“(T)hat bottle of red from the little village you found when you and your first love got lost in Tuscany on that rainy night, was the best bottle of wine the world has ever made. Just don’t try that bottle of wine again sitting alone while watching a Star Trek rerun.” — From, “Proof: The Science of Booze,” written by Adam Rogers

It’s proven over and over that context has a profound effect on the taste of what we drink. That sense of place, or people with whom you experience something, a special date, the angle of the sun … they all influence our flavor memories in inexplicable ways.

So getting a big sip of Four Roses’ 2015 Limited Edition Small Batch last July in the Lawrenceburg, Ky., distillery’s sensory evaluation lab—and poured by new master distiller Brent Elliott from a marked lab bottle, not a pretty bourbon vessel—helped pile up the experiential points on my palate to make that a significant memory.

And surely it made the whiskey taste better, though it didn’t need it. It was strikingly good that afternoon, and as I sipped it, I planned how to get my hands on a bottle of it when it became available two months later.

In late September I landed just one, a $129 purchase split between me and two Four Roses fans. We poured about a half ounce, sniffed, tasted and … stopped. Straight out of the bottle it was hot, simultaneously fruity and fiery—far hotter than I remembered tasting in the lab and far spicier than I expected at 108.5 proof.

High-proof liquor generally needs a rest in the glass anyway, so we walked away for a spell, let it air out and nibbled on some fatty country ham. After several minutes we returned to the glass to find aromas of spearmint, cedar, oak and vanilla, no looming pepper to warn a further rest was required. So we sipped again and got toasted marshmallow, caramel and cinnamon all over the exhale. More waiting and more small sips followed, and fruit showed up: apple and cherry in particular. The finish was fairly short and dry, and the descent delivered a warm burst down the pipe. I liked it, a lot in fact, but I wasn’t wowed by it as I was in the lab. So I corked the bottle and shelved it for later.

About a week later, when a 3-ounce press sample arrived, I took it to my office and let it sit on the desk, unopened, for several days. I knew some business colleagues would stop by over the following week, so I planned to share it with them and get their opinions.

When I cracked open the mini-bottle, out came the standard and formidable oak notes you expect from Four Roses. Sips brought on some more nuanced flavors like toffee and dark brown sugar. One whiskey wonk friend studied it carefully before mumbling, “Juicy Fruit,” referring to the popular Wrigley’s gum. He was right.

A day later I smelled the empty, dry glass on my desk and got notes of toasted marshmallow and graham cracker—yeah, I’d have given anything for a stack of warm s’mores at that moment. But I settled for another tiny pour, maybe a quarter ounce, and sipped it. Still flavorful, but still hot.

And then it dawned on me: “Proof it down, Bozo!”

I added a few generous drops of water to open it up—and then kicked myself for waiting so long. Immediately, aromas of toffee, cherry and pipe tobacco curled up and out of the glass, and a small sip dropped off deep cherry and oak notes at the midpalate. A little leather and tannin arrived to play on the exhale, making this once confounding (to my taste) bourbon a real delight.

Most stunning was the change in texture: a little water turned the mouthfeel into light honey syrup: silky and soothing as a toddy. My best guess was I’d knocked the proof down to just above 90, which softening it a good deal without removing all its bite.

I attach no pride to the fact that my palate favors high-proof whiskies over lower ones, but this one certainly turned that notion on its head. I was sorry once again that I’d waited so long to proof it down.

As the last official “FR-LR” created under the direction of now-retired master distiller Jim Rutledge, I’d say it’s worth finding if you can. Get at least a pour of it at a bar if you can’t find a bottle.

For what it’s worth, I’d strongly suggest two Four Roses private selection bottles chosen by Rutledge: the OBSO and the OESV, both of which were available only in the gift shop this fall. At $72 each, they’re not cheap, but they are phenomenal.

Interestingly, they’re both higher proof than the 2015 LR (112.6 proof and 112.4 proof respectively), but they drink softer than the 108 proof. However, both private selections are younger whiskies (11 years and 9 years respectively), versus the much older blends in this year’s Small Batch: a 16 year-old OBSK; an 11 year-old OBSV; a 15 year-old OESK; and a 14 year-old OESK.

So perhaps it’s old bourbon that ignites my taste buds? I’ll happily commit myself to further research.
