Banks's "Amber" is just their standard issue bitter as manufactured for decades if not centuries. I like it if all I want is as said an inoffensive session beer. I do like their Mild too, if I can find it. There's a bit more depth of flavour. At 89p in glass bottles it's hard to complain.
I need to get some beer in for Xmas, my parents drink very little and certainly not beer. Last time my Dad commented to my Mum "we don't need to buy any beer for Xmas for Steve, there's plenty in". Turns out that "plenty in" was 3 bottles left over from the year before and well past its best. Fortunately the shops were still open and I was able to get some. Even then, if I drink more than 2 or 3 pints in one evening my mother has me down as "a binge drinker" and worrying about my health. So I'll get a bit in and leave it in the car and fetch it in 2 bottles at a time.
