My daughter Rima and my son Karim launched an energy drink in 1990 called  Gusto, a superb organic herbal energy drink that is the most natural and effective way to get a concentrated and prolonged boost of energy and concentration.  With nothing but pure guarana, ginseng, Siberian ginseng and a Chinese herb mix called Mind Peak it delivers a natural uplifting jitter-free energy boost that doesn’t depend on synthetic caffeine for stimulation or taurine to calm the resulting  shakes.    The business was sold to a Dutch multinational in 2002 and now it is back in family hands and has recently launched ‘Gusto Cola’ a low calorie organic Fairtrade alternative to Coca Cola.
