During the day, water - lots of it. Anything less than about 5 liters and dehydration is a risk.
6 PM is aperatif hour (which can last many hours, time is elastic in the south of France). The vat gets opened and the chorizo is produced. Things start to get funny from that point onwards.
If however anyone were to drop by with a case of chilled Staropramen or even a few Erdingers, they would receive a warm welcome and be swiftly relieved of their beer.

Staropramen, really? I worked in that brewery part time while in college.
See I can buy czech beer in USA, but only bottles, you can not get the atmosphere of Prague pub when you go grab a beer or two after the day's work.
If you could find it, Bernard is excellent:

There is only one thing in the world better than the atmosphere in a Prague pub, and that is the atmosphere in a real Irish pub, but I'd be happy to discuss the point over suitable refreshments.
I had a lovely week in Prague in '94, I think I sampled most beers on offer, I only know because I have the photos. Bavarian and Czech beers rule in my opinion. Zlatý Bažant from Slovakia is not too shabby either.
Imported beer here is generally silly price, except for (oddly enough) Belgian beers of which there is an ample choice ! Grimbergen and Jenlain sring to mind handily enough. God bless those saintly monks devoted to their craft.
But for ease of dispensing, and to avoid cluttering the garage with empty bottles and tops, the vat of wine in the corner keeps everything ship shape.
