coffee log

Now that we have a scale and a timed, setting-delineated burr grinder, it's time to keep some records of the settings used and the results.

My machine for these records is a single boiler unit, a Breville Cafe-Roma with a pressurized (2-wall) portafilter basket, and my grinder is a Breville Dose-Control Pro, which has a pauseable timer and adjustable coarseness-setting, and can feed directly into my portafilter.

I've wanted to pay nerdy attention to the coffeemaking process for some time, and while the coffee we've been making has been good, I have the feeling it can be better -- and more importantly, that it can be consistently good. I'm looking forward also to developing a better eye for the weights of different amounts of dry/wet coffee through this, too.

a note on wet weights

The 'wet' weights may look unusual to any serious baristas out there -- why am I pulling these espressos so long!? It's because at the moment, I'm not pulling 'real' espresso shots. The Cafe Roma comes with a double-walled portafilter basket, aka a pressurized basket. It has a single small hole in the outer wall, and the traditional many-holed wall inside. The two act together to allow a lot of coffee to pump out very quickly, and make it (as far as we know) so that a classic espresso can't really be pulled, i.e. in a 1:2 or 1:3 ratio by weight.

The coffee still tastes quite good and is similar to an espresso shot, but would not likely satisfy a true coffee snob. Fortunately I'm not one yet! It is an interesting compomise, because the crema created is always very pretty, the coffee tastes decent even with much more coarse grinds than you can generally achieve without a decent grinder, and the results are overall, pretty forgiving regardless of over-or-under-pulling or how you've dialed your grind.

When we started using the machine, we wondered about the large amount per pull, and it took a while to realize we weren't really doing anything wrong! Still, we'd like to make 'the real thing', and take better advantage of the finer settings available on our grinder, so we found a single-walled portafilter basket online, which has just the wall with many holes, and thus is not pressurized. Hopefully it fits right and our coffee-game will be upped again soon. :)

mug weight: 295g, portafilter+basket weight: 210g

After this coffee, I did some reading and bought a depressurized portafilter basket online. The ratio of 16g dry to 126g wet is absolutely not what I apparently should expect from espresso
