For sheer refreshment, nothing beats Austria's Almdudler soda; it's like a thirst-quenching mix of zippy lemon seltzer and ginger ale, with a pleasing herbaceous undertone from the Alpine herbs that go into it. The name comes from the old Viennese phrase auf der alm dudeln, meaning "yodeling in the meadows." One bubbly sip and we're ready to do just that.
