A little while ago I read a post on ‘Get Rich Slowly‘ where the guest writer was talking about his quest for the best and cheapest coffee. He went into exhaustive detail about the cost of heaps of different coffees, with his conclusion being that the Kirkland brand of coffee beans at Costco was the cheapest for him.
I was inspired to find out what the Frogdancer family was paying for our morning coffees.
Costco here in Melbourne only sells ground coffee beans, not the actual coffee beans themselves. This immediately knocked Costco out for the experiment, though a few months ago I bought a jar of ground coffee from them so I could keep reusing the container. Most people prefer to grind their own beans if at all possible. This might not sound like a big deal, but we here in Melbourne take our coffee very seriously indeed. Since the wave of Italian migration here in the 1950’s, Melbournians have grown up drinking espresso, capucchino and lattés like mother’s milk. In fact, our cafés make babychinos and pupperchinos so that the kids and dogs don’t miss out.
Oops, got off track. We in the Jones household grind our own coffee beans in the thermomix, (250g, speed 10, 27 seconds, for those who are interested), so I wasn’t going to pay extra for pre-ground coffee. It’s Frugal Friday, after all! This is where Aldi came to the rescue.
$11.99 for a kilo of South American coffee beans. In our house, we prefer the taste of the Brazilian/Columbian beans over the Italian ones, even though the Italian beans are $1/kg cheaper. Sometimes, you just have to lash out and spoil yourself.
As you can see, we use an Aeropress. Around $60 for the best-tasting coffee! It comes with what they say is a year’s supply of paper filters that are compostable… but read on. There’s a way around this.
After making a cup, the Aeropress people expect us to simply push the coffee grounds out into the bin along with the paper filter. We, however, refuse to be dictated to by The (Aeropress) Man, so we rinse and re-use our filters. During this experiment, I also tracked how long we were using each filter. We got 32 cups of coffee with one filter!
See the light coming in from the tiny hole in the middle of it? That was when this filter finally joined the coffee grounds that we save in a bowl to go out into the garden.
Brand-new filter vs 32 cup filter. You can buy a metal filter to replace the paper ones, but I won’t need to bother about doing this for YEARS!
Saving the coffee grounds is heaps easier with an Aeropress. Once the coffee is all in the cup, you just depress the plunger fully and the grounds are pushed straight out. No rinsing or fiddling about. Free fertiliser! Coffee grounds are high in nitrogen, which plants love.
Once a week I put the coffee grounds, tea leaves and any egg shells we’ve used into the thermomix and I grind them all to a powder, then I dig it into the garden. I love that I’m getting a second use from my morning coffees!
As you can see, out tracking of how many cups per kilo that we got was done with primitive, yet effective technology. A pen and paper beside the Aeropress and kettle did the trick.
$11.99 divided by 74 = 16c per cup of coffee.
This makes even the $1 a cup coffee that teachers in my staffroom buy each morning at 7/11 look like extortion!
Thanks to J.D Roth of Get Rich Slowly and John from ESI Money for producing the original post that this one sprang from. It was a fun little exercise to do and now that I know how cheaply I’m buying my morning cup of coffee, it makes it taste even more delectable.
