I used to keep mine in a very cold refrigerator. Not freezing, but close.
I was sadly forced to give up my Scotch habit a few years ago.
Who knew Scotch and epileptic seizures don’t like each other!
So have an extra for me!
Is it the alcohol that causes the seizures? If not, try Tequila. The finer varieties of tequila blow scotch away, quite frankly.
