The coffee of Brazil
Brazil is the largest producer of coffee in the world, producing about a third of all the world's coffee. So much so that roasting a good quality Brazilian coffee to a medium roast will give you a very recognizable cup of coffee: it's the coffee you'll drink at your local donut and coffee shop.
Brazilian coffee is also used as a base for espresso blends (as well as many drip blends). It is an overall inoffensive, easy to sip coffee that has a lot of body, with sweetness and nuttiness. It provides a good base and mixes well with anything else. Want more sweetness and acidity? Add a Central American to the mix. Want to add spices, fruits and a dark roast taste? Throw in a Kenyan, or a Sumatran for added depth and earthiness.
Brazilian coffees are best roasted to a medium roast (City to Full City).
