With cocoa prices rising, will that chocolate bar cost more?

Since the price of a ton of raw cocoa on the London commodity exchange recently climbed to a record high of just under €5,500 ($5,960), chocolate fans have reason to be alarmed.

Just a year ago it was €2,500 and last month it was €4,000.

"A kilo of cocoa is almost €3 more expensive than it was a year ago," a spokesman for the German chocolate manufacturer Ritter Sport said.

"Anyone can work out for themselves what this means for the production costs of a 100-gram chocolate bar, which contains between 35% and 70% cocoa, but we are currently assessing the situation as a whole," he said.
