Cold Brew Coffee

[cryhome2mama]

Hey! I was wondering if you could tell us how much you make with one batch. I mean, if you put 4 cups of water in, how many cups of extract do you get out?

Thank you, and i love your 'MacGyvery' solution! lol!

@cryhome2mama

Each batch makes about 21 ounces of concentrate. Yield depends on the size of your cup and the strength of the coffee. I like a my coffee strong and use 1.5 ounces per cup, so I get about 14 cups from 1 lb of coffee.

Is there supposed to be sound or did copyrights take that from you too?

[laughinbob]

@J2daoe

The sound is working. Check the audio control on the video.

This is great video! what's with the dislikes?

[joeypaige]

thanks for the video!

[keepitclean46]

Thanks for this video. I was going to purchase a cold brew coffee maker, but am glad to see there is a way to do it without spending a lot of money.

There most definately is acid in coffee.

Normally brewed coffee is pH 5.5 or so, which is definitely acidic. And If your stomach produced more acid when you ate alkaline substances, Tumms and Alkaseltzer would make stomach problems worse not better.

Also, caffeine is not theobromine.

@BlackHoleSun1988 Thumbs up on this one. Perfect logic. Don't know what the heck the other person is talking about.

You seem like such a nice guy haha!

Poke a pinhole or three in your top jar's lid and turn it upside down into your filter. Then the liquid can trickle slowly out of your top jar through the filter, and into your bottom jar without you having to babysit the whole ordeal.

Thanks. About time to eat those bananas.

I used to have chronic stomach issues. I'd have spells of nausea 4 or 5 times a week. I regularly had to step off the subway to get some air and hope it passed before the next train came, or take a break in the ladies' room in the middle of the morning, hoping I wouldn't get sick at work. Out of curiosity, I started cold brewing coffee in the summer of 2008 and within a week, those symptoms vanished. Now, when I feel sick on the morning train, I know it's only because I'm hungover!

[Hacky2447]

what a complete waste of time.

[MzJaxin]

Thanks for the video! I was thinking of making cold brew and had been looking at cold brewing "systems" -- this is so much cheaper, and easy.

Thanks!

[OpiumKoolaid]

Coffee does not contain acid. If it did, it would taste sour. Coffee, to most people tastes bitter, and that is because of caffeine, (theobromine) which is a "bitter" alkyloid. This alkyloid causes the stomach to produce excess acid, which most people think was in the coffee they drank.

[bc530]

Thanks for sharing that info about coffee.

[spikespeigel]

caffeine is also super soluble in water, so short brew times will yield almost as much as longer brews

[rtrxggg]

@spikespeigel actualy caffeine is barely soluble in water especialy at cold temps at 2.17 g/100 ml (25 °C)

18.0 g/100 ml (80 °C)

67.0 g/100 ml (100 °C)

@OpiumKoolaid when coffee oxidizes it gets acidic making it more bitter wich is why when a barista pulls a shot they try to serve it within 5-10 secconds otherwise it will be too bitter to drink and theobromine isnt caffeine its the active chemical of cocao and is its main alkaloid its name meaning food of the gods in greek

[statesmanls1]

@OpiumKoolaid Thats not true. You try an underextracted lightly roasted espresso shot. Often the first thing you note is how sour it is. If I don't let my machine warm up properly the coffee is sour.

[benjorgensen1]

fresh grind. you will get better flavor complexity. a lot of the flavor in coffee goes away with the gases, and the ground coffee oxidizes very fast, meaning that oxygen is destroying elements in the coffee. i think cold brew is the best way by far!

[OpiumKoolaid]

The coffee is easier on the stomach because cold brewing extracts far less caffeine than hot brewing. It's the caffeine that causes reflux by relaxing the sphinctoral ring between the stomach and esophagus. Be careful with cold brewing...heat also destroys the fungicides and pesticides in coffee beans, and cold brewing does not.

[rhino79]

Wrong. Anyone that has ever actually had cold brew coffee will know it has a very high level of caffeine due to the hours of extraction. It's like liquid crack.

[OpiumKoolaid]

No, YOU'RE wrong. I used to work for a coffee company. If you heated the same quantity of coffee that is cold brewed, you'd end up with enough caffeine to turn your dick inside out. Cold brewing is what they use to remove SOME of the caffeine from coffee beans to make decaf. Hot brewing removes ALL of it. You don't believe me...go do some homework on it, dumbass.

[raparee001]

@OpiumKoolaid Won't adding boiling water to the concentrate destroy the fungicide and pesticide residues?

[OpiumKoolaid]

@raparee001 Some pesticides are heavier than water and might settle and concentrate near the bottom of the cold brew container. Heat will probably destroy pesticide and fungicide residues, but there will be a greater concentration of them in the bottome of the liquid cold concentrate, especially if it's stored a long time. Frequent aggitation of the brew might help keep everything evenly distributed, including heavier flavinoid oils that might settle to the bottom.

[enderswatch]

Great vid! Can't wait to try it!

[LiLtinee]

Interesting process! Thanks for sharing.

[Unityspirit50]

gonna try this... sounds good

[Unityspirit50]

wow does he drink that much coffee a day? LOL

[Unityspirit50]

if you do get acid reflux.. you can use apple cider vinegar with "mothers" and just use like a 1/4 tsp in a tall drink couple times a day.. cures it right up
