Brew, press, sip and enjoy all in the convenience of a single brew and go Infuser Mug! The double-walled, vacuum-insulated, restaurant-grade stainless steel construction of the Infuser Mug gives it phenomenal insulation properties and incredible durability, making it a very versatile and low maintenance travel companion. Designed with a fine mesh filter and patented infusion-stopping chamber, the Planetary Design Infuser Mug brews a perfectly clean cup of tea without the worry of over-steeping which can cause bitterness . Once the plunger is pressed, the tea leaves are compressed into a solid chamber and away from the water. The Infuser Mug also works great for making your own cold-brewed coffee or fruit infused water. Simply place a few scoops of coffee grounds or fruit pieces, fresh mint, basil, cucumber, etc. into the infuser basket. Pour clean filtered water into the mug, and let steep in the refrigerator overnight. The result is a customized, deliciously smooth cup of cold brew or healthy fruit-infused water, ready to go wherever you go! Planetary Designs Tea Tumbler 102442
