Dialling in is crucial
Single Origins differ from region to region so dialling in your espresso is crucial to experience the espresso’s true complexity and delicious flavour. A coffee from Kenya may have floral and citrus notes, whereas a coffee from El Salvador may display more hazelnut and chocolate flavours. This is due to many reasons, including the botanical variety of coffee, how it is processed at origin, and how it is roasted for the consumer.
Of course, how you choose to brew your single origin coffee will also affect the flavours you notice in the cup. For the purposes of this blog, we will be focusing on espresso brewing.
For any espresso recipe, dose will always remain in line with the basket size you are using. So if you are using a 20g VST basket in your portafilter, you will dose 20g of ground coffee. The yield and time for each single origin may need some tweaking.
We recommend a 1:2.25 ratio. For example, a 20g dose should yield 45g of espresso. This is always a good place to start, with a shot time that runs as long as possible without the coffee tasting bitter. When your espresso begins to taste bitter, try making the grind coarser and the shot time shorter.
Lock it in
Once you have your ratio locked in, start making adjustments to your grinder to get the shot times right. We find the best tasting shots often run between 27 and 33 seconds; this may vary according to the origin of the beans and the basket size you’re using. Always let flavour balance be your guide.
Learning to identify the nuanced flavours in different coffees is a great way to develop your palate. Dialling in your coffee is fun and interesting, connecting you more to the beans you’re pouring into espresso. Single origin beans offer consumers the perfect opportunity to experience the many flavours that coffee has to offer.
