JAMM is the APAX LAB profile to reach for when you want a coffee to feel sweeter, richer and more rounded. It can help emphasise perceived sweetness, build body and soften cups that feel thin, sharp or lacking depth.
Think of using it like adding just the right amount of sugar and a pat of butter to a dish: not adding a new flavour, but helping the existing elements feel fuller, rounder and more connected.
What does JAMM do to coffee?
The profile brings out these qualities from your cup:
- Perceived sweetness
- Richness and depth
- Body
- Creamy, rounded mouthfeel
- Balance
- Longer, more generous finish
Signs that your coffee could benefit from the addition of JAMM
- Your coffee lacks sweetness or depth – If your coffee feels a little underwhelming and isn't quite sweet enough, JAMM can help emphasise sweetness and subtly create a deeper sensory presentation.
- Your coffee feels thin or light in the mouth – JAMM can enrich it by building a fuller body and more satisfying mouthfeel when your cup feels too watery or lacks weight.
- You taste overpowering acidity or bitterness – If your coffee's acidity or bitterness is too sharp or overpowering, JAMM can help neutralise it, creating a more balanced taste.
However, like any ingredient, it's crucial to use JAMM in moderation. Overuse can lead to undesirable effects.
What happens if you use too much JAMM?
More JAMM does not automatically mean more sweetness. At higher concentrations, the cup may begin to feel overly heavy, muted, dry or chalky, with less of the contrast that makes the coffee feel lively.
- Flattened Flavor - Excessive JAMM can mute the acidity that gives coffee its lively taste, resulting in a flat cup profile.
- Unpleasant Texture - Overuse can cause a certain dryness, chalkiness, and powderiness, detracting from the overall enjoyment of the beverage.
- Heavy Body - Too much JAMM can make the coffee's body feel too heavy, overwhelming the palate and making the coffee less refreshing.
We recommend starting conservatively and tasting the result first, before adjusting gradually.
What coffees work well with JAMM?
JAMM is a versatile mineral concentrate that is best suited for a variety of coffee types:
- Naturally Processed Coffees: This method, involving drying the coffee cherries in the sun, tends to produce coffee with more fruit and wine flavours. JAMM can amplify these characteristics.
- Coffees from South America and South East Asia: These regions produce a variety of flavours, from the chocolatey and nutty notes of Brazilian coffee to the fruity and floral profiles of Colombian coffee. JAMM helps highlight these distinctive regional characteristics.
- Fermented Coffees: Fermentation can enhance the inherent sweetness in coffee beans. JAMM can elevate this sweetness to new levels. This includes honey-processed coffees, where some of the fruit is left on the bean during drying, or coffees fermented with yeast or bacteria to create unique flavours.
Our general recommendation is to try it with any coffee where the sensory goal is more sweetness, depth and weight.
How to use JAMM: Pre-Brew or Post-Brew
Pre-brew: Add JAMM to your brewing water when you want to build sweetness, depth and body into a repeatable water recipe. We recommend starting with 3-4g/L of mineral concentrate in your brew water.
Post-brew: Add 1-10 drops directly into your coffee (200ml standard cup). We recommend adding a small amount of JAMM directly to the finished cup, stir, and taste before adding more if needed.

Is JAMM the right APAX LAB profile for your coffee?
While JAMM helps with sweetness and depth, other qualities of your coffee can be elevated with these APAX LAB profiles:
Want brightness and vibrancy? → TONIK
Want florality and elegance? → LYLAC
Want texture and harmony? → KONFLUX
JAMM is a useful starting point when a coffee feels thin, sharp or lacking sweetness, or when you simply want to push an already rich, fruit-forward coffee further. Start with what you taste, decide whether the cup needs more sweetness, depth or body, and adjust gradually.
