Some people prefer piston machines because they offer manual control and are attractive in appearance. Others find them difficult to operate and too slow in the warming-up process. Pump machines also generate enough pressure to make excellent espresso. They are easier and faster to operate than piston machines. Therefore, those who want the best of espresso usually opt for a pump machine.
Features vary, and some pump machines are considerably more durable than others.
So shop around before you buy. Stores that demonstrate their machines put you in the best position to make a solid choice. The Coffee You Buy Choose a fresh espresso roast. Ground coffee becomes stale within days, whereas whole beans will stay reasonably fresh for a few weeks. Therefore, if possible, buy whole beans and grind them at home, as needed.
