Understanding coffee bean density is crucial for defining your roast profile and avoiding roast defects – but it’s not easy to measure. Fortunately, Boot Camp Coffee have a hack.
What Is Coffee Bean Density & Why Does It Matter?
Coffee bean density – which you may also hear referred to as “hard beans” and “soft beans” – will vary greatly depending on many factors. But in most cases, denser coffees ripened slower, developing more sugars and complex flavours while doing so. They were probably grown at a higher altitude and in cooler temperatures. The result: a (generally speaking) sweeter, better coffee.
What’s more, denser coffee beans react differently to being roasted. Harder beans are more resistant to heat, and can be roasted at higher temperatures. Roast them as you would a soft bean, and they might bake. Roast a soft bean like a hard bean, on the other hand, and it might scorch.
How Do I Measure Density?
It’s clear that density is important, but that doesn’t mean it’s easy to know how dense your beans are. So take the guesswork out of coffee roasting with this hack from Boot Camp Coffee. In this quick clip from a roasting workshop, an instructor explains an easy DIY way to measure bean density in relative terms.
