Coffee is one of the most popular drinks in the world and is brewed and prepared from roasted coffee beans. The highest quality beans available fall into three main types. Arabica beans are full of flavour while Robusta beans have higher caffeine content and are generally used in stronger coffees. A blend of Arabica and Robusta produces a strong coffee but doesn’t sacrifice on the flavour too much as far as taste goes.
Some producers use blends sourced from different locations, as long as they are all Arabica and the blends are created by an artisan roaster, the taste will be much better than cheaply mass produced coffee. The different flavours depend on your personal preference, a specific flavour for example, something deep and dark; you might want to consider going for a single origin coffee from Brazil. A blend would have a more complicated flavour. The best thing to do is experiment with different coffees until you find one you like.
For the most flavourful cup of coffee possible, buy your beans whole and grind them yourself. Grinding beans in this way is a step in the right direction and is a crucial part of the brewing process. Being in control of the grind size has a huge impact on flavour, the aroma and taste obtained from freshly ground coffee is amazing.
Coffee connoisseurs would prefer whole beans for a better coffee experience, but for ease and convenience you are more likely to choose pre-ground coffee. Unfortunately, because bags of coffee at the supermarket are roasted weeks, may be months in advance, it will have become stale and quickly lost most of its natural aroma and flavour. Peak freshness is just one to two weeks after roasting and pre-ground coffee loses most of its natural flavour in just 20-30mins.
The main difference between the two is freshness, flavour and scent. Grinding whole beans a few moments before brewing, will produce a cup of coffee that tastes more complex and fresh compared to ground coffee.
