Home canning coffee?
I've decided i'd prefer to make my own coffee and can it to have on hand when i'm in a pinch then get a bottle of cold brew at the grocery to store in the car.
I wonder if anyone else has experience with this or has suggestions/oversights that could easily be made.
Off hand I would think to sterilize the jar, add freshly made hot coffee which should be about 200°F directly to the jar, let it self seal. I do wonder if this going to be enough for the coffee to seal past being perishable both from quality and safety standpoint.

For safe home canning in a water bath, you need the contents to have a pH below 4.6. Coffee typically has a pH of at least 4.8, so you need to either add an acid to bring the pH down or use a pressure canner to process the jars.
Moreover, coffee is full of volatile compounds that degrade relatively quickly when exposed to air. Canned coffee would likely degrade quite a bit within a few weeks, unless you use a process more similar to how beer is bottled to prevent oxidisation.
I honestly think it would be less effort to make a big pitcher of cold brew once a week and keep in the fridge for coffee related emergencies.

Can brewed coffee be canned?
I use a quart sized (32 ounces) canning jar to brew my coffee in and then store it in pint sized jars. You can use a plastic pitcher or container for this as well if you prefer. I like to brew mine in glass as there isn't the risk of tainting my coffee with another flavor this way.Can u can coffee?
You can use Mason jars to store coffee. The biggest thing to remember when storing coffee is that you need an airtight container. Mason jars are often used for storing jams which also require an airtight container to stay fresh.Can you store brewed coffee in a Mason jar?
After brewing, pour the coffee into a carafe and put it in the fridge. You'll have your own iced coffee, and the cold will preserve the flavor and aroma for longer than two hours. Take this to the next level with coffee ice cubes. Pour leftover brewed coffee into an ice tray and freeze.Canning: COFFEE!

You do not want to chill hot coffee. Its quality degrades rapidly when you do this -- like within hours.
Instead, you should make a large jar of cold brew and freeze it. Frozen cold brew can be kept for months or years. Storing it at room temperature is not feasible; you'll notice that commercially sold cold brew is mostly sold refrigerated, and the handful of "shelf-stable" brands are pretty uniformly terrible (Trader Joe's, I'm looking at you).
