My significant other doesn’t care nearly as much about coffee as I do, so we always have pre-ground supermarket coffee at home. Tastewise, it’s usually rather dull and bitter because apparently, that‘s what people expect coffee to taste like around here.
I wonder if there is a method/recipe that can compensate for those flaws. The Aeropress is pretty versatile, so going for lower temperatures and/or shorter extraction times comes to me as a natural first step in this investigation. Doing a pour over with this stuff feels like I‘m wasting precious V60 filter papers though tbh 😄
Any further suggestions? I own a V60, an Aeropress, a cheap drip coffee machine and the (in-) famous IKEA french press. My kettle only allows for adjustments in 10°C steps, but features a temperature display, so I can go reasonably precise on that end.
I have a 1L french press jug that I fill with 80g of coffee, coarse grind (34 on 1zpreszo JX) and top with cold water making sure all the grounds are wet and stirring lightly to make sure they're all wet. I leave it in the fridge for 12-18 hours and filter through the mesh. I dillute with hot water or just microwave it after dillution if I'm too lazy to boil (blasphemy I know). I sometimes mix it with tonic water or ice and drink chilled.
Make sure to pop it in the fridge. Room temperature extracts the acids somewhat which isn't to my preference.
That’s the neat part, all you need is a big jar, 24 hours in the fridge and filter patiently… the filtering isn’t really slow but you usually make a bunch.
Ratio of coffee to water is really the only tweak you can make. I used to use a whole 14OZ bag at a time and I’m not sure how much water anymore… I just used the same large glass jar every time, so there was more eyeball than measure.
It’s a very forgiving method, you can leave it in for 48+ hours, but 24 is the minimum. Once you filter it it’s good in the fridge for a week.
Honestly, your ingredients are going to far surpass any brewing method. I've brewed cheap coffee in my Chemex that didn't taste very good and quality coffee in a hotel in-room Coffee machine that tasted amazing.
Good Beans + Good Water gets you like 70% of the way to good coffee.
Yeah, I‘m aware. That‘s the reason why I’m reluctant to use my good consumables in aimless experiments.
What I‘m looking for really is some way to deal with overly bitter grounds, and I know the basics of extraction. Maybe someone just happens to have gone down that path already and can say something like „Put them in a french press, 50 grams per Liter, water not hotter than 85°C, steep for two minutes max“ or so. 🙂
If I were to provide a suggestion, I would start with fresh grinding your coffee from beans. You can get a pretty cheap manual grinder for like $20-30. I don't remember the name of mine (it's generic) but it was like $30 on Amazon and is great when I travel.
Next time you're in a coffee shop, grab their cheapest blend. Coffee shops, in my experience, have fresher beans than the grocery store, especially if they roast their own coffee.
It doesn't have to be the $26 organic single origin, just something that's been roasted more recently than 6 months ago. Maybe you'll be able to convince your S/O to get some better coffee in the future.
I do grind fresh usually. It’s only that we got this stuff at home already and I hate wasting coffee when it’s going stale just because no one uses up an open bag, even if it’s bad coffee.
As a bonus, knowing how to get anything remotely decent from these raw materials, it would enable me to do so when I don’t have my nice things with me, be it at work, at my friends & family’s homes or on vacation.
Immersion brews are generally more forgiving than percolation, so lean into that French press or Aeropress. The V60 will probably just highlight the flaws.
I went french press because it is so forgiving. Put ground beans in container, pour over water and let it sit. You can of course go fancier, measure things here and there. But you'll get very far with very simple techniques, or no technique.
Speaking of grind fineness it's also very forgiving there as well. The finer the grind the shorter steep time is needed. I saw a video some time ago about this (there were a well spoken snob whose name I've forgotten, will find later) and the conclusion was that pretty much any grind will make good coffee.
I don‘t mean to put you off a wonderful vintage grinder, but isn‘t grind variance considered bad? If with that you mean, using the a more technical terminology, heterogeneous particle size distribution. Because that would result in both over- and underextraction happening in your brew at the same time.
Again, if everything works fine for you, don’t let me try fix a problem you don’t have.
Check my other comment. I grind using an old timey grinder. Not sure what condition the grinding parts are in as I don't know how they should look new. So your pre-ground should be fine. Probably with a but shorter steep (2-4 minutes?). You biggest issue may be oxidation of your coffee.
You do know you can fake a french press by just putting water and beans in a container, let it steep and once done pour through a fine sieve.
I'm a robusta drinker, anytime I'm stuck with arabica I use a pinch of salt and as you say, it does wonders. Livens it up and cuts through the acidic taste some arabica tends to have.
Cold brew, followed by French press. With cold brew you want a coarse grind but it doesn't really matter THAT much compared to pour over. You just dillute to taste. I do it in a french press so it's easily filtered. The french press is also forgiving. I've oversteeped by 5 minutes and the coffee is still drinkable. Lately I've been mostly drinking supermarket generic Arabica bean brews since I'm on a tight budget but I wouldn't do cold brew with specialty coffee anyway!
Did the cold brew in a french press, and it was great! After 18 hours of steeping, it was perfect (given the temperatures outside). After that, it went bitter again, but also, the ratio of coffee to liquid had shifted quite a bit as I started to drink the coffee without removing grounds.
Filtration also was great, no sediment whatsoever.
There is a video from Lance Hedrick for the aeropress on making old coffee taste passable. I know you can't control the grind size, but try it out if you already have the aeropress handy.
French press as stated and aeropress will give you the most consistency across grind sizes. But a burr grinder is the most important piece of equipment for coffee. I was sceptical uuntil i got one. Surely the difference isn’t that big? Boy was I wrong.
Consider a hand grinder, even something cheap like a Harrio annoying as it is to use, it is passable at like 20 bucks. It was my first grinder, it did the job, but adjusting the settings is limited and annoying and it took forever to grind a cup, I quickly bought a Mignon Chrono.
If this isn’t an option, then maybe consider buying preground in smaller batches from a local place? The place I order my beans from offers to send them ground in a couple of generic preset sizes.
But the problem is not only the quality of supermarket coffee, and the preset grind size, it is also that ground beans will oxidise much more quickly and even when vacuum sealed, the moment you open the bag it will start to deteriorate and quickly. I would possibly even consider a blade grinder over buying pre-ground coffee, especially supermarket coffee.
I do own a hand grinder and make nice pour overs and such most of the time. Thing is that the rest of my family hasn’t found the same joy in coffee as I have (yet), so they continue to buy the awful stuf. For many reasons, I’d like to make the best of that sort of raw material.
If you have a grinder, why not just order separate beans for yourself? Or even supermarket beans? Beans are always higher quality and don’t deteriorate as quickly as ground coffee.
If you must use pre-ground, do either of the immersion brew methods. And all you can do then is tune your brew temperature, experiment with coffee to water ratio and brew times to taste, you can google generic advice on how to do so.
If you want to do pour-over, you just have to find a brand that comes in the magic grind size for your filters and do the same as above.
Personally I think a cooler temp aeropress is the way to go. Cold brew is a good idea too, but if you are looking for your morning cup of coffee, you might not want cold. You can steal a trick from the beer industry and add some calcium chloride to the coffee. Chloride ions suppress the "harshness" of bitter tastes. Some people add salt to their coffee to get the same effect, but then you get the saltiness in addition to the chloride ions.
Really, I think for the most part, the beans make the biggest difference, so there's only so much you can do. When I end up drinking mass market coffee, I'll sometimes just add cream. There's a reason so many people do.
I second cold brew. I don't know how you do yours, but Toddy is a cheap system and brews coffee concentrate (~3:1). I do a pound of beans at a time and keep the jar in the fridge. When I drink it, I fill a cup about 1/3 full and pour boiling water from a kettle to fill the cup. One brew lasts about a week.
With the right system, there's no need to drink cold brew cold; and I agree that as a method, it's more forgiving of bean quality. It was a good suggestion.
That’s just the sort of gadget I’m very likely to buy, please don’t point me to that kind of stuff! 😄
I might implement a routine though where I always have some cold brew concentrate available in the fridge in case I need coffee and can’t put in the time & effort of a pour over etc, so good suggestion!
Our water always came across to me as acceptable, but I wanted to measure the aspects most important to coffee non the less anyway. I’ll keep your suggestion in mind, thanks!
My parents drink mediocre pre-ground coffee. I left a single-cup French press at their house so I can have better tasting coffee whenever I visit. It doesn't require advanced prep like cold brew.
Pour over is probably it. I got my mum, who prefers simple solutions, a steel filter. It's got little holes in it. Got a v60 as well. It's done really quickly and is very forgiving with grind size. Most demanding step of the whole process for her was pouring it over in circles.
Still pulls out the percolator sometimes though. Doesn't like standing over the stove doing nothing. Tastes bitter as all hell but hey, she's done her coffee that way her entire life.
Others have suggested that pour over would even emphasise the bad taste. Hm, I might conduct a single cup experiment one day none the less.
But yeah, in my family, I also have those people who actually seem to want their coffee taste as bitter as the 8th season of Game of Thrones was. Offering them anything else feels like throwing pearls before swine.
