The difference of between locations of single malt scotch's (islay,highlands etc.)

I have been drinking scotch for about 6 years.I am a fan to the islay scotch's.Iv'e had laphroig,bunnahabhaim,laughvalin and many others from that region and enjoy the smokier character.I also like glenkinche however I always forget to look where it's from.My question is what is the difference between all the other scotch regions (highland,speyside. etc) and what are some good suggestions on the better of the scotch's.I apologize for the spelling.

Hey there Fancybrady! Glenkinchie is a Lowland malt. The distillery is located south and east of Edinburgh and is one of two constant working Lowland distilleries (the other being Auchentoshan). Bladnoch is the other Lowland Distillery, but it only produces a limited supply. Lowland malts are known to be light in body and flavor, herbal. Each region produces a spirit with its own characteristics which can be tied in to the geographical location, water and also the subtle differences in the way its produced. As for what are some of the better Scotches....that's up to you. I can tell you the ones I truly enjoy, but that in no way means you would like it as well. Just because many Scotches cost a lot, doesn't always mean the they're guaranteed to taste better - to you. You make our own best call on what you think is superior to the rest - you are your best judge of taste. I love Glengoyne 10 year old (about $40), but I'm also a big fan of Balvenie 21 yo Portwood which costs over $125. Do you ever go to Scotch tastings? I find this is the best way to explore all the different Scotches Scotland has to offer....you'll learn a lot, enjoy the food pairings and likely have a wonderful evening.
