Famous Grouse is a cheap scotch. Scotch is one liquor that ages extremely well but tastes horrible until its aged for about 12 years at least. The regular famous grouse is probably 3-5 year average aging (it’s 6th highest volume scotch seller globally, Johnny walker is by far the highest volume scotch seller these days), if that. Unfortunately, that means for a bottle of scotch to taste decent its going to cost at least $40 with the better ones costing $75 to $300. If you want a good bottle (or glass) of scotch, try Macallan 12 (Glenlivit is another good brand that is cheaper than Macallan, not as good, but solid).
