How To Make A Chemex Coffee At Home | 787 Coffee
If you love coffee and want to elevate your home brewing experience, Chemex is an excellent option. This pour-over technique produces a beautiful cup of coffee with clarity and depth of flavor; but it can take some practice to master the art of making a great cup. Here are some tips on how to make a Chemex coffee at home:
Let’s Connect!
Prepare The Equipment:
Before you start brewing, make sure all your equipment is clean and in place — including the Chemex, filter, scale and kettle. Rinse the filter with hot water to remove any paper taste and then fold it into three layers so that it fits snugly into the top of the Chemex carafe.
Weigh Out The Beans:
Since each type of bean has different degrees of acidity, sweetness, body and aroma; the amount of ground coffee used will affect the resulting brew's flavor profile. Start off with weighing out 20-21 grams (around 3 tablespoons) for each 8 oz cup; but feel free to adjust this ratio according to your own personal preference as you get more experienced in using this method!
Boil Water & Bloom Grounds:
Fill up your kettle with good quality filtered water and bring it to a boil before pouring it over your grounds. For best results, use a gooseneck kettle which allows for more precise control over water flow rate during pouring — as this helps evenly saturate all the grounds for optimal extraction! Next, add just enough boiling water over the grounds to wet them completely — then wait for around 30 seconds until they “bloom” (bubbles should form).
Add Remaining Water & Plunge:
Once blooming has occurred, slowly add the rest of boiling water into the Chemex — aiming at center while gradually moving towards edges in order to fully extract all flavors from beans! When finished pouring, give plunger a few stirs (but not too much!); then press down firmly on handle until all liquid has passed through filter — usually takes between 4-6 minutes depending on how strong you like your coffee!
And voila —
There you have it: beautifully brewed Chemex coffee ready to enjoy! Making perfect cups at home may take some time getting used to; but once mastered — this pour-over method will provide a delicious cup everytime!

5 lb Single Origin Coffee Beans — Puerto Rico Supremo, Mexico, or Colombia
The Big Bag is 5 lb of single origin specialty coffee from one place, never blended, roasted to order and shipped free. Choose Puerto Rico Supremo grown on our own farm, or single origin Mexico or Colombia, in whole bean or ground. It's the same coffee we serve in our 34 cafés across New York, New Jersey, Texas, Puerto Rico, Mexico City, and Miami, in a bag built for people who make a lot of coffee.
Why buy a 5 lb bag of coffee
A 5 lb bag makes about 150 to 200 cups. That's a month or more for most households and two to three weeks for an office of ten. Buying coffee in bulk means a better price per pound than 12 oz bags, fewer boxes at your door, and no more running out on a Wednesday morning. Every Big Bag ships free and comes in a resealable zipper bag with a one-way valve, so the beans stay fresh from the first cup to the last.
If you brew for an office, a restaurant, a church, a studio, a fire station, or a house full of coffee drinkers, this is the bag.
Three single origins. You pick.
Single origin means every bean in the bag comes from one farm or one growing region, with full traceability. No blending, no mystery beans. Choose your origin at checkout:
Puerto Rico Supremo — Our flagship. Grown at 3,000 feet on Hacienda Iluminada, our own farm in Maricao, Puerto Rico, and honey-processed for natural sweetness. Smooth medium roast with notes of dark chocolate, buttery caramel, citrus, and honey. Naturally low in acidity, the way Puerto Rican coffee is known for. $38 per pound.
Mexico — Single origin Mexican coffee we source directly from [region] and roast in small batches. [Roast level] with notes of [tasting notes]. A smooth, balanced daily cup that works in any brewer. $__ per pound.
Colombia — Single origin Colombian coffee from [region]. [Roast level] with notes of [tasting notes]. Full-bodied and dependable, the classic choice for offices and drip brewers. $__ per pound.
Why 787 Coffee is different
Less than 1% of coffee shops in the world own a farm. We do. Our Puerto Rican coffee is not imported. We grow it, harvest it, process it, roast it, and serve it ourselves, which is what farm-to-cup means at 787 Coffee. That's the quality that earned us #3 Best Coffee Shop in New York City and #32 in North America on the World's 100 Best Coffee Shops 2026.
Roasted to order. Every bag is roasted in small batches after you order and ships within days. You get a roast date, not a best-by date, and you'll never receive coffee that sat in a warehouse.
Specialty grade. Our coffee is specialty-grade Arabica, the top tier of coffee sold anywhere in the world.
Sustainably sourced. Every bag supports coffee-growing communities in Puerto Rico, Mexico, and Colombia.
When you buy this bag, you plant a coffee tree. Every 5 lb bag funds one new tree at Hacienda Iluminada in Maricao, so your morning coffee is growing the next harvest.
Whole bean or ground
Whole bean stays freshest if you have a grinder. If you don't, we grind to order for your brewer:
Drip — medium grind for automatic drip coffee makers, airpots, and commercial brewers
Espresso — fine grind for espresso machines
French press — coarse grind for French press and cold brew
Not sure? Choose whole bean. It keeps longer, and any grinder will do.

How to store 5 lb of coffee
Keep it in the resealable bag with the zipper closed, away from heat, light, and moisture. Don't refrigerate or freeze it. Coffee is at its best within a month of the roast date, which is why we roast to order instead of stocking shelves.
