We use the method of optimal distillation profiles to compute the low-lying charmonium spectrum in an Nf = 3+1 ensemble at the SU(3) light flavor symmetric point (mπ ≈ 420 MeV), physical charm quark mass and lattice spacing a≈ 0.0429 fm. The spectrum and mass splittings display good agreement with their values in nature and the statistical errors are comparable, if not smaller, than those of state-of-the-art lattice calculations. We also present first results on the mixing of charmonium with glueballs and light hadrons obtained in a similar Nf = 3+1 ensemble but at larger pion mass.
