The short version
I write everything on The Tuned Cup. Not “oversee”, not “edit” — write. If a guide here has my name on it, I did the research, checked it against the numbers, and I’d stand behind it at your kitchen counter.
Where the habit started
I started drinking coffee young, and I’ve been experimenting with it ever since. I’ll admit to being a little addicted — to the coffee, and to the tinkering. Over the years that turned into coffee workshops, a lot of beans, and a counter where the gear keeps changing, because I buy it, use it at home and then give it away.
Why a tuner
Because that’s what a bad cup needs. Sour, bitter, weak, flat: each one points a direction, the way a flat or a sharp note does. Once you know the direction, you know which peg to turn — and that’s a far smaller job than buying a new machine.
What “independent” means
No publisher assigns these guides. No brand pays for one, sends a brief, or gets to see a draft. There is no PR list of products to feature this month and no deadline pushing a half-researched piece out of the door.
I have been writing and running my own sites for years, which means the editorial standard here is one I set and one I have to live with. There is nobody above me to blame for a bad recommendation. That is the point of it, and it is also the uncomfortable part.
What research means here
“Researched” gets used loosely enough to mean nothing, so here is exactly what it means on this site. Every guide goes through all four of these before a word gets written:
- The numbers, checkedRatio, water temperature, grind size, brew time and extraction, from the standards the coffee world uses — not copied from a listing or another blog.
- Reviews read at scale, for the complaint that repeatsThe same complaint two hundred times — it clogs, it leaks, it drifts out of calibration — is a design flaw, and that is the thing worth writing down.
- The claim checked against a source that isn’t sellingWhere a question has a real answer — why a finer grind fixes a sour cup, what water temperature does to extraction — it gets checked against coffee science, not against marketing.
- Then the cup decidesResearch tells you what should happen. The cup tells you whether it did. When they disagree, the guide says so.
Researched, then brewed. The sites that only research end up recommending whatever looks best on paper; the ones that only test have used three grinders and compared none. The point of this site is the pair.
What I know, and what I don’t
I know why a finer grind rescues a sour cup and a coarser one tames a bitter one, why water just off the boil beats water straight from the tap, and why a scale changes more cups than a new machine. That is the part this site is built on.
I don’t know medicine. I’m not a doctor or a nutritionist, and I don’t play one. When a question crosses that line — caffeine and your heart, acid and your stomach — the answer on this site is always the same: ask a doctor, not a coffee blog.
The line is simple. Anything about your body goes to a doctor. Everything about the cup — grind, water, ratio, time and gear — I can help with.
How I work
- One change at a time, so you know which one worked
- Every recommendation carries its own flaw, in writing
- No brand has ever paid for a place on this site, and none will
- If I get something wrong and you tell me, I fix the guide and say what changed
Get in touch
I read every message and answer most of them myself. Corrections are especially welcome — an error that stays up is worse than one that gets fixed in public.
