Do cold brew, it's the best.
You need a pitcher, a strainer, a blender or a coffee bean grinder, jars or cups, something to stir with, and some whole coffee beans.
The pitcher I bought from walmart for 5 dollars, it holds 64 oz has a locking lid with a kind of filter on the lid. The strainer I got from dollar tree, it has a handle. The blender I already had, if you get a grinder be sure to get one with a detachable cup that makes it easy to clean, the one I have is dog shit chink brand junk from amazon that I don't use and didn't bother to return. I already had mason jars.
The beans I buy are from Aldi. They're $6 for I think 12 oz, roughly same price as 8 O'Clock beans you can buy from Walmart. They're about the same, I prefer the Aldi beans though.
Step 1. grind coffee beans. I have a scoop that is 1/8th a cup, I do two scoops per cup, which is 1/4th a cup of coffee beans to 8 oz water, this is 66% the coffee to water ratio of Stok coffee for reference, which is 3/8s per 8 oz).
Get a coarse grind, if you using blender look up youtube videos on how to use the pulse setting for a coarse grind.
Step 2. take coarsely ground coffee beans and dump them into the pitcher. Add the water. Gently stir them so that all the ground coffee is submerged in water (you don't have to stir to dissolve like you would sugar, you just want all the coffee to be wet). Put on lid. Leave room at room temperature for 18-24 hours. If you want to put in the fridge it takes ~36 hours to brew.
Step3. Next day grab your [mason jar], makes sure it's large enough to hold the amount of coffee you have brewed, and your strainer. Hold strainer in place and pour the coffee from the picture into the jar. Flick the grounds into the trash from your strainer, rinse it off, then strain from the jar into your drinking receptacle. Rinse off the strainer and put it up. Wash your pitcher, wash your jar. Repeat step 1 for the next day's brew.
All in all it takes $10-20ish, depending on what you already have (obv not counting blender or grinder). This is my cheap setup, you want to spend more money you can get different kinds of setups but this is extremely effective so no point in that.
If you want hot coffee then a french press is another cheap option, I do not like hot brewed coffee myself. Cold brew I can drink black and it's an easily acquired taste.
