"how long will malt whisky keep in an open bottle?"

the air that gets intae a bottle does degrade the whisky...

maistly it is the alcohol evaporatin' that changes the flavours..

but it is maire complicated than that....

an' ai dinnae ken enough aboot chemistry tae explain it...

basically, yince a bottle is half empty ya have aboot 6 months tae drink it befair the flavours change (rather dramatically tae!)

keep this in mind when orderin malt a' a pub that disnae sell a lot o' malt...

maist o' they bottles arr wa' past 6 months auld!
wi' a muckle huge bottle like that- ya cannae possibly drink it all whilst it still tastes guid....

an wi' JW black... e'en a' it's best- it's no very guid!
