HOW TO READ PARAMETER GUIDES
WHAT IS A PARAMETER GUIDE?A parameter guide is a brewing recipe to achieve the optimal level of extraction, and most desirable sensory experience. Each coffee has its own parameters which describe the steps and factors to making a delicious drip, espresso or immersion brew; ideal for intermediate-level coffee enthusiasts who want to refine their skills or graduate from standard brew guides. Our parameter guides are developed by our Roasters and/or Coffee Ambassadors and published approximately two weeks after each coffee is released. Much like a cooking recipe, parameter guides are a starting point to steer you in the right direction. You may find the need to make small adjustments to dial in each coffee to your preference. |
PARAMETER GUIDE DEFINITIONS
BREW RATIO: Parts ground coffee or ‘dry dose’ to parts brew water or ‘wet dose’ STRENGTH TDS: Brew strength or ‘body’ measured by Total Dissolved Solids EXT. YIELD: Percentage of solubles (ie. coffee grinds) dissolved during brewing SENSORY DESCRIPTIONS (right): Our Roasters’ explanation of the ideal sensory experience for this coffee. Compare with your own results and make adjustments as needed. |

HOW TO CALCULATE DRIP BREW RATIOBrew ratio lets you follow a recipe for any brew size using a simple calculation: Brew Water (L) x Brew Ratio (g/L) = Dry Dose (g) For example, if you are using the Heritage drip brew ratio of 57.8 g/L and 320g of brew water (as recommended in our pourover recipe), we can calculate the adjusted dry dose as follows: 320g = 0.32 L 0.32 L x 57.8 g/L = 18.5g The adjusted brew ratio for Heritage is 18.5g of ground coffee to 320g of brew water. |

STRENGTH + EXTRACTIONSo you’ve followed the brew ratio and prepared your coffee, now it’s time to taste! Consider the Strength TDS and Extraction Yield targets on your parameter guide so you can make adjustments, or ‘dial in,’ your next brew to get even closer to perfection. |
|
UNDERSTANDING STRENGTH TDSBelow 1.25 % = Light Body 1.25 - 1.35 % = Medium Body Above 1.35% = Heavy Body |
UNDERSTANDING EXTRACTION YIELD18-19% = Light Extraction 19-20% = Moderate Extraction 20-22% = High Extraction |
|
Using the Heritage parameter guide example, your coffee should have a medium body and higher extraction. If your coffee tastes weak, you may need to increase extraction. If your coffee has a heavy body, you may need to decrease brew strength. If your coffee tastes just right, sit back and enjoy!

PARAMETER GUIDE DEFINITIONS
DRY DOSE: Weight of ground coffee WET DOSE: Weight of extracted espresso BREW RATIO: The value that is multiplied by the dry dose to confirm the wet dose DURATION: Total extraction time from start to finish of the espresso shot STRENGTH TDS: Brew strength or ‘body’ measured by Total Dissolved Solids EXT. YIELD: Percentage of solubles (ie. coffee grinds) dissolved during brewing REST PERIOD: Amount of time beans should rest, from the roast date, before brewing SENSORY DESCRIPTIONS (right): Our Roasters’ explanation of the ideal sensory experience for this coffee. Compare with your own results and make adjustments as needed. |

HOW TO CALCULATE ESPRESSO BREW RATIOTo determine brew ratio for espresso we using this simple calculation: Wet Dose (g) ÷ Dry Dose (g) = Brew Ratio For example, if you are using the Heritage espresso brew ratio of 36.5g wet dose and 18g dry dose, we can calculate the brew ratio as follows: 36.5g ÷ 18g = 2.0 brew ratio

STRENGTH + EXTRACTIONNow that you’ve followed the espresso parameters, it’s time to taste! Consider the Strength TDS and Extraction Yield targets on your parameter guide so you can make adjustments, or ‘dial in,’ your next brew to get even closer to perfection. |
|
UNDERSTANDING STRENGTH TDS8-9% = Light Body 9-10% = Medium Body 10-12% = Heavy Body |
UNDERSTANDING EXTRACTION YIELD18-19% = Light Extraction 19-20% = Moderate Extraction 20-22% = High Extraction |
|
Using the Heritage parameter guide example, your coffee should have a medium body and moderate extraction. If your coffee tastes weak, you may need to increase extraction. If your coffee has a heavy body, you may need to decrease brew strength. If your coffee tastes just right, sit back and enjoy!

HOW TO CALCULATE IMMERSION BREW RATIOBrew ratio lets you follow a recipe for any brew size using a simple calculation: Brew Water (L) x Brew Ratio (g/L) = Dry Dose (g) For example, if you are using the Heritage immersion brew ratio of 64 g/L and 248g of brew water (as recommended in our AeroPress recipe), we can calculate the adjusted dry dose as follows: 248g = 0.248 L 0.248 L x 64 g/L = 14.6 g The adjusted brew ratio for Heritage is 14.6g of ground coffee to 248g of brew water. |

|
UNDERSTANDING STRENGTH TDSBelow 1.2% = Light Body 1.2 - 1.3% = Medium Body Above 1.3% = Heavy Body |
UNDERSTANDING EXTRACTION YIELD18-19% = Light Extraction 19-20% = Moderate Extraction 20-22% = High Extraction |
|
Using the Heritage parameter guide example, your coffee should have a light-medium body and moderate extraction. If your coffee tastes bitter, you may need to decrease extraction. If your coffee has a heavy body, you may need to decrease brew strength. If your coffee tastes just right, sit back and enjoy!
