Also Sainsburies is one of the better cheap whiskies going. Nicer than quite a few of the more mid-ranged offerings.
Thing is that I don't really mind drinking cheap whiskey within reason. I could never afford to drink Laphroaig or Bruichladdich or Jura or whatever any time I fancy a scotch. Drinking lower quality scotch does not actually physically harm me (apart from the same way all scotch harms you), and it is still more enjoyable than just sitting in a chair not drinking scotch at all. It's not the ultimate possible scotch drinking experience, but it's fine. What is constantly being implied and occasionally outright stated with regards to coffee is that this is not a good attitude: that you should either drink the best possibe coffee brewed in the most correct way or you should not drink coffee. This is a patently ridiculous position. I would never in fact argue that a good filter coffee doesn't taste better than an instant, in fact I can tell the difference between filter, instant, french press and americano pretty much instanty. However, to me, instant coffee, at least the brands I buy, tastes perfectly fine. In fact most coffee that doesn't come out of a vending machine on a train station is perfectly amenable to my palette. I am generally just quite laid back on most gustatory matters: I appreciate good things, but I don't constanty demand them, nor do I expect them. It's nice to have a fancy coffee or meal or scotch or whatever as a treat, but I can live perfectly fine with the standard fare.
The only place where this attitude slightly breaks down is beer and cigarettes, though this is in large part because I like very particular sorts of beer and cigarettes (ruby and dark ales and strong rolling tobacco in liquorice papers respectively) and these types are generally all of a certain quality. I do find drinking most common lagers or smoking cheap cigarettes somewhat unpleasant though.
