Liquid through glass material is not visible?

Hey all, when I render out my coffee it turns out like this but I want the coffee to be more visible and darker when seen through the glass. Does anyone have any tips?

Have you tried increasing the number of Transmission bounces?

I upped it up to 34 and it was still the same

Can you post the file, or at least a pic of the shader node setup?

Coffee and glass nodes

How is the glass/coffee surface modelled? Is there a separate glass/coffee surface right next to each other?

If there is and the scene is static, model the glass/coffee intersection as 1 surface, and put in an IoR of ~1.25
