drip tastes rather lame compared to espresso machinated coffee, capsules (nespresso and others) can be good but the capsules are rather expensive, espresso machines for grinded coffee are fine, espresso automats with built in grinder get you coffee by the push of one button and make a jet noise but are more expensive as for the machine, a cool low cost alternative in case you want to avoid drip machines are stove tops which were also the first and “original” italian espresso machines and are still commonly used and make somewhat cooler than drip machine coffee . . . stovetops start at 15 bucks for aluminium ones 10 bucks or so more and you can get the preferable stainless steel ones . . . stovetops for hundreds of dollars are available too though but one for 30 or 50 should be fine . . . stovetops you simply put on a stove like a cooking pot . . .
as for the electric espresso machines their designs vary so much that it can be hard to tell at first sight if they got a grinder built in . . .
soaking coffee in water somehow already gets you coffee (drip machines are just a convenient way to do that) and like a “turkish” style coffee is drank without even filtering out the grind so anything is possible and all of it easy to prepare I would say . . . a matter of taste and funds of course . . . espresso machines don’t let coffee soak but push water through rather fast with high pressure which makes for great taste and good looking brown crema foam too . . .
as for preparation method an espresso shot is the healthiest and got the lowest caffeine even though it tastes the strongest whereas decaf is the unhealthiest and filter drip got the most caffeine ending up in the cup . . .
coffee includes caffeine and other ingredients that upset some peoples stomachs and are untasty and the longer the coffee got contact with water the more caffeine is washed out and later those not so agreeable other ingredients get washed out too . . .
which is also the reason why the original “verlaengerter” (full cup of coffee) around here got its name and should be made of an espresso shot and filling up the cup with plain hot water rather than just letting the espresso machine go for longer to fill the cup . . .
coffee is awesome I hope this helps having a cup is greater than all the theory but since I got a cup of coffee covered and am on the internet in the morning just now on a day off I got the time too . . .
