Extra Stout (Sam Smith's)

While I was out at Richmond I also got into a bit of Sam Smith's Extra Stout (4.5% abv). SS Extra Stout is served from nitro-keg and is very similar to Guinness. I would go as far to say that it is an excellent clone, although it does have marginally more flavour and has a nice coffee tang that modern Guinness tends to lack (although it did ten years ago?). The beer was ok, but in general I despise nitro-kegs. There is something slightly dissatisfying about having a beer with a head the consistancy of shaving cream! Also generally as a rule: Nitro-kegs tend to be cellered alongside the lager collection and as such come from the tap at about 2 degrees! Who wants icy cold stout? Not me...
