Coffee Appreciation

Am I the only one who's never got on with Square Mile? I love it in the cafes that serve it but I find it really hard work at home, especially on espresso...I've tried several different blends and single origins and they're always a nightmare to get right.

I've not found single origin beans to work for espresso (though this may be down to my finnickity europicolla). But the espresso blends all seem ok to my uncultured tongue.
