I am making the very first steps in coffee world and decided to start with a simple coffee maker. After reading the forum I realized that the simplest machine that is able to brew a decent coffee is stovetop Bialetti. However I do not know which one is better one with aluminum body or one with stainless steel. Aluminum one seems to be more traditional but steel one should add less taste to coffee. Could you please give me any suggestions on which coffee maker to buy? Many thank in advance for your comments.
