"Singles or Doubles?
Espresso comes in two sizes: single and double. A single is a 0.6 to 1 ounce espresso made from 6 to 10 grams of coffee; a double is a 1.2 to 2 ounce espresso made from 12 to 20 grams of coffee. Singles and doubles take the same amount of time to pull, roughly 25 to 33 seconds, and the coffee flavors and aroma should be the same."
???0.6~1??, wow, ???, ????18~30cc, ???36~60cc.
