Bourbon shot, tips on getting this look?

Saw this image on a review site and was trying to figure out how they did this one.

What throws me a bit is that on the cork is decently lit from the lower portion up yet 2-3 inches down the band on the neck is fairly dark. The contents of the bottle has that nice golden amber glow too. I attempt these shots though getting it in a one take is elusive.

Your insights on how this may have been done is appreciated.

the starting setup I would try first...

• Transmitted light thru the lower back of the bottle and bourbon, from immediately behind the bottle
  
• Main light to camera right side of bottle, elevation at about 2:00 o'clock and aimed downward toward bottle
  
• Fill via snooted illumination of cork from camera lert, elevation about 8 o'clock and aimed slightly upward
  

Thanks Wilt!

I've been attempting a one shot take without any similarities. Managed to get a close approximation with 4-5 shots.

The bottle glow for the first.
Table shadow second.
Background third.
Neck label forth.

Some variations to mix in. Fun and interesting to figure out these shoots. This will allow me some practice doing a composite.

I did this 3 decades ago, as my 1/2 day project during a product lighting workshop...three exposures on same piece of 4x5 transparency film
You may have seen it on POTN before. Most of the 1/2 day was set layout and figuring out the component pieces of the shot, like light source placement and control of light for each of the component elements shot on Polaroid to evaluate technique...and IIRC about 10-20 min to actually make the composite shot (rush before class resumed) with a few different pieces of film in the event of error.

Shot about 200 frames and gradually realized how to integrate some of the lighting to get the results. Wasn't able to get as defined a bottle shadow so that one I'll need to work on. This is a two frame composite since the grided reflector left a whole highlight down the neck. The label is one from a diffused shot.

What are you trying to do, which makes you not happy with the bottle definition? I see only the lack of a highlighted edge...white panel reflection (or narrow long softbox) placed at correct location does that.
I can see your Main is what seems to be a somewhat smallish source.

Thanks Wilt! Some of the ads on first look seem simple yet that may not be the case.

I'm trying to duplicate that bourbon shot as precisely as possible. Today I'll work on how they achieved such a crisp shadow to be like that.

The main has an 8" reflector with a 40 degree grid installed that is about 5' away from subject. A graduated reflector is on bottle left which can use a bit of refining as the placements reflects a bit to much back. The black flag turns the fade into a solid black so getting a bit more believable shadow graduation is desired there as well.

Pleased with this version. A few subtle changes in light placement brought some nicer results. I ran out of stands to hold flags which I didn't originally consider necessary. LOL. One more session to dial in a few areas.

My final on this bottle. Wanted a bit of graduation to the contents and this is about what was in mind.
