Subject: Chemex Brewing Time - Please help
 

My morning routine is to freshly burr grind 12 tablespoons of coffee and brew it with 36 ounces of water to produce coffee for my wife and me.
My question is how long this should take.
My brew time is about 8-10 minutes and this seems crazy long.
I am grinding on the courser side of the dial and my grind looks courser than what I see in online videos
Is the chemex just not suited for > one cup production?

thanks for any help

Holy Moley!
12 tablespoons (14.3 grams per tablespoon) = 171.6 grams!!!!!!!!!
Surely, you don't mean TEASPOONS?
If you don't, you're grinding 4x's (and more) the amount of coffee needed for 36oz in a Chemex. You're at about a liter of water, so about 45-48 grams would be correct. Don't grind coarse for Chemex. If you're using the standard "3 ply" filter, a medium drip grind would good for starters.

1 cup? In what world? 36 oz is 7 cups (plus 1 oz) by normal cup standards (5oz cups), not 8 oz mug size.

You are really mixed up here.

36oz water, 48 grams coffee counting the 30 seconds to wet the grounds to allow the "bloom" should take around 3-4 minutes tops.

Thanks for the reply
I assure you that I am not mistaken
The standard ratio (and one I confirmed on this site just yesterday) is 2 tablespoons of ground coffee for every six ounces of water
Therefore, 6x2 tablespoons is 12 tablespoons for 6 x 6 ounces of water = 36
this is to make 6 cups of coffee
Normal standard measures,again for many years, is 6 ounces per cup

but I am trying to understand, using the standard 3 ply chemex filter why my brew of 36 ounces of water takes > 5-6 minutes to get thru the filter

thanks - any advice on brew time would be welcome

Mark

I do chemex every day. Video from Intelligentsia says around 50 grams (can't remember exact amount) for 25 0zs water. Chemex own site says one rounded tablespoon of coffee per cup. They also say you can use more to your taste.

As the Old Perfesser (Casey Stengel) used to say to sportswriters "You could look it up."

If that amount is associated with too slow a brew time I guess the coffee needs a coarser grind.

Cheers, Skylar

Starbucks recommends 2 tablespoons per 6 ounces water. I think 3rd wave coffee is too weak. The ratios below are too weak.

I can only assume your confusion arises from the use of tablespoons to measure coffee. Starbucks equates 2 tablespoons to 10 grams
i.e 10 grams to 6fl.oz
25/6 x 10 = 41.7 grams
So Intelligentsia is recommending MORE coffee than Starbucks at 50 grams.

I have had a lot of success with the following method for Chemex: Grind medium to medium-coarse. Pour as much water through as you can for the desired contact time (3:30-4:00 for 36 oz would probably be a good starting point), let the filter drain, discard it, and pour the rest of the water directly in. Obviously you can dial in grind and contact time however you like using this procedure.

I worked for SBUX, and now I work in a third wave shop. I assure you that neither party recommends using so much coffee. You are misunderstanding properly extracted for weak. It is a misconception that just throwing more coffee in will make the coffee "stronger." If you use too much coffee and not enough water, the coffee will just not be fully extracted. If you use the correct amount of coffee, and still feel that the resulting brew is too weak, then grind a bit finer, maybe add a gram, slow your water flow. By adding more and more coffee, you're just going to lose all of the flavor of the back end and end up with really over-powered, underextracted cups.

There are a couple of issues here. First, you haven't noted the grinder you are using. I have a feeling that your grinder is creating too many fines, and thus hindering the flow. Are you using a quality burr grinder? That might be one of your major issues. Second, having a cheap scale that reads to .1g would make this a lot easier to diagnose. Yes, 2tbsp:6oz of water is a ratio that is cited over and over, but the issue is that every coffee has a different weight, so that ratio is inherently flawed.

I'm enjoying a Chemex of Olympia's Kanzu right now that I made with 40g of coffee and 640g of water (Heart's ratios), and I can assure that it is anything but weak.

Mark, the recommended brewing time for a Chemex of that volume is about 3:30-4min, as cited previously. If grinding coarse isn't bringing you any lower than 2x that, you're either using WAY too much coffee, or your grinder is insufficient. It can also be the speed at which you're pouring, but you stated that it takes 5-6 min to drain, which pretty much rules out the water flow being the issue.

Hope it helped.

Seems like you might benefit from a scale - you can pick up a gram scale pretty cheaply.  I have come to rely very much on weighing my coffee.  Start out with 60 grams per liter of water and see how you like it.
