This product is the world's first produced commercial butterfly pea flower extract - designed for the creatives in the cocktail and food industry and food and cocktail lovers. Contains the equivalent of 3-4 boxes of tea. Achieve a great color with just a few drops (will not water down the cocktail as a tea extraction might). If other ingredients are added that have a higher acidity (like limes or lemons), the color then changes from blue to purples and pinks depending on surrounding light & the acidity (pH) of the drink or food it is mixed with. More Acid = More Purple - The color is blue at pH 8 to pH 4 (if in neutral substances like water, clear spirits or milk). It will change to royal purple at pH 3 and to bright pink at pH 2 (so the more acidic it becomes after adding other ingredients).
