Laphroaig 10 Year Cask Strength is an Islay single malt Scotch whisky produced at Laphroaig Distillery in Port Ellen, Scotland, and owned by Suntory Global Spirits. Matured for 10 years in ex-bourbon casks, it is bottled at natural cask strength without chill filtration, with ABV varying by batch, typically ranging from around 55% to 60%. It generally retails for around $60 to $100 per 750 mL bottle in the U.S. market.
While you can catch the whiffs of citrus and grapefruit uncut, these are far stronger when you add a splash of water. Try adding more and more as you drain the glass (which will have the side effect of making the glass appear to never empty) and out come more tropical notes of banana, lychee, and pineapple, even a touch of coconut.
