"Many people become sentimental when they think about percolators, often recalling childhood memories and the smell of coffee in the air in the morning. Nostalgia aside, percolators are by far the least well-regarded of brewing methods. The water is overheated, the brew overextracted (only water should be spread over coffee grounds, not already-brewed coffee), and the percolating action dissipates the complex, volatile compounds into the atmosphere. This is why people often recall that wonderful aromas: the aromatics that should be in the coffee are instead cast off into the atmosphere." -- Scott Rothstein, The Coffee FAQ (Chapter 3: Brewing Techniques)
[Include me among the folks with fond childhood memories of percolators. It almost makes me want to get one just to make the kitchen smell right, and use some other method for preparing coffee for drinking. But that'd be wasteful. (Then again, if I only did it when I really wanted to set the scene for an impressive and comforting breakfast for an overnight guest with the same mental associations ... Make my house feel and smell full of "This Is Home, You Belong Here" triggers ... Not that such subtle psychological manipulation ever occurs to me, of course, nuh uh.) OTOH, when I need a mood-lift for myself, it might make a useful happy-place sensory trigger.]
