I drink 2 cups of coffee each morning. I more interested in getting good results out of currently-available ingredients rather than seeking out the best cup of coffee humans can make.
I generally use water right out of the fresh tank unless it is excessively-chlorinated or something; in that case I would use Brita-filtered water.
I typically buy whatever coffee is on sale at the store, and have had good results from Chock Full ‘o Nuts, Folger’s, Maxwell House, etc. I shop at discount grocery stores when I find them and sometimes they have out-of-date whole beans for $1/lb or whatever. I grind them up in a $2.99 thrift store Krups grinder and they smell and taste fine. I suspect Whole Bean People are a little picky and not willing to buy beans past their prime.
I use 18:1 water-to-coffee by weight, or ~26g of coffee per 16oz of water
When traveling solo I typicaly use a Melitta pour-over I got on clearance for 50c at a grocery store (win!). I brew directly into the mug.
The dripper works best with #2 cone filters but I use plain basket filters because they are so much cheaper.
When making coffee for myself + a guest I use a Stanley 6-cup camping percolator. It’s well made and I expect many good years of service from it.
The dripper might make better coffee (maybe) but percolating coffee is a better sensory experience. And you also have control over relative strength by varying perc time.
As with the dripper, I don’t use the proper filters (3-1/2” disc-style) but rather just stuff a basket filter down in there. Wetting it a bit with the sprayer helps control unruly basket filter material.
I started out with a french press. Superior coffee IMO but I found cleanup in the small sink to be a PITA. Stanley makes a stainless steel camping french press for those who don’t mind the cleanup duties.
