We show that the properties of spinor Bose-Einstein condensates allow us to buildan analog Taub (axisymmetric Bianchi IX) Universe. We shall develop this proposal on the exampleof a rubidium condensate, where the relevant experiments are well within present daycapabilities. A better Taub analog however would be built out of a collective Rydberg excitation.
