I've had the Coffey but don't remember it. I did like the grain but like with Yamazaki, the explosion in popularity of Japanese whiskeys in the US market has caused it to go up considerably in price. I first tried it around 2015 and it was in the mid $50 price range. Within a year or two it was $20 more. I haven't looked lately but wouldn't be surprised if it is over $100.
I really have to start buying cases of stuff I like if for no other reason than investment. I can think of at least 4 different names that were inexpensive a decade ago and now are double or triple the price and hard to find.
Yamazaki 12, Col Taylor, Eagle Rare, Nikka malt, Laphroaig 18. All were available and relatively inexpensive just a decade ago
