I mostly enjoy IPAs because I like a beer you can taste. I enjoy a strong flavour with a bitter kick to let you know you're tasting it. It's kind of how I like my food spicy; for some it takes away from the flavour, for me it carries it.
I enjoy a classic English ale, anything from Old Speckled Hen to Hobgoblin. Great with a meal in a beer garden.
Best beer for me is Belgian. Sour cherry varieties that pack flavour (and alcohol) and require sipping rather than drinking. Which leads me onto....
Scotch! I'm a relative newcomer to this one so I can't really describe what I like from these. I have a nice Mac Spey currently which I drink with a drop of water.
Finally red wine. Red wine is real wine to me and I like it dry with oaky notes and hints of berries. Other wines taste like juice to me.
