Clearly - we do not want caustic acidity and little unpleasant bitterness in coffee.  

These are the prerequisites for this:

The wise selection and composition of green coffee varieties.
Each variety has its own flavor profile and contributes these characteristics to the blend in the optimal ratio. And even when selecting the varieties, you can make sure that they are low-acid coffee beans. You can compare it to a wine cuvee. The roast master knows how to create a distinctive variety from this. Balanced, yet distinctive. That's why most Coffee lovers drink blends rather than single-origin beans, which often lack complexity of aroma and flavor.

The blend ratio between Arabica and Robusta beans

It is now common knowledge that a high Arabica content is not synonymous with high quality. There are just as many bad Arabicas as there are high-quality robusta beans. It is the interaction of these two that is the deeper secret of a good espresso coffee. Perhaps it can be compared to bread: you don't necessarily notice that there's salt in it, but you do notice when it's missing.

The roasting process

The duration of the roasting process plays a very decisive role. Especially in southern Italy, they roast for a long time (20-28 minutes), but at a low temperature. And it is precisely this that ensures that chloragenic acids are minimized and bitter substances are released from the beans. In Naples, it goes so far that some beans leave the roasting drum shiny deep black to almost oily, because the long roasting causes the contained coffee oil to escape. This is not a quality defect, but actually desirable.

Attention! Stomach friendly NOT ALLOWED! 

Did you know that in Germany it is not allowed to call coffee gentle on the stomach? This also applies to stomach-friendly coffee or compatible espresso or digestible coffee. This is unfair competition. 

Justification: 

"Wholesome coffee" is a non-specific health claim. And according to the Food Health Claims Regulation, this may only be done if it is based on an alleged character of an approved health claim.
