I won't add any sugar or milk, just strong plain black cold brew concentrate that I would cut with 50% with RO filtered water.

Alos, I have no experience in canning or bottling, and would prefer to go with cheapest and easiest option.

Mason jars or stainless steel water bottles.

Thats how the wife does it. Makes the straight black, pours into mason jars, sticks in fridge. lasts her a couple weeks at a time at least, she always finishes it before spoilage.

Find the bottled water with the strongest resealable design and use those.

I would like to try some options like capping glass bottles or even canning (probably expensive equipment wise), so I want to see what are the procedures to long time preservation of those. Who knows, might even start a cold brew coffee business, there's none on the market here.

Canning is an interesting enough idea that I looked up some advice on it.

Normal coffee isn’t acidic enough for the easiest canning methods (water bath or steam canning). Cold brew is less acidic than normal coffee, so you might have to add a squeeze of lemon juice. But really, how long do you need the coffee to last if you’re going to drink it regularly?

A simpler solution might just be to make a large batch every weekend and keep it in the fridge.

A cellar with dozens of bottles of canned cold brew does sound pretty cool. I wonder if the flavor would hold up though.

I dump coffee grounds and water in a Mason jar and set it in the fridge. By morning it's brewed and ready to use - just pour through a fine mesh strainer and drink. Less acidity when you do a true cold brew, which is nice.

Lasts in the fridge for a at least a week, so you could brew once a week, strain into other containers, then grab and go for the next several days.

Use hot-tub water from a local hotel as long as you see no sign of algae.

Imagine how nasty a coffee sitting in the fridge for a month would be.

Cold brew in the fridge overnight in mason jars.

Put 2 or 3 inches of water into a large pot.

Add a metal grate or a couple layers of mason jar rings to the bottom of the pot. You don't want your jars of coffee to be in the water.

Bring the water to a boil then turn the heat down so that it's still simmering.

Put your sealed jars of coffee in the pot and close the lid. Leave them in for around 10-20 minutes.

Steam sterilized shelf stable cold brew.

You could also use retort pouches, but that seems like it could be messy.
