Honest question, what's the difference between whiskey and scotch? I know scotch is Scottish, but what else is different about it?
only scottish whisky is whisky (no e), everything else is whiskey
as for the difference, every whisky is different, even between scottish whisky's they vary massively.
The most dominant thing is probably the local geography. Whisky is aged for countless years in barrels and where its aged as well as what environment the malt is handled in play a huge role.
western islands, islands that are built on peat stores produce strong earthy and peaty malts, often with very salty briney notes.
highland malts, mostly light and floral
eastern scotland, speyside, more medicinal or metallic tones
lowlands, more grassy flavours
irish malts taste of leprachauns...
then you get the barrelling. some producers will use new wooded barrels, other ex bourbon barrels, sherry casks, maderia barrels, these will all add character, flavour and depth to the finish whisky.
So not even all scotch are the same, thats before you even start comparing to irish, american, japanese (which fwiw are some of the best in the world)
but before all that you have the type grain used..
A "malt" whisky is made from fermented barley.
then you have "grain" whisky which is made from something other than barley, usually corn, wheat or rye.
Grain whisky is cheap and shit and can be quite sweet.
Malt is not.
(then you have Bourbon which is corn - the minimum requirement is 51% corn, so the cheap ones are 51% corn with a load of rye or wheat whiskey in)
From that you get either:
Single Malt - a whisky made only from one specific batch of malted barley
Pure Malt - a whisky made from only malted barley but from several batches
Blended whisky - which is made from a mix of malt and grain whisky. How it tastes varies on how much malt v grain so something like Teachers, has a high malt content low grain so is quite harsh, something like Famous Grouse has a much higher grain content so is quite light and sweet..
