How many seconds should my Breville grind for?
Noting that a great tasting espresso can take anywhere between 20 and 40 seconds. Grind size – the granularity of your coffee also plays a crucial role in achieving a good 25-30 second extraction time. The 30-second extraction rule suggests that a well-balanced espresso shot should take approximately 25-30 seconds to extract when using 18-20 grams of ground coffee and yielding about 30-40 milliliters of espresso.A 1-ounce espresso shot, by comparison, packs roughly 63 milligrams of caffeine; a double shot contains around 126 milligrams, exceeding the buzzy strength of a cup of coffee. So, roughly one-and-a-half espresso shots deliver the caffeine equivalent of an 8-ounce drip coffee.How Many Espresso Shots in a Day Are Safe to Drink? Espresso is small but strong. For most adults, 4 to 5 espresso shots a day is the limit. Go over that, and you risk jitters, anxiety, or worse.
