If your Specular material has Fake Shadows enabled, caustics will not be calculated. Also if your Kernel is a Direct Lighting kernel, it will not calculate caustics. Use Path Tracing or PMC (preferably with a low Caustic Blurring parameter <0.05) and Fake Shadows disabled on your glass. If there are many layers to your object, make sure to increase Specular depth in your kernel settings to allow light to bounce through the glass.

Whats your scene size? For correct caustics they should be pretty 1:1

what happens when yuo adjust the rayepsilon? might get more detail out of that

How is your lighting setup? Probably you need more (directed) light from the back to enter the glass. The lights now are a bit dull/even

by the way, with that lighting setup the caustics actually look pretty decent. Try finding reference images of photos that should represent the actual caustics
