First, Coffee Joulies quickly cool your coffee or tea to the perfect sipping temperature so you'll never burn your tongue again.
Next, Coffee Joulies gradually release the heat back into your hot beverage, keeping it in the ideal temperature range longer.
Food-grade phase change material sealed inside a thin, polished stainless steel shell, Coffee Joulies absorb heat from your coffee or tea, quickly cooling it to the perfect temperature. The stored heat is slowly released as you drink, giving you extra time to enjoy your favorite hot beverage.
Made in the USA
Coffee Joulies are made in central New York in the old Oneida silverware factory owned by Sherrill Manufacturing. We spent eight months converting one of their century-old production lines to make Joulies, helping them come out of bankruptcy & create jobs in an area hit hardest by overseas manufacturing.
