Field notes
Decaf coffee, explained.
A practical guide to the process, the roast, and choosing your next cup.
FIELD NOTE 01
What decaf is
Decaf is coffee that has had most of its caffeine removed, usually while the beans are still green, before roasting. After that, it's roasted, ground, and brewed like any other coffee.
FIELD NOTE 02
How caffeine is removed
Removing caffeine is only half the job. Both Coff coffees use water-based decaffeination, according to our roasting partner. These methods aim to draw caffeine from green coffee while preserving as much of its aroma and flavor character as possible.
That is why process matters to us: decaf should still have body, a clear roast identity, and a reason to take another sip. Paper Sun uses the Swiss Water Process; Blue Arcade is described as water-process decaf. We name each method only as specifically as our supplier does.
FIELD NOTE 03
Two coffees. Two characters.

FIELD NOTE 04
Keep your ritual
Whole bean lets you grind for the brewer you use, from drip to French press. Adjust your grind and brew recipe to suit your cup.
FIELD NOTE 05
How to choose your decaf coffee
Start with roast and the kind of cup you enjoy. Paper Sun is our medium-roast Peruvian decaf; Blue Arcade is our dark-roast option. Both come as 12 oz whole bean. Compare the roast, origin, and process details above, then visit the product pages for current availability.
A decaffeination method is one useful detail, but it does not describe the entire cup. Origin, roasting, grinding, and brewing all play a part in the coffee experience.
FIELD NOTE 06
Brewing your first bag of decaf
Begin with the recipe you already use for your brewer. Grind close to brewing, measure your coffee and water, and change one variable at a time. If the cup is not where you want it, adjust the grind or strength and compare the next brew.
Keep a short note of the coffee, grind setting, recipe, and what you tasted. That is more useful for finding your daily cup than expecting every decaf to behave the same way.
