Ratio and Measuring Water Brew ratio is determined BEFORE the
brewing process. It's the ratio of dry coffee to brew water,
where brew water is the water you are about to use to make your
coffee. Think of it as a recipe, amount of water, amount of
coffee - brew - in the end you get produced coffee. The term
itself can refer to either ratio of coffee to water, or water to
coffee. Usually if it's coffee to water, it's expressed in
percentage, so 62.5grams per 1000g of brew water is is 62.5/1000
or 0.0625 or 6.25% - all the same thing. The inverse produces a
number in the 15's to 17's depending on who recommends what
ratio (water to coffee). Some people also call this brew ratio,
or coffee brewing formula, it's all the same thing, just the
inverse. In the example above, 1000g/62.5g is 16.0 The concept
comes from the brewing control charts - an example of which can
be found multiple places on the internet. They express the brew
ratio in wacky mixed units
