You may have seen at various cafes around the world that there is a range of roast levels to consider when purchasing your regular cup of joe. For most people this choice will likely seem like a non-issue, however, for those who know what they want, having this flexibility will be a godsend.
People will generally drift towards darker coffee beans with a deeper roast in search of bitterness and body to their cup of coffee. This is a choice typically made to ensure that the drink is a rich and bold beverage.
For the most part, a typical coffee unless stated otherwise will be a light-medium roast to create that pop of flavour and complexity without burning off too much acidity.
