You see... With Espresso, the water goes thru the Grounds way too fast to pick up as much as Drip Coffee Makers.
The water in Drip Coffee has more contact time with the Coffee grounds. Hence more caffeine.
I found this out long time ago... I was in the Espresso trap also... Sure it's strong, but it is Weaker...
Believe it....or Not
up to you...
The two processes are very different. Drip coffee uses a very course grind. Espresso uses an extremely fine grind. For drip coffee, the water merely passes through the grinds via gravity. For espresso the water gets injected into the grounds at extremely high pressure. The time spend during extraction may be shorter, but the process is much more efficient.
