Why is my scotch going bad?
Alright, new to the whole forum and signed up just for this specific problem i've experience. I got turned on to scotch about 2 years ago, johnny walker black to be exact. Liked it but I was a college kid so couldn't afford it on the regular basis, I moved down to Lauders. I know, dirt cheap, disgusting, has no place on this page. Nevertheless.... point being, I drink lauders a lot and then when i feel special or have a bit of cash i grab some Dewar's White Label. So... over the holidays I new i had some time off and i opted to grab a half gallon of Lauder's since I was doing a whole lot of nothing. I figured it'd get me through the week, I had no work so.... yea. Basically I cracked it, didn't hit it real hard, I kept it sealed, but I probably drank it for 5 days and then it sat for another 2 or 3, so roughly a week passes and there's a good 6 ounces left. I'm drinking this stuff and I can taste a "distinct" sediment. I was thicker tasting and I felt a heavy feeling of a "graininess" on my teeth with every sip. Understand I'm a fairly grizzled young man to be accustomed to drinking this stuff on the regular basis, but it was god awful. Further more, I purchased some Dewar's white label about two nights ago, so it was opened 48 hours prior to this post. When I opened it I drink about 4 to 5 oz out of it, not much at all. Sealed it up, didn't touch it last night, got into it tonight though. And I'm experiencing the same grainy sediment feeling I had from before. I don't think it's the air to scotch ratio or evaporation, i keep the cap on the bottle in between pouring it so it's not like my bottles are open for hours at a time. Now one thing that I think may be a factor is that It's kept in my basement, both bottles were. I live in michigan, it's winter, my basement probably gets down to 50 or maybe 40 degrees at night, just a guess. I don't know if that would damage the scotch or not. I've been drinking the stuff for 2 years and never have experienced this problem before this past month. So I'm wondering if anyone else has had this happen, i've found nothing online so far. Thank you in advance for any input you may contribute. Sorry if I'm just bothering the whole whisky.com community.
