How to Drink Beer

I know what you're thinking, 'I already know how to drink beer.' If you're a beginner to craft beer, you might just be wrong. There are a few simple steps you can take to make your enjoyment of beer, and even good quality wine or spirits, so much better!
Step One:
Glassware
ALWAYS pour your beer into a glass. Even if it's not the correct style of glass for the style of beer, never drink it from the bottle or can. I prefer a tulip style glass, more specifically a Duvel glass, which is perfect for almost any style, because it's wide at the bottom but narrows towards the rim, to force aromas into your nose, where their supposed to go. No need to be pedantic about glassware though, just pour it into something.
Step Two:
Appearance
Put simply, does the beer look good to you. What colour is it? What kind of head does it produce? Can you see the carbonation streaming from the bottom of the glass. Is it clear or cloudy We drink with our eyes first.
Step Three:
Aroma
Stick your nose right into the glass. As I mentioned before, the correct glassware will help with this, but it's not essential, good beer will still smell good in the wrong glass. Start thinking about what aromas you can pick out, is it more malty or hoppy, is there an alcohol presence in the nose? This should give you a rough idea of what it should taste like.
Step Four:
Taste
Finally you get to taste the beer. No need for huge gulps like you would with a Heineken. Take your time, craft beer is to be savoured. Take a sip and let it coat the inside of your mouth. How does the taste match up to the aroma? What's the mouthfeel like? The mouthfeel of a beer can range from light bodied, such as a pilsner or hefeweizen, all the way to full bodied, such as an imperial stout or barleywine.

Follow these simple steps and you will soon find that you'll no longer simply like or not like the beer, but be able to explain your opinion either way, and perhaps appreciate styles you didn't before.
Cheers!
