Coffee and Tea are just drinks to some people, other people take them more seriously, some people make a living out of it, as far as I'm concerned, yeah, they're a drink but if you're going to make them, you may as well do it right. Some things should be done and some should be avoided to this end, they include:

• Never keep coffee in the fridge-if you have to, store it brefily in the freezer, the oils get damaged otherwise
• Never use boiling water-coffee isn't tea, if you pour boiling water on it, the coffee will scorch
• Make sure you buy coffee made with Arabica beans, as they're smoother and sweeter but you will need some Robusta beans if you want a nice créma
• Never heat milk beyond 75° as it will burn
• If, when you're steaming milk, the steam starts to make a metalic, loud noise, there isn't enough air in the milk, lower the wand and introduce more bubbles, the milk will then make a more muffled steaming sound
• To make foam, the best milk you can use is skimmed milk. Due to pasturisation processes, the higher the fat content, the less foam is made and sustained
