One more last beer gift suggestion, at least until I remember something else.
You can download Beer Lover’s Britain for £5.99. Jeff Evans includes all the vital information you’d expect but also address the questions you really want answers to.
Should there be a head on my pint? Is it in the right glass? Is it meant to taste like that? How much does a pint cost? How do I pay the bill? Can I join in the games? Am I allowed to drive after drinking? What can we eat? Can we bring the children in? Is smoking allowed? Can I expect table service? What time does the pub close? Can we stay at a pub? How do we get there?
As long as I’m suggesting guide books (avoided in making the list above because of their specialized nature) I should mention Good Beer Guide Prague & the Czech Republic. There’s a chance we’ll make it back to the south of Germany and the Czech Republic sooner than later, so already committing this book and Trips! (South) to memory.
