When you’re browsing the aisles, trying to choose a coffee blend at your local supermarket, it’s likely you’ve encountered numbers on the side of the jar, usually ranging from 1 – 10 or sometimes 1 – 5 . Many of us automatically assume that these numbers denote the coffee’s strength and therefore, the higher the number means the stronger the flavour.
How roasting impacts coffee flavour
The flavour of your coffee owes a lot to the roasting process. Before roasting, coffee beans aren’t like the ones you’ve come to expect, they’re actually green and possess a grassy scent. It’s during the roasting process that different roast profiles are developed and each blend is carefully crafted by master roasters, to ensure each sip is as delicious as the last. Generally, the longer beans are roasted, the more natural oils that are released from the coffee beans, giving them a stronger and more bitter taste.
