Roasted here, not imported
Every bag is roasted on our 1972 Probat in Chelsea and stamped with the roast date. Nothing sits in a warehouse for a season before it reaches you.
Small-batch roastery · Chelsea, New York
Coffee roasted for people who are changing their routine.
Harborlight Coffee Works roasts clean, low-bitterness arabica in 12 kg batches and blends it with green coffee bean extract, Ceylon cinnamon and chicory root — a black cup that tastes good enough to replace the 400-calorie one you used to buy on the way to work.

Why people order twice
A roastery, not a supplement company
We are coffee people first. Everything we add to a bag has to earn its place on flavour, and everything we claim has to be something we can put in writing. That is the whole business model.
Three ingredients, printed in full
Arabica coffee, green coffee bean extract and one botanical — cinnamon, chicory or cacao. No sweeteners, no anti-caking agents, no proprietary blends hiding behind a trademark.
Honest about what coffee does
Black coffee is a near-zero-calorie drink that many people use to replace sweetened lattes. That is a real, measurable swap. We do not promise pounds lost — we promise a cup worth switching to.
Checkout you can trust
256-bit TLS on every page, PCI-compliant card processing, and card data that never touches our servers. Order confirmations arrive within two minutes.
Caffeine you can plan around
Each product page lists caffeine per 8 oz cup, so you know exactly what you are drinking at 7 a.m. and what you should not be drinking at 7 p.m.
30 days to change your mind
Open the bag, brew it, and if it is not for you, email Kaycee and we refund the order. We would rather lose a sale than keep an unhappy customer.
Inside the roastery
Twelve kilos at a time, twice a week
Our roaster holds 12 kg of green coffee. That is small — deliberately. It means Kaycee Smith can taste every batch against the reference cup from the week before, and pull anything that drifts.
Green coffee arrives from three importers we have used since 2014: a washed Colombian from Huila, a natural Brazilian from Cerrado Mineiro, and a seasonal Ethiopian lot. We cup samples blind before we buy, and we buy for one season at a time so nothing goes stale in the hopper.
Roast profiles are logged in a spreadsheet that goes back to 2018 — bean temperature every thirty seconds, first crack, development ratio, drop weight. If you ever want to know exactly how the bag in your kitchen was roasted, email us the roast date and we will send you the curve.

How ordering works
From our drum to your kettle in four steps
1
Pick a roast or start with the sampler
Every product page lists origin, roast level, caffeine per cup and full ingredients. If you are new, the sampler is the cheapest way to find your cup.
2
Choose whole bean or a grind
Tell us your brewer — French press, drip, pour-over, moka, espresso, or cold brew — and we grind on a Mahlkonig to match. Whole bean stays fresher if you own a grinder.
3
We roast, rest and ship
Orders placed before Monday or Thursday noon ET go onto that week's roast. Beans rest 24 hours, then ship USPS Priority or UPS Ground with tracking.
4
Brew, and tell us how it went
A brew card ships in every box. If the cup is off, reply to your order email — we will fix the grind, swap the roast, or refund it within 30 days.

“I switched my 8 a.m. flat white for Harbor Light black and honestly did not miss it after week two. It is the first coffee I have had that is not bitter without milk.”

Straight answers
Questions we get before the first order
Will this coffee make me lose weight?
No coffee will do that on its own, and we will not tell you otherwise. Black coffee is around 2 calories a cup, so replacing a sweetened café drink with it removes calories from your day. Any result comes from that swap and the rest of your routine, not from a bean.
What exactly is in the bag?
Roasted arabica coffee, green coffee bean extract, and one botanical depending on the blend — Ceylon cinnamon, roasted chicory root, or crushed cacao nibs. Full ingredient lists are printed on every bag and on every product page.
How fresh is it when it arrives?
We roast Tuesdays and Fridays and ship within 24 hours. Most domestic orders arrive 5 to 9 days after the roast date, which is inside the ideal window for drip and pour-over.
Do you ship outside the United States?
Currently we ship to all 50 US states and to Canada. International shipping outside North America is not available yet; email us and we will let you know when it opens.
Can I talk to a person?
Yes. Call 631-621-7985 Monday to Friday, 9:00 to 18:00 ET, or email services@weightlosscoffeeworks.com. Messages are answered by Kaycee Smith or by Renata on our support desk.
Not sure which roast suits your morning?
Tell us how you brew and what you drink now. Kaycee answers every message personally, usually the same business day.
