Keeps your coffee the right temperature, and when you’re ready to pour, an intuitive hinge on the lid locks in place when open.


Good to Know

Madcap is proud to join 1% For the Planet, a global organization that exists to ensure our planet and future generations thrive. We’re committing to donate 1% of our annual sales to support nonprofit organizations focused on the environment, climate change, and water conservation. To kick things off, we’ve partnered with Traverse City based FLOW (For the Love of Water) on our latest seasonal blend: Lake Effect. FLOW is dedicated to ensuring the waters of the Great Lakes Basin are healthy, public, and protected for all. As coffee obsessives we at Madcap are no strangers to the importance of good water, and as a proudly Michigan based company we hold the Great Lakes near and dear. That’s why we’re donating 10% of Lake Effect sales online and in café to FLOW’s mission.
To celebrate the partnership we’re launching the Lake Effect Collection. This limited-edition capsule collection features custom, hand drawn designs by artist and Michigan-native Geoff Holstad. Including a range of water bottles, coffee tumblers, apparel, and headwear, all Lake Effect merchandise is available exclusively through Madcap’s website.
