This is a concentrated essence to use wherever you want to easily add a specific flavour. Maybe a Summer Ale with Lemon flavour?
The best way to use these in beer brewing (or any other liquid) is to take multiple samples of a specific volume (i.e. 200ml) and dose them using a pipette in different concentrations - then compare and pick the one you like most - then scale up from there. A little can go a long way!
