The season changed. The cup had to change with it. Here’s what I found on the other side.
There’s a particular stubbornness that comes with being a coffee purist. For years, I held the position that real coffee was hot coffee — that drinking it cold was a concession to trend, a compromise of the ritual, something you did when you didn’t really care about the cup itself.
I held that position through four summers. Then July arrived this year and the air in my city decided it was done being reasonable, and I made a cold brew for the first time, and I had to sit down and have an honest conversation with myself about how wrong I’d been.
This is that conversation, written out.
What changed this summer
Cold brew isn’t new. But what’s happening with it in 2026 is different from the cold brew of previous years.
Cold coffee continues to lead beverage sales this summer, heavily dominating afternoon dayparts — and the reason isn’t just the heat. It’s that cold brew has evolved from a simple alternative to hot coffee into its own category, with its own language of flavour and texture and experience that has nothing to do with “iced hot coffee” and everything to do with what happens when you let time do the work instead of heat.
The cold brew I make now isn’t a consolation. It’s a choice.
What cold brew actually is — and what it isn’t
Let me be clear about this because it matters for the flavour conversation.
Cold brew is made by steeping coarsely ground coffee in cold water for anywhere from 12 to 24 hours. No heat is involved at any stage. The extraction is slow, patient, and completely different from what happens when hot water hits ground coffee.
What this does to the flavour is significant. Without heat, the compounds that make coffee bitter and acidic — the ones that develop rapidly in a hot extraction — don’t dissolve the same way. The result is a cup that’s smoother, sweeter-tasting without added sugar, and with a different flavour profile than the same beans brewed hot. Not better. Not worse. Different in a way that’s worth understanding on its own terms.
The first time I tasted a well-made cold brew and actually paid attention to what I was tasting — really paid attention — I found something I wasn’t expecting: depth. Not the bright, acidic, top-note clarity of a good pour-over. Something lower and rounder and more settled. Like the difference between a conversation that moves fast and one that takes its time.
I liked it more than I expected to. That’s the honest truth.
The versions worth knowing
Not all cold brew is the same, and this is where it gets interesting.
The classic is simply cold brew over ice — concentrate diluted with cold water or milk to your preference, served in a glass that has enough ice to keep it cold without turning it to mush before you’ve finished it. Simple, clean, and better than most things you’ll have in the afternoon heat of a July day.
Nitro cold brew is the one that looks like a Guinness — cold brew pushed through a nitrogen tap that gives it a thick, creamy head and a slightly sweet mouthfeel that comes entirely from the nitrogen, not from any added sugar or milk. Nitro cold brew is pushed through a canister with nitrous oxide, which yields a delicious cup of cold coffee topped with an ultra-smooth, frothy foam head. The first time you watch it pour you’ll understand immediately why it became a café obsession.
Cold brew tonic is the one that surprised me most — cold brew concentrate poured over tonic water with ice. The bitterness of the tonic and the sweetness of the cold brew do something unexpected together: they lift each other, create a brightness that neither has alone. It’s a summer afternoon drink that tastes nothing like anything else in the café world.
How I make mine at home now
It took three attempts to get right, and I want to tell you what I learned from the wrong ones.
The first attempt: too fine a grind. Fine-ground coffee in a cold brew produces a murky, slightly bitter result — the particles over-extract during the long steep, and you lose the clean quality that makes cold brew worth making. Go coarser than you think you need to.
The second attempt: not long enough. Eight hours produces something thin and underdeveloped. Sixteen to eighteen hours is where the magic lives — long enough for the oils and flavour compounds to fully extract, not so long that you start pulling unpleasant notes.
The third attempt: everything right except the ratio. Too much water, too little coffee, and the result is pleasant but flat. One part coffee to eight parts water for a standard strength. One to four if you’re making concentrate that you’ll dilute later.
The fourth attempt — which is now just “making cold brew” rather than “attempting cold brew” — came out exactly right. I kept it in a sealed jar in the fridge for four days and it was excellent every morning. Which is the other thing nobody tells you about cold brew: it keeps. Unlike hot coffee, which starts dying the moment it’s made, cold brew in the fridge holds its quality for up to two weeks. One Sunday afternoon of preparation, two weeks of excellent mornings.
That arithmetic won me over completely.
What it does to the café experience
Here’s the thing I noticed when I started ordering cold brew at cafés rather than making my usual request for filter coffee: it changed how I experienced the afternoon entirely.
The hot cup is a morning thing for me — the ritual, the warming, the deliberate slowness of it. The cold brew is something different. It’s a 3pm thing, an afternoon thing, a thing that says: the day isn’t over yet and I’m not ready for it to be.
There’s an energy to it that’s different from the energy of a hot espresso. Not sharper or stronger — actually calmer, more sustained, without the spike and drop that a quickly consumed hot coffee can produce. The specialty drinks shift means cafés are competing more with premium desserts than daily morning routines — and the cold brew, done well, sits comfortably in that territory. It’s a treat. It’s something to sit with on a warm afternoon and feel like the choice to stop and have something excellent was the right call.
My honest position, revised
Hot coffee is still the cup I love most. The South Indian filter on a cool morning, the pour-over on a weekend with nowhere to be — those are mine and they’re not going anywhere.
But cold brew has earned its own place. Not as a compromise of the ritual — as an extension of it. A different kind of presence for a different kind of time of day. And in a July that has been genuinely, aggressively hot, the cold brew has made me a better-humoured person in the afternoons, which is not nothing.
I was wrong for four summers. I’m glad I stopped being wrong.
Are you a cold brew convert or are you holding the line on hot coffee year-round? And if you have a cold brew ratio or recipe that changed everything for you, I want to know what it is. Tell me in the comments.
