Brew Water, Perfected — With Apax Lab Mineral Blends

Apax Lab is a set of mineral blends designed to improve how your coffee tastes. Each formula helps unlock different aspects of flavor — like clarity, sweetness, or florality — by adjusting the water you brew with.

* Apax Lab is not flavouring, each blend is a composition of minerals that naturally exist in water.

A cup of filter coffee consists of more than 98,5% water. The mineral-composition of the water that was used to brew the coffee has a vital impact on the final taste of the coffee - Apax Lab is a mix of dpre-blended mineral-compositions that help to achieve a balanced brew by affecting the hardness, alkalinity and mineral-composition of your coffee.

You don't need to use distilled or RO-water to use Apax Lab, you can add a few drops to your standard brew-water, or directly into your brewed coffee and notice a significant improvement. However, to reach the highest potential of your coffee, we recommend using distilled or RO-water, as it will give you full control of the mineral composition.

Regular tap water, bottled water and spring water already have lots of minerals dissolved in them, which gives less room for the Apax drops to have effect, as you risk increasing the hardness of your brew water if you add too much Apax minerals.

Each Apax blend is designed to enhance different characteristics of your coffee:

• TONIK Brings out acidity, brightness and a juicy character
• JAMM Brings out sweetness and mouthfeel
• LYLAC Brings out floral characteristics and a silky finish.
