I’ve normally got somewhere between 40 and 50 bottles of single malt on the go.
I think the best bang per buck is Naked Grouse, or as it’s now called Naked Malt.
It’s around the £22 mark , a blend of sherried malts , lovely jubbly.
Macallan pricing is bonkers, I think I’ve 3 bottles at the mo, all gifts but absolutely no better than any other Spreyside IMO. Owned by the Edrington group who also own Famous Grouse and Highland Park. They can sell everything they bottle so can drive the price.
