Champagne is a complete dominant dilution gene, SLC36A1 on Chromosome 14. There is no known physical difference between homozygous and heterozygous genotypes. Champagne dilutes red to a gold color and black to brown or taupe. Champagne also causes the coat to have a distinguishing sheen to it, as well as diluting the skin to a pigmented pink (often freckled, giving it a purplish look from afar) and the eyes to hazel. Champagne on a bay base is called amber, on a black base is called classic, and on a red base is called gold.

Adding a single cream allele to champagne dilutes the coat even further, making the horse appear like a pseudo double-cream dilute. The names for these are the same as the basic champagne names, just with ivory or cream added in (ex. classic ivory champagne or gold cream champagne). Two cream alleles results in a horse that is almost an iridescent white color.
