We use 18/10 stainless steel , the same metal that is used in the highest quality silverware. Joulies are manufactured in a factory that has been making silverware for over a century, so you can be sure it’s done right.
What is inside Coffee Joulies?
Coffee Joulies’ PCM absorbs the excess thermal energy from the coffee or tea through the breaking of its crystalline bonds , turning from a solid into a liquid while sealed inside the stainless steel shell. The PCM stays at a constant 60°C (140°F) during this process, until it becomes fully molten.
Are Joulies out of business?
The website of Coffee Joulies is still operational, but everything has been “sold out.” They are currently unavailable on Amazon. Both men describe their companies as “open” on their LinkedIn profiles, but Peleton has employed Petrillo since May 2019.

What is the specific heat of coffee?
The specific heat of green coffee was found to be around 1400 J/kgK at room temperature The thermal decomposition of dried green coffee was endothermic in the temperature range of 100–245°C with a peak at 120°C. This reaction was estimated at 100 kJ/kg having activation energy of 70 kJ/mol.
What is the value of specific heat of water?
For liquid at room temperature and pressure, the value of specific heat capacity (Cp) is approximately 4.2 J/g°C This implies that it takes 4.2 joules of energy to raise 1 gram of water by 1 degree Celsius.
What is the specific heat capacity of milk?
According to the The American Association of Cereal Chemists handbook, “Dairy-Based Ingredients” by Ramesh Chandan, skim milk has a specific heat of 3.97 J/g °C, whole milk has a specific heat of 3.89 J/g °C , and cream has a specific heat of 3.35 J/g °C.
Is coffee heavier than water?
The weight of one fluid ounce of water is about 28.4 g Brewed coffee has some solids and crema in it so a two fluid oz double won’t be 56.8 grams. But why 36 grams for 18 grams of coffee? Why not 45 grams?.
