European wheat futures rose as a weaker euro and gains in Chicago futures lent support to prices. December milling wheat on the Paris-based Euronext exchange was up 0.25 euro or 0.15 percent at 171.50 euros a tonne. Trade was thin due to a public holiday in parts of Europe. The International Grains Council lowered its forecast for European Union production in the 2017/18 season by 0.4 million tonnes to 149.9 million tonnes. The revision was mostly due to a 1 million tonne cut in output for Spain, although higher production in France, Germany, Romania and Britain helped offset the bulk of the decline.
