I know my brew ratio down to the gram. I weigh my dose, I weigh my water, I time my pours. But for years, there was one number I never bothered to check: my water's PPM, the measure of everything dissolved in it. I told myself it didn't matter that much. Looking back, that was mostly comfortable ignorance, not an actual decision.

I used to believe I was right about my kettle. The temperature felt off, swinging six or seven degrees from where the dial said it should be, and I was convinced something was wrong with the kettle itself. I said so, more than once. I was not trying to trash the brand or make a scene. I was just being honest about what I was seeing.

Two new brewers showed up on my porch while a V60 was already doing the job on my counter. Here's my honest answer to whether most people actually need anything more.

I love dark roast coffee. In a specialty coffee world that treats light roast as the default marker of quality, that puts me a little out of step with a lot of my peers. I've made peace with it, mostly because I didn't arrive at the preference by accident. I got there by roasting the same coffee three different ways and paying attention to what actually happened in the cup.

For years, water temperature was the number I obsessed over more than any other variable in my brewing routine. Two hundred degrees, two hundred and two degrees. I would hover over my kettle treating that two degree gap like it was the line between a great cup and a wasted bag of beans, while my pour and my grind, the two things that probably mattered more, got a fraction of that attention. I have a scale, a kettle, a handful of brewers, different papers for different situations, a grinder, a melodrip, even a refractometer. All of that gear exists in the name of tasting flavor in coffee. But somewhere along the way I stopped asking what all of it was actually for.

Most coffee content ranks equipment. Better kettle here, sharper grinder there, a brewer that solves a problem you may not have. I get why that framing is everywhere. Gear is easy to photograph and easy to compare. But after years behind a roaster and a bar, I think the actual skill worth ranking is not what you buy. It is what you notice.

My gooseneck kettle broke, and I replaced it with the exact same one. That decision, plus a second kettle I also own, is where this honest look at whether you actually need one starts.

I called the Mugen Dripper my third favorite Hario V60 and the regular V60 my fourth, then heard myself say it back and had to test whether that ranking actually held up.

There's a coffee in my life I've never decided that I like. Light roast. I've been drinking it for years, I roast it myself, and most mornings I still wouldn't call it my favorite thing.

Here's what I've landed on, and it took me longer than it should have. Not liking a coffee is the clearest seat you'll ever get. When a cup doesn't move me, I can see exactly what it's doing, and that has been worth more to me than any recipe I've picked up.

I'm testing whether the filter itself, not the brewer, is quietly shaping what ends up in your cup. Here's how I'm setting up the experiment to isolate just that one variable.
