-Place your mug on a scale and tare it to zero. -Slide it under spout of Keurig and select your usual cup size. -Return the mug to the scale to see your water ratio.
Measure your coffee
I can get 18 grams of freshly ground coffee into the little basket most Keurig machines come with. That basket then sits in this gray bullet-looking device, and that bullet replaces the black K-Cup holder inside the machine.
(Be careful taking the black K-Cup holder out, it has needles in it. Also, be careful using coffee that was very recently roasted. If you fill it to the brim with fresh coffee, it’s likely to overflow everywhere due to the coffee’s activity)
Finding your ratio
Most K-Cups are sitting at about a 1-25 ratio. You want a 1-20 or 1-15 ratio. That means 1 gram of coffee for every 15 or 20 grams of water.
If you use 18 grams and want a 1-20 ratio, you need to select the cup that gives you 360 grams of water into the mug. If you’re selection gives you less than that, you adjust the amount of coffee accordingly.
You have a 12 ounce mug (336 grams), and your selector gives you 10 ounces, or 280 grams. Using a 1-20 ratio, you’d put 14 grams of freshly ground coffee into the basket. For a 1-15 ratio, you’d use the full 18 grams.
Dial in the Grind
I usually want a bigger cup at a 1-15 ratio. This means having to make two baskets and run two smaller cups through in order to get my desired extraction, with some body and flavor. Use only a course grind and nothing smaller than a paper filter grind. Honestly, one notch coarser than paper filter setting.
Well, there ya go. If you are in a hurry and want something close to a pour-over this is your best way. Especially if you are crunching time in the morning and don’t have time for that other crap. Do you need fresh roasted coffee for your machine? Checkout our offerings and price list.
