Coffee. Long black first thing, cafe latte until noon then long machiatos till midnight. If I'm drinking coffee after midnight it'll be double shot short blacks.
I like beer, many kinds of beer, in warm weather a lager or a wheat beer, in cooler weather a ale, porter or stout.
I'm also partial to a sparkling shiraz, cabernet sauvignon, or pinot noir. I'm not too fond of whites but do quite like a Semillon.
