Coca-Cola Co. is to increase the price of its orange juice brands in the US for the fourth time this year ahead of the smallest Florida orange crop in 20 years.

The US soft drinks giant said wholesale list prices for its Simply Orange and Minute Maid Premium brands will rise by up to 11% this month.

The US Department of Agriculture estimates that the 2006/07 orange crop will reach 135m boxes, a forecast below industry expectations.

"The crop report - with accompanying increased futures and fruit prices - has driven the need for additional price increases," said Mike Saint John, Minute Maid general manager at Coca-Cola North America.

Saint John said the company would continue to sell juice at a "fair market value". He added: "We'll continue to invest aggressively in innovation and demand creation to help drive category and industry growth."
