N2 - From Gross-Pitaevskii (GP) theory for ultracold gases it is predicted that phase-segregated three-component Bose-Einstein condensates (BEC) feature a wetting phase diagram that depends only on atomic masses and scattering lengths. This is unique in theories of surface and interfacial phase transitions and provides a new opportunity for experimental observation of wetting phenomena in BEC mixtures. Previous GP theory for two-component BEC relied on an {\it ad hoc} optical wall boundary condition, on which the character and location of the wetting phase transitions depend sensitively. This boundary condition dependence is eliminated by adding a third component and treating the three phases on equal footing. An unequivocal wetting phase diagram is captured, with phase boundaries calculated analytically using an extension of the established double-parabola approximation.
