I don't think any evidence has been shown to prove that Heineken refreshes the parts that other beers can't reach, however I suspect that we each have our preferences for beers we feel are in with a fair chance of reaching the bits that matter, when we can get them and when the pub has the time to look after them properly. I remember some years ago recommending a poster try Fullers ESB if he ever had the chance in preference to his choice of the disappointment his recommendation of Timothy Tailor's. I'd been up his way a week or so before and not only suffered his recommendation but when a fellow patron of the pub stood beside me in the toilet and commented "They flog it to you and get it all back when you leave", I realised the wisdom in his words. Sadly our much loved friend chose to take my advice on the best beer I've found in the havoc of the bar in a busy railway station, most likely sampling the dregs of the barrel. Were it possible we could organise a pub crawl of each other's favourite haunts. Maybe we might prove to each other we were both right. Your homework for today is to define why you prefer one beer over the rest, say whether you'd be prepared to travel to drink it and how you'll make your way home again after i.e. by driving, getting a lift or have the fortuosity of owning a dog that will drag you back home..
