A cold brew notebook, sources attached.
An independent site about making cold brew at home. Ratios come from the makers' own instructions, research from the published papers, and gear specs from manufacturer pages.
The numbers were already out there
Most cold brew advice stops at “steep it 12 to 24 hours and use a coarse grind.” Maker manuals publish their own recipes, and food scientists have measured what steep time, grind and temperature do to the cup. Those numbers sit in PDFs and journal tables. This site collects them, checks them against each other, and turns them into settings you can brew with.
I ♥ Cold Brew is published under its own name. When a page says “we”, that's who it means.
Nothing here is hands-on tested yet
Gear guides are built from published specs and carry a Research roundup label, with no scores or ratings. When a guide is tested, its label changes to Tested with the date, and the measurements go up as a Lab file with the raw data.
How a product makes the list
- It was in stock when we checked.
- Its specs come from the manufacturer's page, or a retailer's when the brand's site can't be read, and each one is dated when we check it. A spec the brand doesn't publish shows as a dash. We don't fill gaps with guesses.
- Every pick says who it's for, why it's on the list, and what it costs you to own: cleanup, batch size, fridge space, filters, or a grinder you'll also need.
- Prices aren't listed. They change too often to keep right, so the link goes to the current one.
- Commission never puts a product on a list. It can decide which store we link to: a brand's own program over Amazon when both carry it.
Some links pay us
If you buy through one of them, the store pays us a commission and you pay the same price. The disclosure page explains which links and how they work.
