Cant figure out why the rendered image has a large black and white artifact (on the bottle on the right)?
This is the blender file.
Appreciate any tips!

That big error on the top is caused mostly by fireflies and the denoiser.
The denoiser has a hard time with small bright elements surrounded by darker pixels.
Just for comparison here's the image with no denoising:
See:
How to properly denoise renderings?
What is the solution?
You need more samples and less aggressive settings for the denoiser
Or get you can get rid of the denoiser completely and use some clamp indirect to control the fireflies.
But you can also avoid those hot spots and fireflies if you change the lighting on the scene.
Don't use point lights to light shiny and transparent objects...
They will be reflected as bright shiny points and are more likely to cause fireflies.
If you use large area lights fireflies are less of a problem. Here's the same scene at 600 samples, no denoising and no clamp indirect.
read:
https://blender.stackexchange.com/a/50576/1853
Other advise. Try to avoid high levels of subdivision (like you have in the plane used in the background). you are generating a very large number of unnecessary vertices by setting the subdivision to 6. Very rarely you would need more than 3.
Read: Blender render crash when using subsurf modifiers.
Last piece of advise: Try to make your objects to the size they would be in the real world. Your bottles are larger than a house at 9m tall. It makes a difference in terms of the size and intensity of the lights (and if you are going to do any kind of physics or fluid simulation), and also in terms of the depth of field on the camera.
