One two ounce shot glass brewed in one 16 ounce pint glass, filtered after three minutes. Practical drinking class style of brewing. Mason jars also work, and pour better.

A friend just sent me this link. I gave it a quick scan, looks interesting

I must be a connoisseur since that's closer to the brew ratio I already use...

But why are there two charts?

i like the mojo.. i hate the mojo.. probably going to be the proud (annoyed) owner of one sooner than later..scott rao makes it sound so easy..HAHA.. though I do appreciate both his books and his passion for consistent cups in a commercial setting. No matter how many gizmos necessary.

Its a refractometer, for analyzing TDS(total dissolved solids) percentages in coffee extractions...
there is an explanation, in the Scott link...quite a ways down..
i don't know about the first chart but the second one is the SCAA chart.

I was setting up a portion control grinder and brewer this weekend and really wished I had the ExtractMojo. One can only have some many cups of coffee in a row before it all tastes the same, so the closer we start to where we end up, the better. Also considering the controlled portions cost about $2 roasted each, it's prudent to be dialed in faster.

The SCAA says that the target for brewing is 75 mg per liter total dissolved solids. I know this doesn't help much, but it is a much better way to measure the result. After all, steeping time and temperature effect the result.

What's a good amount of coffee to use for a standard 12-cup drip machine? I'm taking coffee to a friends and I need to brew a good pot without experimentation.

For my 10 cupper I use between 2 and 2.3 oz depending on grind size. For a 12C if your friends like real coffee and with a medium grind I'd go for 2.5 oz.

Allen, Thanks. I can't assume they'll have a kitchen scale. What's that in tablespoons?

I'm seeing around 5.9 grams/tbsp

2.5 oz x 28.34 gr = 70.85 gr.

70.85 gr / 5.9 = 12 tbsp

Hope this helps

Dan, I'm curious how the coffee came out with the ratio suggested by allenb. I use about double that and the chart suggests exactly double. Granted I'm using a vacuum pot when I brew in volume, and it's only 8 cups, so 16 Tablespoons of coffee is what I use roughly, I weigh it and use 11-12 grams per cup actually.
Anyway, I know it was months ago, but was it successful?

allenb, I don't mean to offend you at all, I'm less experienced than you and I'm just asking mainly to see if I'm wasting half my coffee supply. Shock
Dan
If memory serves, I used 2/3 cup grounds for a standard 12 cup drip machine. The strength was a tad light for me and a little strong for a few people, but most liked it.

Good to know, I will try it with a little less then, no need to be wasting any excess.

This is always an interesting conversation.

that said sure you ca always use the "suggested" amount of coffee and if you are using Fogers or some garbage like that it will always taste the same

but as a home roaster, with the variety of beans you will most likely have at any given time, the suggested amount is not always the best.

this still always boils down to "your persona taste"

and the type of bean you are using...

I strongly suggest you vary up or down to see where it works best for you.

you can break down those ratios and brew two cups to test the amount and go from there; you will be surprised at the taste difference from any given bean and amount of coffee used especially as a home roaster.

Interesting. I have a cheap refractometer, they are like twenty bucks now (optical ones) which I use for testing battery acid specific gravity.

Found this table to convert brix to SG:
http://www.winning-homebrew.com/specific-gravity-to-brix.html
...so I guess for pour through I'm aiming for SG of near 1.007? Never used brix as a measurement before, so I'm guessing a brix of 1.5-2.0 is around what most people aim for? Now I gotta try this; will do the normal cuppa joe tomorrow and post the results here (I already know I like mine a bit thin, I use around 2 3/4 cup water to around 30g coffee beans and a straight 16:1 ratio would have closer to 2 cups water to that much coffee)

Does anyone else have SG numbers for their pour through??
walt_in_hawaii
Just measured my morning cup.... can't read it! My refractometer is designed to read near 1.100 to 1.400 (for battery acid)... I took out a new pipette and drew up a few drops of coffee and put it into the inspection window and the sample registers, but so low in the window its under the scale or graduation marks by quite a bit. Ballparking the reading I get something close to 1.0xx SG but can't be more specific than that. The conversion I did yesterday according to the table says I should be close to 1.007 SG or thereabouts...
