Poured myself a nice portion of Knob Creek and settled back to enjoy it and a book. After about half an hour I noticed that some of the bite was gone from it, but that was ok I was enjoying all the other flavors. After about an hour, maybe an hour and a half I noticed that the last sip was very cloudy and was, for lack of a better description, flat. Like soda that had been left out too long.

I had searched the boards to see if anyone else had this happen, but couldn't find anything.

Any thoughts?

Any help would be greatly appreciated.

I'd guess that the decreased "bite" is a result of your palate adjusting to the relatively high proof. As for the cloudiness, I don't know. Backwash?

If I have a very small amount of bourbon in a glass and leave it overnight, by morning it's cloudy. I don't think it's all backwash since it was not cloudy until it sits for several hours. Oxidation is my take

I thought about that too, but cloudy after an hour or so?

You got me on a 100 proof bourbon going cloudy but like they say cloudy isn't going to hurt you. Usually cloudy bourbon is unchill filtered bourbon that has gotten cold that is under 100 proof. It's all aesthetics like I said it won't hurt you it's just the fats in the bourbon collecting together. But KC is 100 proof and chill filtered so I have no clue. The flat could just be your tongue going numb. That would depend on on how much you had to drink and how accustomed to drinking you are.

Thanks guys for the input! Still have no idea what happened. It was cool in my apartment, but not frigid. I don't think my tongue was numb, it was a small pour and I was pretty much sipping it over the course of an hour or so. By the time I got to the end there was no bite at all and it was pretty flavorless. I couldn't even finish it. I wonder if it was the glass?

I was going to suggest that their may have been soap residue in the glass. Not sure how you washed them, but typically, even if I put my whiskey glasses in the dishwasher, I almost always rinse them under water and let them dry again to make sure there is nothing left in the glass. I'd rather be careful than ruin a good pour. I'm just as anal with my wine glasses.

I'm thinking you may be right. I had another pour of the Knob Creek last night, in a different glass, and had no problems at all. I'll have to be more careful with rinsing in the future.

That could be it

Oxidation probably. Good whiskey will do it. I consider it a good way to tell a whiskeys quality. I freqently take barrel samples and put them in a solo cup maybe an 1/8 inch deep. Leave it out in my office, it has a ceiling fan. Ususally will turn cloudy in an hour or so. If is does not, I get worried.

You know what, now that you mention it I had set the glass down in front of a fan. It wasn't blowing into the glass, but over it. With the cooler weather I didn't have the fan on last night.

As an aside, cool experiment with bourbon. I'll have to remember that.

I've noticed this. As a biochemist, my immediate guess was that that the alcohol had mostly evaporated but water had not. Ethanol has a much higher vapor pressure than water and will evaporated much more quickly from a mixed solution. Then the components of the whiskey that were soluble in alcohol now precipitated out of solution (turning cloudy) because the composition solution changed from mostly alcohol to mostly water, in which they were not soluble.

I can do the experiment in lab to determine if this is purely oxidation or evaporation, or both.

Bourbon experimentation, not that is science I can get behind.

I find that the best way to really get a sense for how good bourbon is, is to leave it in a cup with a few drops left overnight. Most of the time if it smells a little funky, it is better stuff. Usually lower off the still stuff. Makers Mark before it was dumbed down really would xhange overnight. The new stuff, not so much.

Now that's interesting. I wonder what would happen with Maker's Mark White?

My bourbon never goes cloudy until I've had four or five pours. Oh, wait...:lol:
