Abstract
Some embodiments of the invention relate to an article of manufacturing for printing on a foamed beverage comprising: an ink-jet cartridge; and a sugar-poor and unfermented-wort-based ink formulation disposed within the ink jet cartridge. The unfermented wort is the primary colorant of the ink formulation. In embodiments of the invention, (i) a ratio between the EBC number of the ink formulation and the 25° C. viscosity thereof is at least 400 (centipoise)−1; (ii) the ink formulation is characterized by at least a EBC number of at least 1800 colorant units; (iii) the ink formulation comprises at least 10% wt/wt carbohydrates; (iv) the ink formulation is sugar-poor such that a ratio between a wt/wt % concentration of soluble sugars and a wt/wt concentration of carbohydrates in the ink formulation is at most 0.2 (e.g. ≤0.1 or ≤0.05); and (v) at least 60% of particles of the ink formulation are sub-400 nanometer particles.
