All but one of the sub-indices closed the month in positive territory. The Burgundy 150 was this month’s strongest performer, gaining 1.5%. The Champagne 50 index also performed well, climbing 1.3%. With several recent releases in the market, Champagne has seen high levels of trading activity in September: the region accounted for 10.7% of all trade by value.

Only the Rhone 100 index continues to drift: it is the only sub-index in negative territory over one year and closed September down 0.3%.
