1 of 9

Similar in their South American origins and long-standing cultural significance, Guayusa and Yerba Mate share the essence of tradition and history. Both infusions offer a gentle, sustained energy lift, which is characteristic of their caffeine content.

However, it's in their differences that Guayusa truly shines. The main difference in effect is that Guayusa provides a stronger and more prolonged, smooth focus than Yerba Mate, while Yerba Mate gives more of an adrenaline spike. Additionally, while Yerba Mate is known for its bitter and earthy flavour profile, Guayusa stands out with its smooth, naturally sweet taste. Moreover, Guayusa's unique blend of ingredients, rich in antioxidants and essential amino acids, provides a longer-lasting, jitter-free energy boost, setting it apart from its counterpart. This exceptional combination not only contributes to its sustained wakefulness but also makes Guayusa a standout choice for those seeking both a flavourful and healthful herbal infusion experience.

What is Watt Water?

Watt Water is an energy drink that comes in a cube format which, when added to water, transforms into a delicious energy drink. It's designed to provide sustained energy and focus. Its active ingredient is Guayusa which provides a smooth & natural energy experience without the jitters and crashes of traditional energy drinks.

How does Guayusa contribute to Watt Water's energy effects?

Guayusa has unique benefits. Unlike caffeine on its own, guayusa provides sustained energy without jitters or crashes thanks to its unique chlorogenic acid profile which enables a gradual caffeine release, promoting lasting smoother, sustained energy and focus.

Serotonin (the "happy hormone") is elevated to levels that are 2-3x higher than those from coffee. Higher serotonin levels can positively influence decision-making by improving mood, reducing stress, enhancing cognitive function, boosting confidence, regulating emotions, and facilitating better social behaviour, all leading to better choices.

What makes Watt Water eco-friendly?

A dry cube format, rather than shipping cans or bottles, is ultimately more energy efficient due primarily to size and number of drinks that are in a pack. Think of it this way: while it takes 1 truck to transport a million Watt Water drinks, you need 20 trucks to transport the same amount of canned energy drinks. That's 20 times more CO2 emissions. Also, though cans themselves aren't made of plastic, plastic is wrapped around each shipping pallet and each individual 12-can tray when transported to stores or warehouses.

As a result, using cubes like this leads to 81% reduction in CO2 emissions and >95% reduction in plastic (during transportation), or >99% reduction if compared to drinks that use plastic bottles.

Our Guayusa is organically farmed and fair trade. Our packaging is a single material plastic that can be recycled an unlimited amount of times.

Is it really sugar-free and without calories?

Absolutely! Watt Water is completely sugar-free and has zero calories. We understand the importance of offering a healthier hydration option, and that's why we've crafted Watt Water to provide the refreshing taste you love without any added sugars or unwanted calories. Our focus is on delivering a clean and pure hydration experience that aligns with your health and wellness goals.
