Passage: Still wines from the Champagne region were known before medieval times. The Romans were the first to plant vineyards in this area of north-east France, with the region being tentatively cultivated by the 5th century. In fact, cultivation was initially slow due to the unpopular edict by Emperor Domitian that all colonial vines must be uprooted. When Emperor Probus, the son of a gardener, rescinded the edict, a temple to Bacchus was erected, and the region started to produce a red, light, and fruity wine that contrasted with heavier Italian brews often fortified with resin and herbs. Later, churches owned vineyards and monks produced wine for use in the sacrament of Eucharist. French kings were traditionally anointed in Reims, and champagne was served as part of coronation festivities. The Champenois were envious of the reputation of the wines made by their Burgundian neighbours to the south and sought to produce wines of equal acclaim. However, the northerly climate of the region gave the Champenois a unique set of challenges in making red wine. At the far extremes of sustainable viticulture, the grapes would struggle to ripen fully and often would have bracing levels of acidity and low sugar levels. The wines would be lighter bodied and thinner than the Burgundy wines they were seeking to outdo.
