WHAT’S EXTRACTION?

When hot water comes in contact with ground coffee it begins what’s called extraction. This is the process of extracting flavour compounds from the dry coffee and dissolving them into hot water. All coffee beverages are part water, part dissolved coffee.

CONTROLLING FLAVOUR

When dialling in, it's best to start with a dose that will always remain the same. Then get the type of flavour right by balancing under & over extraction through manipulating your yield. Then work on getting the desired intensity of flavour by grinding finer or coarser to manipulate your contact time.
