Subject: Aluminum boilers
Most coffee writers warn against the aluminum percolator, but would the same
warning apply to the aluminum boiler in pump espresso machines? Do minerals
leach out in the hot water, or is it the water/coffee combination that they
are concerned with. I imagine that I can taste a difference in beer or soda
between bottles and aluminum cans; my wife thinks that is nonsense. Can
anyone discern an aluminum taste in espresso made in a Gaggia aluminum
boiler as compared with, say, a brass boiler in a Rancilio Silvia?

You prolly can. I can taste the difference between aluminum can Coke and
plastic bottle Coke.
My wife didn't believe me until I passed her blind taste test.
Ha! And she thought I was bullshettin her. Now she obeys!!!!

You can certainly tell the difference between beer in bottles vs. cans,
but that has nothing to do with the chemistry of the materials, and
everything to do with their physical properties. The amount of pressure,
the light reaching the beer (which very quickly oxidises the hops component),
and so forth.

Howdy Harry,
I use many machines as my mood dictates: Gaggia Espresso, La Cimbali, Nuova
Simonelli, La Pavoni, moka pots, & ??. I believe that I've a pretty well
educated palate & if the temp is spot on and the coffee & grind are the same
I can't tell which machine made what. Of course - YMMV.
