You should restrict the pour volume (the amount of water flowing through your capsule during the extraction process) in order to get the optimum strength of coffee that each specially blended capsule is designed to deliver.
Most Nespresso® or Nespresso®-compatible machines have a programmable pour volume setting (check manufacturers instructions for your machine to learn how to adjust pour volume settings) which may have been deliberately or inadvertently adjusted during use.
This most often results in longer-pour programming for your machine rather than a shorter pour.
Espresso capsules, just like commercial espresso machine porta-filters or ‘handles’ used by a professional barista, are designed to create the optimum individual espresso with between 5-7grams of finely ground coffee for each individual espresso.
A text book single espresso should be just 1.25 fl.oz of liquid. If you prefer a double or ‘doppio’ espresso you should really use 2 capsules to pour a 2.5 fl.oz drink (just as a professional barista would use a double-shot of ground coffee in a double porta-filter) rather than to infuse twice as much water through one capsule, as this will only dilute and weaken your premium quality coffee taste.
In fact the coffee connoisseurs’ choice is to order their espresso ‘ristretto’ (restricted) poured, at just 0.75 fl.oz to truly experience the finest and purest taste attributes and characteristics of each blend, and eliminate any of the bitterness that is experienced in coffee which is extracted for longer.
Select the coffee blend that best suits your taste preference according to the strength or intensity rating on the package – Caffesso blends range in intensity from 3 to 12 – and there’s a reason there is a choice: because everyone’s palate is different.
