European wheat futures edged lower on Wednesday as a firm euro and rising estimates for harvest supply in the Black Sea export region curbed support from higher US prices. December milling wheat on the Paris-based Euronext exchange settled 0.75 euro, or 0.5 percent, lower at 161.75 euros ($192.95) a tonne. The Euronext benchmark had risen in the previous session, extending a recovery from last week’s contract low of 156.50 euros, as buyers sought to lock in relatively attractive prices.
