The approach exploits efficient sympathetic cooling of \$^133\$Cs via \$^87\$Rb in a magnetic quadrupole trap prior to further evaporative cooling in a levitated optical trap. Sacrificing all the \$^87\$Rb during the cooling, we create single species \$^133\$Cs condensates of up to \$6\times10^4\$ atoms. Tailoring the evaporation to retain some \$^87\$Rb, we simultaneously create condensates of \$^87\$Rb and \$^133\$Cs in the same trapping potential, each containing up to \$2\times10^4\$ atoms. We observe a striking phase separation of the two species revealing the mixture to be immiscible due to strong repulsive interspecies interactions.
