British chocolatiers are grappling with the dual challenges of soaring cocoa prices, which have risen by 50% due to a record high before Easter, and a projected 11% decline in global cocoa production attributed to climate change. With 75% of the world's cocoa originating from four West African states, there are concerns that climate change could significantly reduce the cultivation area within the next two decades. To cope with these cost pressures, chocolatiers like Niaz Mardan of Sandrine Chocolates in London are reluctant to increase prices, while some manufacturers are opting to reduce product sizes or substitute cocoa butter with less expensive alternatives. Additionally, there's a growing trend towards chocolate bars filled with other ingredients, a strategy that may become increasingly popular as cocoa prices continue to escalate.
