Whelp, a few days down, I had to go down to base for a few days to administrate some stuff.
That being said: Project COFFEE is under way.
first experiment: pre-heating
pre-heating the water in a moka pot - does it improve the flavour?
Whelp, I gave it four days, two days of test, two of control. For the test, I boiled some water while grinding the coffee, and poured the boiled water into the boiler on the moka pot, then made the coffee as normal. For the control? I made it as I usually do, with cold/room temperature water going into the pot. All other things identical, at least as far as I can control them.
results:
1) the pre-heating did notably speed up the brew-time. It wasn't really a thing that I set out to measure, but while my usual batch takes 3-5 minutes or so to make on an electric stovetop, this took 2-3 minutes - but in all honesty I expected that.
2) the coffee was notably less bitter. I'm using a dark roast, from whole beans bought at a supermarket. It's not the worst stuff going, but it's definitely a couple months old by now, since I mostly only drink it on weekends. All that to say, any subtlety it may have had is more or less gone, which I suppose is particularly great for this application, as there is little other flavour to distract from any bitterness present.
3) while it doesn't make handling impossible, I WOULD recommend for one to grab a towel to handle the thermally conductive aluminium container with boiling-hot water in it.
On the whole, would I recommend it?
Honestly, if you hate bitterness in your moka pot coffee, it's at least worth a shot. That being said, it's not a night-and-day difference, but it's decently noticeable. I think I'll do it on days where I've got time to sit back and take my time with it. If I just need to gulp my coffee back, I'll just use cold water, it's not really worth the hassle.
