Because coffee has so many complex tastes and aromas, highly trained tasters play a vital role in coffee tasting to ensure coffee quality. It takes years of practice and experience to identify and judge coffee quality. Every respectable coffee company will have their own professional tasters; it’s the best way to guarantee the quality and consistency of every uplifting cup.
How we ensure NESCAFÉ® coffee taste and quality
After coffee is harvested
After harvesting, coffee cherries go through milling. This removes the outer fruit as well as the parchment-like skin around the bean. The end result is called green coffee, and quality-control at this stage is vital. Our experts work closely with our coffee suppliers in every country of origin. It’s the only way to make sure the coffee we use lives up to the world-famous NESCAFÉ® name.
Before coffee is shipped
We work closely with all our coffee suppliers through our network of six specialist coffee quality-control centres around the world. We also help coffee suppliers adhere to the latest food safety measures. Finally, our NESCAFÉ® professional tasters will thoroughly test the quality of our coffee before it is even shipped.
These days, professional coffee tasters are so well trained that they will all agree very closely on the exact characteristics of any coffee they taste.
In our factories
The beans undergo one last quality test when they finally arrive at our factories, before the coffee is used to make your favourite NESCAFÉ®. We also have professional tasting teams in every NESCAFÉ® plant worldwide. Satisfying their expert taste-buds is just the last of many quality tests that help guarantee the fresh, delicious taste of every cup of NESCAFÉ®.
This is how we’re able to have a lasting impact, working with our partners big and small to keep making your coffee better, tastier and more sustainable.
The language of coffee tasting
Expert coffee tasters need to understand the subtle differences between coffees. How has the way the coffee was grown, milled and roasted affected the final flavour? Did the type of soil the tree was planted in make a difference? Or maybe the way it was watered and fed? Even the type of bags the beans have been stored in could change that final flavour.
In fact, many experts in the coffee-tasting profession use a book called the Sensory Lexicon. It’s a bit like an insider’s guide to the strength of the different flavours in coffee. It lists more than 100 different flavours, and they’re organised into groups such as:
Floral, spices, sweet, cocoa
Fruity, green/vegetative
Roasted, cereal, nutty
There can be many flavours in each group. For example, the ‘sweet’ group of flavours includes molasses, maple syrup, brown sugar, caramelised, honey and vanilla.
