Turkish Coffee and Arabic Coffee are pretty similar but the difference between Arabic Coffee and Turkish Coffee is that Turkish Coffee is made without added spices.
Turkish coffee is basically plain coffee using roasted and finely ground coffee beans without the use of spices to flavor the Turkish Coffee.
The Arabic Coffee is made also with heavy roasted coffee beans but has added spices such as Cardamon to give the Arabic Coffee flavor.
They are made in a similar way but the Arabic Coffee usually has a better taste to it than Turkish Coffee.
Turkish Coffee is also in some peoples opinion and even my opinion to be stronger than regular coffee.
