Roasters turn green coffee beans into brown or black beans for coffee. Large-scale roasters use machines to create different roasts, while home roasters can use simple or complex machines. Good beans are necessary for good coffee.
Roasters can be defined in two ways. Each definition refers to the process of taking ripe green coffee beans and turning them into brown or black coffee beans, which are then ground and used to make coffee. The first definition of roasters is that they are professionals who obtain beans in large quantities and devise roast times to achieve certain types of tastes. The latter can refer to a number of different machines, or sometimes the people who use them, that can be employed in the home to create much smaller batch coffee roasts.
Large-scale roasting is considered an art form by many roasters. Roasters must first obtain a supply of good quality beans and then use large roasting machines to create what are known as different “roasts”. These are packaged and sold on the spot, or they can be shipped to a number of companies where they are sold directly to customers in bean form or prepared into delicious coffee drinks.
Some roasters work in the background and the location of the facilities is not widely known. Others like Starbucks have perfected processes that are so popular, that the exact styles they produce could be roasted to specific specifications in each facility the company uses, before the coffee is shipped to Starbucks and other locations. The experience level of reputable roasters varies, but when these people or companies feature specific popular roasts, it can be a major selling point for coffee.
The other type of roasters, as many people would like to try this art at home, are simple or complex machines, available in a variety of price ranges. It is theoretically possible to roast coffee at home in a skillet, preferably cast iron, on the stovetop or in the oven on a few baking trays. A convection oven is typically recommended as it tends to circulate the air and cook the beans more evenly. Home roasting was once the standard when it came to making coffee, so this is actually a throwback to more classic coffee brewing.
Comparisons to yesteryear might end with many of the modern coffee roasters available. Some of the fancier ones cost well over two hundred US dollars (USD) and look slightly like rotisserie or toaster ovens. Others are made with circulating drums that keep the beans moving as heat is applied. Undoubtedly the least “advanced” of these machines, usually costing around $30 USD, is a stove top model, very reminiscent of a stovetop popcorn popper. People turn a handle to turn the beans as they cook over the flames, ensuring even heat distribution to each bean.
All available roaster models can roast about a pound to a pound of coffee at one time, and each type may require more or less oversight. Piano models usually require constant supervision and action, while some types of drums simply require you to set a button for your desired roast. Experimentation is required to get the most favorable roast, and professional-type roasters remind their fellow connoisseurs that good roast coffee can only come from good beans. So people would have to do some shopping to find the high quality fresh coffee beans for sale.
