You can put coffee in your stainless steel water bottle! Whether you choose the narrow-mouth or wide-mouth model, Iron Flask water bottles are designed for ultimate convenience. The vacuum-insulated stainless steel is safe for both hot and cold beverages, including coffee. The double wall of insulation will also maintain hot temperatures for hours.
Please keep in mind that if you add any dairy products or milk substitutes to your coffee, make sure to clean and sanitize your bottle after use as soon as possible. If your bottle goes unsanitized for longer than 20 minutes after use, we recommend using any of the cleaning methods of hydrogen peroxide, water cleaning tablets, or bleach solution.
