As it turned out quite hard. To get a nice round and balanced bitterness to harmonize and meet gently with the other flavours took months to develop. Solubility, extraction rate, pH, water hardness, temperature was terms in use. Before launch the tonic was analysed by a lab to define the content and quantities of quinine, quinidine and other alkaloids.
The result, a locally produced and hand made tonic of premium quality.
A tonic that lifts a standard gin to the sky and make a great gin justice. In addition, an excellent non-alcoholic alternative.
