To better show the contents of the bottle, sometimes the back label needs to be removed if there is one and a reflective foil type paper cutout set up at an angle behind the bottle to reflect light through the liquid.
Based on Miranda1's recommendation, I picked up a bottle of Lagavulin 16 Yr Scotch Whisky. I'm looking forward to trying it later today. (I reflected light through this bottle)

My favourite of the Isay malts by far. It's pretty hard to fine locally, I use to travel quite a bit to Webster NY prior to the pandemic and always made sure I stopped at the US tax-free shop to pick up a bottle before crossing over to Canada.
Not sure if you've tried Islay scotches before, it's a unique taste quite different from mainland scotch.
