How We Research

Updated on

Every guide on Single Serve Coffee Deals starts with one question: will this coffee maker suit the person who is shopping for it? For us, that means how many people you brew for, whether you use pods or grounds, and how much cleanup you'll put up with.

Here is how we answer it.

1. We start with how you brew

A single cup on a weekday morning and a full carafe for guests need different machines. A compact pod brewer is the wrong tool for a table of eight.

We check the brew type, the cup sizes, the reservoir and the carafe. When your habits limit the choice, we say what to look for.

2. We compare specs and features

We look at whether a machine takes pods, grounds or both, the brew sizes it offers, the reservoir or carafe size, timers, auto shut-off and what comes in the box.

Keurig, Ninja, Cuisinart, Hamilton Beach and BUNN describe their machines in their own words, so we name the brand for every claim. We also note the warranty terms the maker lists.

3. We look at buyer feedback

We read through what buyers report after using a machine. We look for patterns, like slow brewing, leaks, weak coffee, hard cleanup and parts that wear out.

One angry review doesn't sink a product. A pattern does.

4. We score each product

Our score weighs specs, features and buyer feedback against what you're shopping for. A machine that's great for one reader may score lower in a guide written for another.

Scores spread out on purpose. A 10 is rare.

5. We keep pages up to date

Products change, and some disappear from stores. Makers sell similar models and bundles under close names, so we check each model number and what comes in the box, and we only link new units.

We skip unknown brands with no track record and any machine with a known recall. When we update a guide, the "Updated on" date at the top changes with it.

What our picks are not

Our picks are research, not lab tests. We don't claim to have used every machine we cover.

Coffee makers heat water to near boiling, and steam and hot water can burn. We don't call any machine safe, and we label maker claims as the maker's claims.
