Have already tried several flavors. Peach and passion fruit is my favorite. As the drink has no carbohydrates, you can drink it all day. Best simply take an empty plastic soda bottle 1L. Half fill with cold water. 4-5 splashes pure. Then let back inside running water. Finish and down in the refrigerator. Then the next day to drink the same, so that the water does not protrude so. Open daily two bottles of the business or to the gym. Since taking the water from the tap (quality is usually better than the D way, in the bubble bottles) you pay only for the quasi Mineral sauce. A bottle of the drink stands with me about 3 weeks and I drink every day about 2 liters of mineral.
