The cold brewing process does not release as much acidity from the coffee grounds as hot brewing, which makes it a great soft drink. I think there is also less caffeine in the brew.

Thanks for reminding me of something I've gotten away from for a long time.

Hi John
I hadn't thought of it for passages. Good tip . Sometimes conditions are such that only instant coffee is made and this would be infinitely better. Unlike hot coffee, it apparently does not deteriorate if kept for several days.

Regarding the caffeine content, it may be higher than when hot brewed:
https://driftaway.coffee/coldbrew/
Wikipedia states the opposite though:
https://en.m.wikipedia.org/wiki/Cold_brew_coffee
It must depend greatly on the amount of coffee used and the immersion time.

From the same site as above, a bit about the history is interesting. The first record of this method was in Japan in the 1600's:

Re: Cold brewed coffee

love me some cold brew. You can also heat it up and serve like normal coffee if you swing that way

Re: Cold brewed coffee

We have been in an intermittently rolly anchorage the last few days, so filtering the cold brew was not practical. It drips slowly using filter paper, and the risk of coffee flung all over the place was not appealing .

Instead of filtering, I simply carefully strained the cold brew using a fine tea strainer, stopping as soon as significant sediment from the bottom of the jar started coming through. I let that settle half an hour or so, decanted again, leaving the tiny amount of sediment undisturbed, and then refrigerated that bottle.

Dead easy, no mess, no fuss and indiscernible from the carefully filtered brew.

This will become my standard method .

PS I have discovered that iced coffee late in the afternoon is even better with caramel chocolate .

Re: Cold brewed coffee

I've been letting it sit in the sun all day and then soak overnight it seems to be just as strong as when I brew it but it doesn't make me as jittery and it seems to have a smoother taste. I don't drink coffee everyday, just when I need a little extra energy so I plan on making some and keeping it in the fridge.

See the Toddy coffee maker. Makes the cold brew process a little easier.

dunno about letting it get sunlight / warmth? I was always advised to put it in the fridge (cold+dark) before and after. Either way, the end product is the proof

On board at the moment day time temps are 30+, dropping to 24-26 overnight, so my cold brew is not very cold .

Personally, I would add warm water if you want the flavour to be extracted a bit better rather than leaving it in the sun. Sunlight tends to deteriotate flavour.

We are continuing to enjoy our cold brew tremendously as iced coffee every afternoon. It is a real treat after a swim .

Re: Cold brewed coffee

We fresh grind (whole beans keep stay fresh longer in our experience, so we can pack our favorites from home) then steep 2-3" of grounds in a French press overnight (cold water). Makes a strong concentrate that dilutes to 2 quarts of bold yet smooth coffee. The French press makes pouring/filtering/spilling a non-issue

Unlike hot brewed, cold brew will keep up to a week in the fridge without affecting taste.

It's not a replacement for a fresh hot cup in cool weather, but in warm weather our regular coffee pot gets put into deep storage.

Cold coffee with a dash of sugar and some RumChata is an excellent afternoon cool down beverage

Fwiw you can do the same with tea to make iced tea, but it doesn't keep as long as hot brewed iced tea - 2 to 3 days max.

Re: Cold brewed coffee

Thanks for the feedback everyone. it's taking me awhile to get back because like I said I don't drink coffee everyday. but I'm doing a test, I put equal amounts of coffee and water into same size jars I put one in the Sun and one just on the counter out of the Sun. tomorrow I'll do a taste test.

Re: Cold brewed coffee

Down Heah, we call this Sun Tea, doesn't sound right for coffee though?

Re: Cold brewed coffee

I'm very surprised. I totally expected the solar coffee to be stronger but I honestly can't tell the difference.

Re: Cold brewed coffee

We discovered cold brew by accident when we unexpectedly ran out of LP about 15 years ago - haven't ever went back. The best part is you brew it, and it is instantly available without the hassle of brewing fresh.

We currently use a large tea maker and we have a mortar and pestle, bash the beans up into french press consistently then toss it in with water and let it sit overnight - then into the cool box it goes. The tea maker has a built in tea leaf strainer that keeps the large particles out of the cup.

Interesting. The mix must be pretty accommodating as long as it is not super hot. I keep mine in a cupboard for 24 hours, but room temp gets to about 30 C at the moment. I strain and chill it after 24 hours and we drink it with coffee icecubes after our dive in the afternoon, so I am not keeping it long.

In winter, I think it will be back to hot cups of aeropress. Without a microwave, heating it would be a lit of a pain for me. Just as easy to boil the kettle. We'll see. I love the smell of coffee and although the flavour is very good cold, I miss the aroma.

Do you refrigerate it without straining it? I once kept it unstrained for 48 hours, and it was probably my imagination, but it did not taste as smooth.

Re: Cold brewed coffee

You may be right about it becoming more robust? But we never drink ours that slowly

Re: Cold brewed coffee

if they're crushing by hand, grains could be quite large, so brewing takes longer
