Elsksa, could you please point me at any info on these settings for better caustics? I'm rendering bottles and desperate to get some good caustics but I've tried the PMC kernel and it doesn't seem to make any difference?

Thanks Elsksa, here's the IPR Render, the attachment of the basic scene and what I'd like to eventually produce on the Ballantines whisky photo. I know the liquid is wrong on the upright one but it doesn't really effect the overall situation. The issue is that the caustics are way too basic and blurry. It isn't just the scene, every time I do caustics and glass with bottles I have the same problem. Any ideas would be greatly appreciated

There's only one small very bright light in the scene so I don't know what else I can do, as you can see it's also not able to calculate properly with lots of blotches everywhere?

Thanks Elsksa, the scene is the correct scale, I've attached the zip file of the scene.
