What is the 30 second rule for espresso?
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 double shot can be acheived by repeating the single shot, or using a double basket (holding 14grams of coffee) but extracting in the same timeframe (30 seconds) and producing 60ml of coffee.For a single shot: Use 7-9 grams. For a double shot, grind between 18–21 grams of coffee into your basket.Perfect Your Timing Timing is everything in espresso. For a double shot (approximately 2 oz), aim for an extraction time of 18-22 seconds. If your shot pulls too fast (under 18 seconds), you may need to adjust the grind finer or increase the dose.
