Has anyone come across a brewing ratio chart for coffee?

I just got a 1-6 cup manual drip brewer today and I am wondering how much coffee is ideal per cup for this thing?
I also would like to know what is ideal for other brewing methods out there. I also brew a lot of French press. I am not looking for exact measurements but a somewhat close idea.

This is it: ... 2c5ff0c3a5

Hope it brews a good cup.

Thx espressojr!

I just brewed a large mug (approx 450ml) with about 10g of coffee. Brewed a little quick. Got a very light coffee.. It has 5 bottom brew holes. I am gonna try finer grinds. Not bad for $18 tho. :)

10g might be a bit light on the coffee side of things. For 450ml try moving towards 27g. That should help give you a more flavorful cup!

Try 25 - 30g with that much water and see if you like it better.

Sam and Eric are both on the money.

Generally accepted starting point for drip coffee is 60gm coffee per litre of water, and adjust to taste from there. 10g coffee/450ml water will have made a weak brew.

I think the ratio also holds good for press coffee, but that's about the only coffee making process I never use, so have no personal experience.

Unfortunately I see ratios of coffee:water increase as the end volume decreases. In other words, larger batch's need a lower ratio than single cup brews. Just the other day I was wishing their would be a formula to easily calculate a dose with respect to a given yield. Maybe I'll try to come up with something.

As others have said, 10 g for 450 ml is very low! No wonder it was weak.

As far as your original desire goes, this is probably the best thing that is currently available:
Although not in charts, but using a few of these recipes will help you get a feel for how much coffee per water will make a balanced cup. But again the relation is not linear, at least in my experience, so it usually doesn't work to just divide/multiply a recipe to get the amount you want. I think some methods like immersion methods (french press for example) are much more linear with ratios, but pour-over, not so much.

This Vince Fedele presentation from the 2012 Nordic Barista Cup covers the brewing ration chart pretty well, including the differences between drip and infusion methods.

The slides are available here and the NBC page for this is here.

If your switching between press pot and drip, I recommend checking this out as it explains the increase in coffee required in infusion methods such as press pot to get the same TDS result because the liquid retained in infusion methods is coffee at the same strength as the end result and the liquid retained in drip is water or coffee with a much lower TDS as most of the extracted solids have already been washed away.

When I change the volume of my drip methods (Kalita, Chemex/Kone, etc.) I stick with a 16:1 brew ratio (62.5 grams / liter) and don't notice a change in the resulting beverage (though I'm not measuring TDS).
