When is it best to grind the coffee?
It is best to grind your coffee just before brewing.  As soon as you grind the coffee it begins the aging process and oxidizes.  At Rx Coffee we will grind the coffee for you.  Please ensure you select the correct grind for your brewing method of choice.

"Dialing it in"?
In the coffee world the phrase "dialing it in" is used to describe the perfect cup of coffee.  To "dial it in" we must understand how to get the perfect extraction of coffee by way of coffee-to-water ratio, grind size, brew time, and water temperature.

Coffee-to-Water Ratio?
For pour over coffee the optimal water to coffee ratio is usually between 15-17 to 1.  Meaning for every 1 gram of coffee you should use between 15 grams to 17 grams of water.  If you're having a hard time converting just keep in mind 1 gram is equal to 1 millileter (ml).  We suggest using a 13-14 to 1 ratio for using a french press.  

We understand most people don't geek out on coffee as much as we do, so use these ratios as general rule.  Depending on the brewing methodology and personal tastes the coffee-to-water ratio will vary.

Grind Size?
This will vary depending on the brewing method of choice.  For an explanation of grind sizes and suggested brewing methodology please see the photos below.
