Humidity Halts Chocolate Production Amid Heatwaves
30 Jul
Summary
- High humidity, not just heat, is disrupting chocolate making.
- Summer sales are impacted as products melt and cannot be shipped.
- The company is exploring solutions like extra air conditioning.

Isabelle Chappelle, owner of Chocolat Chocolat near Gamlingay, Cambridgeshire, has been forced to pause some production because of ongoing high humidity levels. While heatwaves typically disrupt chocolate making during the hottest parts of the day, Chappelle noted that humidity poses a greater challenge. This has led to a significant impact on summer sales for items typically bought for birthdays and graduations. The company, which sources Belgian chocolate from France, has had to implement freezer packs for deliveries and store most of its stock in an air-conditioned room. Imports have also seen a decrease, with deliveries needing careful inspection upon arrival. The situation also affects the sampling of autumn products, delaying new developments. Chappelle is now considering investments in extra air conditioning and adjusting production to earlier in the season, including increased stockpiling.
The company's operations, including its shop in Cambridge, have been significantly affected by the weather. The inability to ship products in time for events like graduations has directly harmed revenue. Furthermore, the seasonal development of new products for autumn and holiday seasons is being hampered. To combat these issues, Chocolat Chocolat is evaluating long-term solutions to ensure business continuity despite challenging climatic conditions. The focus is on adapting their manufacturing and storage processes to better withstand high temperatures and humidity.
