# How to Brew: Cold Brew! (Cold Brew 101)

Coffee/Water Simplified Equation:

Not really an equation, rather some simple math to get you where you need to go! A reminder that you will need a scale that has a grams settings for certain.

-Take the 1:1 Coffee to Water rule (1gram coffee to 1milliliter water), and apply the brewing recipe ratio to it.

-So if you have a 1:5 brewing ratio, and had 340g of Coffee, you would need 1700ml of Water (340 x 5 = 1700). Do it this way if you already know your brewing vessel's volume capacity.

-If you don't know the vessel's volume capacity, put it on a scale and tare it. Then add water until it is close to full to find a unit to go by.

-If you have a vessel that has the ability to hold 2500ml of Water, and the brew ratio is still 1:5, then you would need 500g of Coffee (2500 / 5 = 500).

-This can be applied in every which way of brewing with coffee, so have fun for now and we will visit this again in further detail later!
