of making coffee of pouring boiling water on ground coffee in a glass
This is called french coffee.It is the most usual,very weak and sometimes changes your mood(you might get sad etc,it causes feelings).
Then there is italian coffee espresso which is supposed to wake you up instantly by being vey strong(but its influence lasts only 1-2 hours then you want again) and cappucchino(which is bigger quantity,more flavoured like chocolate and less strong with some mood effects).
Then there is turkish or greek coffee as we call it here which is weaker than espresso but stronger than french.This coffee has the effect to make you talk too much,it is popular among women who visit each other to gossip around(and maybe then tell their fortunes by looking at the coffee remaints on the cup typical for this kind of coffee).
Then there is the king,the frappe the strongest coffee if done right but very few manage to make decent frappe(a lot depends on the analogy of water,the duration of shaking,the kind of coffee used etc).The frappe is ideal for fast work but it may make you look like frenzy or crazy if overdone.It is commonly used by students to stay awake at night studying before exams or during exams to be able to remember stuff.It is also the commonest drunk by youth in cafeterias because it provides excitement being able to stay and enjoy for hours(typical greek habit while the European-Italian drinks his espresso i minutes and leaves).
Relatively new trends are fredducino,freddo which taste awful in my experience and make you feel like sh1t.
Then there is ice coffee which makes you feel like sh1t(hammered) for half an hour but then causes a higher level of energy.I use it in clubs sometimes when I want to pick up girls and need higher energy levels and alert.For sure chronic drinking of ice coffee cannot be recommended it is the most likely to cause insomnia,stomach problems etc.
