1. The glass. Always start with a clean glass. Wash it in warm soapy water, then make sure you rinse thoroughly to remove any traces of detergent. A room temperature glass is best. Too hot and the beer can go flat; too cold and ice crystals form and make the beer foam up. Either way you risk making the beer taste bland. After all the hard work your brewers have gone to to create layers of subtle flavours you want to make sure you can enjoy every aspect.
2. The initial pour. Hold your glass at about a 45 degree angle. Then pour the beer down the side of the glass aiming at the point halfway between the bottom of the glass the the rim.
3. The tilt. When the glass is about half full tilt the glass upright. Keep pouring into the middle of the glass. This part is very important to create a good head on the beer. Depending on the style of beer you are aiming for a head of 2-4 cm. Find out more about why head (or foam as the Americans say) is good.
4. The drink.
Time to enjoy!
