Espresso machines are extracting espresso shots at 9 bar pressure. However, in old fashioned machines the pressure was - during extraction - decreasing from around 9 bar to 6 bar. This decreasing of pressure is better for the espresso ground, the result is way more flavorful - given high end espresso beans like our Il Caffe Manaresi esrpesso beans. Espresso machines with vibration pumps need a higher extraction pressure around 11 bar, compared to rotary vane pump espresso machines, which run at 9 bar. The decreasing pressure for extraction is available with artisan double spring lever espresso machines or modern paddle espresso machines. Those machines (double spring lever and paddle machines) are coming with a price tage of more than $ 2,000 easily.
