I've tried various experiments and have found that a beer around 3pm often leads to the best productivity gains for technical work. More than a beer and the productivity starts to tail off, but it's much the same for me as with coffee. I don't drink so much beer these days, but an Aperol or Campari and Soda around 4pm seems to be quite a nice and not very alcoholic way to round off the work day now and again. In the UK, sales lunches tend to be fairly boozy affairs - this is an exception to the 1 pint rule, although I generally wouldn't go past a third pint of beer on a sales lunch unless we'd agreed we'd take the afternoon off for some time out.
