March 21st, 2026: Flock, Flock, Flocking In My Bottle of Bourbon?
So, you grab a bottle of your favorite Cathedral Ledge Distillery bourbon and leave it in your car on a chilly day. Or maybe you picked up a tasty expression from one of those sub-zero farmers’ markets we’re vending at. Then you notice the bourbon is cloudy—really cloudy, like Cathedral Ledge during a winter storm.
Has it gone bad?
No.
Is this normal?
Yes.
Will it go back to that fine amber spirit you know and love?
Absolutely.
Flocking is a mini science experiment in a bottle, and it's perfectly natural. While some brands choose to chill-filter their product to avoid this hazy, New England IPA-like appearance when exposed to extreme cold, we do not.
Why?
Chill filtering removes fatty acids and esters that are essential to mouthfeel. By choosing not to chill-filter, you get a creamier mouthfeel that coats the tongue and delivers a fuller, more flavorful experience—the way it was intended to be. We want you to experience the organic grains that go into every bottle, and without chill filtering, it’s like shining a spotlight on layers of flavor that keep beckoning you back for another sip.
The same effect occurs when adding ice or cold water to a non-chill-filtered spirit. Whenever a spirit between roughly 80 and 92 proof is exposed to 30°F or lower, you’ll get that cloudiness. You’re less likely to see the same effect in our bottled-in-bond or barrel-strength offerings (higher proof helps keep those compounds in solution).
But be forewarned: storing a bottle of non-chill-filtered bourbon in a freezer for long periods could result in irreversible, lava-lamp-like spirits. Though not harmful in any way, it’s a bit funky. So, as your designated spirit enthusiast, I recommend keeping these handcrafted bottles at room temperature and away from direct sunlight.
Look forward to a future blog where I’ll dive into why you shouldn’t leave any bottles of spirits in a hot car. Soon, my New England friends, summer will arrive, and this hot-car scenario will be upon us all.
