. Guigal primarily made his name with his Côte-Rôtie wines which then paved the way for his bottlings from other appellations, which also includes a significant portion of white wine. Guigal's Condrieu was sourced from small growers in the appellation.
