Big issue is, your definition of bold != my definition.

I’d recommend 4oz grounds per quart (or liter, close enough), room temp for at least 12 hours (24 is ideal), in a French press because it’s easy & cheap. 4oz should be enough to give you bold flavor without the need to dilute, but try it and add more if you need to.

Never used the mason jar method; if you’ve got something good to filter the grounds with (maybe, cheesecloth?), it’ll work just as well I guess.

I don’t recommend any brewing method that uses a pre-installed bag, filter, hop spider, etc because the grains will compact and you won’t get as good of an extraction.

Now, if you’re brewing it for customers, a French press isn’t a great idea; you’ll want to look into industrial methods used by coffee shops, which probably involve large tanks + special filtration systems.

EDIT: if it’s just for a few people, a large French press style cold brew system like this 1.5L one I use at home or bigger if u can help it, would be useful. Here, I’d recommend about a 2:1 water to coffee ratio, 24 hours in the fridge (for sanitation’s sake). Give it extra time to filter and drain the extra coffee, and then dilute until you feel it’s appropriate. You can probably get 6-7 or so liters (around 2 gallons) from that before it gets too diluted. Do like 5 of these and you might be able to sell it all day.

So, I love coffee. It just has always been a hassle for me. Due to my life style, recent jobs, handling my ADD poorly....I just stopped.

Between waking up at 330 for work, trying to stay up late with family, coffee was something I just put down. I would either leave the coffee grinds in the pot, not have time in the morning, not clean out my french press after cold brewing while rusing out the door. Even on my days off, the dread of cleaning something to make coffee made me dread the though.

Well, I decided a simple set up sounded nice. So, without much research I just decided to order:

A couple bags

https://www.amazon.com/Organic-Cotton-Cold-Brew-Coffee/dp/B019BFGMSS

Two 32oz Mason jars and

Two drinking lids

https://www.amazon.com/County-Line-Kitchen-Leak-Proof-Innovative/dp/B07FB4HHLW



I didn't do any research, and idk if I'm doing a great job. I have tons of questions and hope to do some research on concentrate and how much I should use. That said, it's been simple to clean within a min or less and refill. I woke up late today and had 5 min to get ready for work. I got to leave the house with coffee! For the first time in years, I got a small comfort this morning. Yay!


How's my setup? Been using 1:4 ratio for 16 hours give or take. Mostly I've just added sugar, today's was a bit stronger and I added a cup of skim milk. Amazing.

but one of the two bottles n the fridge currently is 1:2 because I had 3 opened bags of ground coffee I needed to get rid of (I used to work for a coffee company, so I currently have 8 bags if beans that are "out of date" left. My former employees still over me coffee. I hope not to use that too often. I'd like to learn to be a little frugal and perfect a good percentage to cost ratio)


I'm rambling. I'm hoping this sub has some good links or data for me to learn from. I've been so happy with my simple setup so far.

I'm way to excited. Maybe too much caffeine this morning too!

Personally I love this : Cold Brew Coffee Maker - Coffee Gator Brewing Kit with Stainless Steel Measuring Scoop and Collapsible Loading Funnel - BPA-Free Filter and Glass Carafe - Black - 47oz https://www.amazon.com/dp/B01KZEO6HI/ref=cm_sw_r_cp_api_i_cY.3DbT77X7JF

Get a good burr grinder to get a nice course grind.

My favorite coffee is this: Portland Roasting Organic Dark Sumatra Whole Bean Coffee - USDA Certified - Carbon Neutral and Award Winning Roasters, 1 12oz. Bag https://www.amazon.com/dp/B00PJ8HT5W/ref=cm_sw_r_cp_api_i_tZ.3DbAKTD6ZR.


The only thing is with this you'll get some small fine particles that get thru the filter. I just run it thru my hot coffee maker with the top open through the white filter. It works.

The aesthetics look really awesome. I've seen many dutch coffee devices being used in South Korea. Like this one from Amazon

https://www.amazon.com/Yama-Glass-Maker-Straight-Black/dp/B004EBUZ1A/ref=pd_sim_79_6?ie=UTF8&dpID=41tRrVDoWJL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&psc=1&refRID=D620MKJ5734WVNBTRF3Q

Most of them are big (which may be good for displays in coffee shops), and like you said, the openings allow dust and air to enter. I think that's why these dutch coffee tasted so acidic from being oxidized. Have you guys tested if your coffee is less acidic than regular dutch coffee since there's less oxidation?

1. How often do you have to replace filters? And will they be expensive to purchase? (With SS filter, do you never have to buy a new one?)
   
2. Does the unit have any thermo-resistance? Sometimes ice melts too fast in the chamber, or the coffee at the bottom warms up too fast and becomes oxidized (especially in summer). It would be cool if there's some thermal resistance so ice melts slow and the coffee at the bottom stays cool. How do you maintain that "constant temperature" that you mention on the website?
   
3. Will the brewing rate become slower as the filter gets clogged up?
   
   As a Korean, I think one of the biggest up-sell is that it prevents "dust" from entering. Korea is currently suffering "micro dust" problem and they are obsessed with preventing dust in any possible way. The fact that this prevents dust and purifies water, it could be a huge up-sell there.
   
   In the future, do you guys plan on making larger version for commercial use? Like at coffee shops? Will you guys ever export to Korea?
   
   EDIT: Haha, I just realized this was being made in Korea after reading Amazon product page.

I use something like that from Amazon. Here’s an awesome tip for you. Rather than putting the grounds in the strainer, I just add it directly into the mason jar and let it sit over night without inserting the cylinder strainer. Then when it’s done cold brewing, I insert the strainer to filter out the big particles and then put this flip top cap on it to pour over into a separate container while using a nut mesh bag to get the finer particles.

Fliptop cap for mason: Drink, Pour, Store! Wide Mouth Mason Jar Flip Cap Lid by County Line Kitchen with Airtight, Leak-Proof Seal and Innovative Flip Cap (WIDE MOUTH, Blue, 1 Pack) https://www.amazon.com/dp/B0776YQTLS/ref=cm_sw_r_cp_api_i_tV.CDbG70SRQF

Nut bag mesh strainer:
2-PACK Best Nut Milk Bag - Restaurant Commercial Grade by GoNuts - Cheesecloth Strainer Filter For the Best Almond Milk, Cold Brew Coffee, Tea, Juicing, Yogurt, Tofu - BPA-Free Nylon 12"x10" Fine Mesh - Durable Washable Reusable - FREE Recipe E-book https://www.amazon.com/dp/B00WFU80KA/ref=cm_sw_r_cp_api_i_-X.CDbF4N6DW3

That was extremely calming and relaxing. Really painted a good picture. The only thing is (Not your fault), it seems you can only make one at a time with that filter, which is rather disappointing. But the video was wonderful, minimal, and well done. Should be proud!

Edit: After going to the items Amazon page, one customer question includes usability with half gallon mason jars, which they say it works with and will hold enough grinds for. Im sold!

I used these filters plus 150g of coffee + ~6 cups of water per jar - a mix of 8 o'clock coffee and Starbucks. Both were whole bean, various dark bean flavors. I ground them in a regular electric coffee grinder on coarse (maybe I'm just used to doing that for French press), distributed them to their filters, rubber banded them, and stuffed them into 1/2 gallon mason jars. I am looking for larger, wider-mouth jars on amazon ATM because the only difficulty is trying to squeeze the water-laden filters OUT of the jars after brewing is complete. They usually tear, which isn't a huge deal, as I pour all of the coffee out first.

Once done, I'll have 3.5ish jars of cold brew coffee. At 150g, it's just the right strength for me. I usually don't take cream or use ice. I don't know how long these keep in the fridge because I've always drank it all within 2 weeks. I've heard anywhere from 2-4 weeks for shelf life. I may save a bit in a smaller mason jar for a month to test that out.

6 cups of water to 150g water seems to be about the perfect mix after much trial and error.

And yes, there is a definite quality difference between coffees. Mixing 8'oclock and Starbucks is a good taste for me that's not terribly expensive. I'd love to find a nice dark bean as oily and rich as SB but cheaper online - any suggestions?

Nothing glamorous but this brews cold coffee and is easy.

She might want to take an extra step at the end and filter through a paper filter to catch smaller grains. But overall a good easy product to use.

There a lot of more expensive options out on the market, just depends on what you are looking for in a brewer.

Mine is somewhat like this :

Looks almost exactly like this

I got it from a ninja coffee maker but there's a million similar things you can buy separately for not much.

If you're not in USA let me know i can help you find other links but looks like it's available from both Amazon and Wal Mart

I really want to get one, but it just doesn't brew enough for me. I brew 64oz every few days, so the size wouldn't cut it. I've messaged them multiple times suggesting a bigger one, who knows if they'll follow through.

Edit: For the record, here is one of my favorite devices for cold brew. Cheap, and brews 64oz easily!

I brew in this, but you can also use it to filter out sediment. Quick and easy to clean.

Don't have one either but you're definitely paying for a e s t h e t i c with the Blue Bottle one. You can save ten bucks by getting a regular Hario bottle in brown on Amazon. This is the same thing, just blue.

[Baratza Encore] (https://www.amazon.com/Baratza-Encore-Conical-Coffee-Grinder/dp/B007F183LK)

Family members love it and it has lasted for them. I'm doing aeropress as well so this works for me. If you are making your own espresso at home though I've read that you should go with their higher end model.

I have made some changes to my ratio and have improved my methods. I used one of these to filter the large ball jars into smaller ball jars using paper filters. And yes, with one funnel this is tedious and uses a LOT of filters. I now use 1 and 3/4 cups coffee to 64 ounces of water. Have added two more stainless wide mouth funnels. So - next day when the brew is done, I set three small Ball jars with a funnel and paper filter in place. Pour off the entire batch into all 3 jars simultaneously, adding some thick and thin brew to each filter, and just dump the remaining grounds. Go away and let it drip, and then even out the jars to half way up and top off with water. I am now using three paper filters where I use to use 4, 5 and 6, trying to filter sludge by the end. Much quicker, less work, and I will do this forever.

I have [this one] (https://www.amazon.com/gp/product/B00I7JKAQ0/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1) and it has done well for me, I make it strong, and dilute the batch in a 3 liter jug
