Types of Coffee Roast
There’s a lot that goes into your morning cup of coffee. In order for it to possess the taste that has you ‘ahhhing’ after each and every sip, it has to go through a unique roasting process which determines everything from the caffeine content to overall flavour profile.
Roasting is truly an art in itself and you’ll be surprised to learn how subtle differences such as a few degrees of temperature can alter the taste of the bean. Keep reading to find out all you need to know about the roasting process and the types of coffee roast you’ll likely encounter.
The roasting process
Interestingly, coffee beans aren’t just the wonderful rich, brown colour with the flavour and aroma we all cherish – they’re actually green to begin with and smell grassy! It’s the magic of the roasting process that we owe to the fantastic flavours and scents of the humble coffee bean.
Once the beans are put inside the drum of the coffee roaster and they begin to heat up, the process causes a chemical change in the beans as they’re brought to a high temperature very quickly. Then, once they reach the ideal temperature for that particular roast, they get cooled rapidly in order to stop them being roasted further. The whole process may sound relatively simple, but it requires a keen eye to ensure they’re roasted to the correct standards.
What’s the difference between washed and naturally prepared coffee beans?
Washed/wet-process and natural/dry process refers to the way the beans are prepared for the roasting process. Prior to roasting, the bean needs to be extracted from its many layers and this is commonly done in one of the previously listed ways. The natural process refers to when it’s dried in the cherry before de-pulping. Washed on the other hand is where they’re dried without the cherry, de-pulped and then they’ll usually be fermented to aid in separating the rest of the pectin from the bean and parchment, then finally, they’ll be washed and cleaned before drying.
Where you may not think it, this preparation to the roasting process actually does affect the taste! When dried naturally, you can expect fruitier flavours due to the natural sugars of the cherry, whereas washed offers more vibrant flavours, as it allows for the full taste of the bean to take centre stage.
