I have to mention my clients (I’m an eldercare provider). Shortly after I met them, I told them, “We are meant for each other. You’re the only people I know who have as many different types of coffee and olives as I do.” 
They have and use regularly: a Keurig, a Tassimo, a vintage beaker-shaped thing that goes on the stovetop (can’t remember what it’s called at the moment), a French press, and an espresso maker. They also have, just in case, a moka pot or three, a spare French press, and several small items that I think you’d use to make espresso by hand. They have at least two grinders but use their new burr grinder the most. And they must have 20 different types of coffee. They may only drink a cup or two per day, but they are quite serious about their coffee.
Interesting, thanks.
One. A basic 12 cup hot coffee maker. We don’t use it. We cold brew our coffee. Raises the caffeine levels through the roof whilst eliminating almost all of the acidic bitterness associated with a cup of coffee.
I have zero coffee-making devices and never drink coffee.
Love this! How fortunate you’re their caregiver and not Snowboarder. 
No wink necessary. I made coffee twice in my life, when I was the overnight DJ at a country radio station. I figured I’d try and swallow the vile stuff because, ya know, that’s what people do at work and the caffeine would help me stay awake. I never managed to drink more than a small sip and the next guy who worked the shift after me flat out told me to just stop making it or throw it out before he got there. I think he described it as tasting like “burnt mud”, which is pretty much what coffee tastes like to me in general.
I do love the smell, tho, especially in the morning.
A Behmor 1600 to roast
A Capresso burr grinder
A Technivorm Moccamaster to brew via drip (my usual brew).
Three sizes of French Press.
A Capresso drip, a French press for the RV, and a large bowl for cold-brewed. And a Breville burr grinder.
I have a Keurig for daily home use, a big (maybe 40 cup) percolator for parties, and a metal stove-top percolator for camping.
Forgot about the grinders - we have a Mr Coffee adjustable automatic grinder, and a Hario Mini Mill ceramic burr hand grinder. I bought the latter after realizing the impact of a power outage on making morning coffee.
We have a coffeemaker, but it’s now in the basement. I never touch the stuff and my wife discovered that instant coffee is fine for her for the occasional times she drinks it.
Surprisedf that I actually have three - electric drip machine which I use daily, sometimes a couple times a day, easy and convenient, percolater 9mostly though not exclusively for camping, and a briki for making greek or turkish coffee.
The one I use is an Aeropress, but I also have an old four-cup drip coffee maker salvaged from my parents when my mother bought a new one, an ibrik that I bought in Turkey with a Turkish coffee service, and a very old stovetop percolater I’ve never used, also salvaged from Mom and Dad, because it is a beautiful bright blue enamel and looks nice.
I have a lot more teapots, some very nice.
Just this Viking which I love.
One small coffee maker. I haven’t used it in at least six months. (I never buy coffee grounds, but somebody gave me a packet.) Once in a while, my mom will use it when she visits. When I want coffee, I either go to a coffee shop or make it on a communal Keurig-type machine at work.
One ancient Mr. Coffee. Two reasons: ease of use and cheapness of supplies. I only need to buy coffee filters every few months and they cost only $1.50. And I buy cheap generic coffee for about $5.49 a can. I also brew full pots and am willing to leave the coffee sit in the pot and microwave individual cups when I want some. I guess you could say I’m a coffee Philistine. When it comes to coffee, the least work I have to do for it, the better. It’s just a beverage to me like any other.
Zero. I don’t drink coffee.
When the time ever comes when I anticipate I might have an overnight guest who would like a cup in the morning, I might consider getting something cheap and simple. But I doubt that’ll be happening anytime soon.
We have a Superautomatic that is our daily workhorse. For emergency backup, and as a legacy of pre-Superautomatic days, we have two French presses and a gold filter.
We use a Saeco super automatic every day Philips - United States | Philips and a French press to make cold brew ice coffee in the summer.
One coffee grinder. An espresso machine that is used daily. A french press, also used daily (for the coffee we bring to work in thermoses). Two single-cup coffee drip thingies for Vietnamese coffee. An ibrik. A stove-top moka pot. A conventional drip coffee maker. There’s also a big coffee urn (not huge, but definitely not a single-family unit - maybe 20 to 30 cups?) that is down in the basement somewhere. So that’s nine.
We also gave away a couple other coffee making devices recently.
