Is guayusa a tea?

No. Guayusa (Ilex guayusa) is a different plant species. It is related to the holly and native to the Amazon rainforests. Although guayusa is no tea, it is prepared the same way. ‘Tea’ refers to a single plant species, the Camellia sinensis, originating from South-East Asia. Green, black and white teas are all derived from this plant; the harvesting and drying process determines the flavour of the tea. Guayusa has a naturally soft and mild taste.

Is there any risk of the presence of PAH (Polycyclic Aromatic Hydrocarbon) when guayusa is processed?

No. After having been picked and washed, the guayusa leaves are checked for quality and chemicals and then dried in the open air. Subsequently, they are carefully transported to our facility in Quito, where the final product is prepared using a gas oven at a controlled temperature. Our guayusa is not roasted or smoked - these are the processes that could cause the presence of PAH as is often the case in yerba mate.

Where does guayusa grow?

Guayusa grows in Peru, Ecuador and Colombia, in the upper course of the Amazon. The Amsterdamse Frisdrank Fabriek gets the leaves only from Ecuador, which is one of the most biodiverse regions in the world. In order to ensure that the guayusa is cultivated organically and sustainably, we only work with farmers who are inspected annually.

Which active ingredients does Nightwatch contain?

Guayusa contains a group of active substances called xanthines. These include caffeine, theophylline and theobromine. These same substances can also be found in coffee, tea, cocoa, mate, guarana and kola nut.
However, what makes guayusa unique is that it’s the only one that contains guanidine, a substance that induces a feeling of relaxation. It’s low in caffeine, lower than a cup of green tea; the energy is mainly created by the synergy between the different substances. The caffeine comes in bound form, which results in slow absorption. All these factors combined ensure a long-lasting energetic and pleasant feeling without highs or lows, without nervousness and palpitations like you would get from drinking coffee or other energy drinks.

What do the Indians use guayusa for?

To the Indians, guayusa is a sacred herb. The Quichua live to be very old and even in their eighties they are often fit and healthy enough to go hunting, even in a challenging environment such as the rainforest. They also use guayusa to stay awake and alert when they stand guard at night or to dance all night during rituals. Hence the name Nightwatch. It gives them the energy to start the day, go hunting and cultivate their gardens. Life in the Amazon is hard and intense and the Indians claim it would be impossible to survive without guayusa. Now we too can use their secret to conquer our own jungle and get and stay empowered while at the same time we help the Amazon and its inhabitants to preserve their environment and culture.

For whom is Nightwatch suitable?

For almost everyone: students drink Nightwatch to stay focused when they’re studying, entrepreneurs to get things done, sportsmen drink it to enhance their performance. Nightwatch is also an excellent thirst-quencher at parties and festivals. Our Nightwatch Bar can often be found at such events, enabling you to party all night in a healthy way without having to deal with a hangover the next day.
