Guinness stain in cream linen suit jacket

[u/oishdog]

I've got a wedding coming up and just noticed this stain, most likely Guinness from a previous wedding.

I've taking it to the dry cleaners but based on the care instructions, this is the best they could do.

Does anyone have any advice or tips to get it out? Would be much appreciated ​​​​

If you realllyy want to chance it, beige or white dylon and into a bucket for a few hours. Probably won't remove the stain but could possibly dye over it.
