Altbier (Düsseldorf's Traditional Dark Ale) vs Traditional Shandy

Both drinks are built on beer, but they use it in opposite ways. The Altbier is poured on its own and served slightly cool, at 8-10°C, so its malty depth, mild hop bitterness and subtle caramel and roasted notes come through beneath a dense, off-white head. The shandy instead uses a lighter, crisp lager or pale ale as a base, topped with chilled fizzy lemonade for sweetness and lively effervescence. One rewards slow sipping of a rich, rounded beer; the other is a bright, adjustable refresher.
