Whisky drinkers

A never ending question that lol. There are some great whiskies out there worth a try for not a lot more than what you tried. Thing is you probably need to figure out your taste buds as to what type of whisky you are likely to prefer. I couldn't speak about blended malts as I only ever drink single malt. Some regions produce whisky that are heavily peated and smokey in flavour and undertones, others with more fruity and sweeter undertones. You tend to prefer one or the other.

I would buy 2 - a Glemorangie 10year old and a Laphroaig 10. I think they are both excellent malts for their money - both available for under £30. They sit at separate ends of the taste spectrum - one sweet and the other smoky. It will answer the question as to what your taste buds will like and from there you can exclude a large proportion in the future

Depends on YOUR taste.... I hate smokey/peat drinks myself, so my faves are Glenmorangie and Penderyn medera - very similar sweet edge to both.
Rather than drop a load on stuff you won't enjoy, find a whiskey shop that will guide you through a few samples , then buy a bottle you'll enjoy - yes you would save money at the supermarket ,but it's money well spent as you'll discover your preferences.... then you'll know what to target in the future.
Don't limit yourself to Scottish though... Ireland, Wales and Japan make some cracking stuff, as do other places no doubt.

Is it also worth getting a decanter?

My drink of choice at the minute is Ardbeg 10, not for the fainthearted though. Shall we just say its very medicinal but very nice.

Never heard of wisky before must be a new drink;)

Some people swear adding a little water to whisky can enhance or bring out some flavours. My personal experience - it's the worst thing you can do to a decent whisky. Try it neat every time at least at first with one new to you. No harm in trying a little water, but it is usually very little. I have NEVER added water to whisky (nor ice for that matter) and never will. For me it's a sin

@newbie68 makes a really good point about whisky. Some do really benefit from literally 2 or 3 drips (and I mean drips) of water. I was skeptical about this until being given some comparison glasses on a distillery visit. I even bought the pipette to do it at home. It really divides the room, but I find it works if you buy a cask strength whisky which are around 57% proof. One to experiment with.
