TANAT is a Paris roaster with a light, transparency-focused roasting style. Lucid 2.1 was developed with APAX LAB as a water profile matched to that style: rather than adding weight or sweetness, it is built to sharpen definition and let origin character separate out clearly in the cup.

What the profile is aimed at

APAX describe the target as clarity and separation of flavour, a precise aftertaste, and a bright, lifted cup. In practice that makes it a better match for washed and light-roasted coffees, where the point is articulation rather than body. If your coffee is already delicate and you want more of it, this is the direction. If it tastes thin and you want weight, KONFLUX or JAMM are the relevant profiles instead.

How it differs from the core APAX range

Two things stand out. First, it is a finished recipe rather than a building block: there is nothing to blend, only a dose to set. Second, the formulation is magnesium-led and includes magnesium sulfate and magnesium citrate, with no calcium salt in the ingredient list. Sulfate is generally associated with perceived brightness and aroma separation, which lines up with what the profile is aiming at. It also explains the lower dose rate: 1.5 to 2.5 g/L here against 3 to 4 g/L for the core concentrates.

How to use it

Shake the bottle thoroughly before use. Either dose 1.5 to 2.5 g per litre of distilled or demineralised water for a full brew setup, or add 1 to 2 drops directly into a finished 200 mL cup, which is the easiest way to taste the effect side by side against an untreated brew. APAX state the concentrate is not intended for direct consumption in undiluted form, and that it should not be used inside espresso machines. Dosing into the cup after extraction is fine; putting mineral-loaded water through a boiler is not.
