32 yr old Springbank With White Sediment

[505Gibbs]

I have a bottle that is from the distillery and its in clear glass and NCF. It has thrown white sediment and has never been opened.
Is this a by-product of sun exposure or ???

505Gibbs - Springbank is never chill filtered nor is color added to the whisky. Since it's non chill filtered, the whisky contains quite a lot of elements known as " fatty acid esters " and " flavouring oils". These substances can come together to form either a haze or fine sediment in the whisky. Another thing that can promote sediment or haze is for the whisky to be kept in a cool environment. Shake your bottle and then leave it a warm environment which may help the haze to clear. You can rest assured there is nothing wrong with the Springbank whisky in your bottle.

Thanks Jojo!
I figured if you didn't answer - perhaps nobody would/could.
This bottle is kept at room temp and NOT chilled. I've been a single malt enthusiast for many years i.e. over 35, and I've never had a bottle do this hence the question.

You're very welcome! And...wow - a single malt enthusiast for over 35 years?! That's fantastic - it's no wonder you're one of our "Whisky.com Experts!"

The white deposit is called "floc" from the flocculation that happens as JoJo explained. The other cause is that the alcohol strength has dropped below that which will keep the FAE's in solution. There are only 2 causes of floc, temperature drop or strength drop. If it's due to a drop in strength then it won't go away.

Just found a bottle of the same - very rare whisky. My bottle has the same white sediment - not much, and got stirred up on the way home from the store. Bottle is sealed, so no worries about strength dropping. Since the whisky is not chill filtered, I am not worried. Hope this make you feel better
