From a sometimes bearded real ale drinker.........
Efes is absolutely fine, much better than the "brewed in Northampton by Danes stuff, I do though occasionally have a bottle of Efes Dark by way of a change. Along the lines of Theakstons Old Peculier rather than a bitter. Usually Tl 5 for a 33 cl bottle but at 6.1% is definitely not a session beer.
