Brew the best Coffee-Roast Dates (AGAIN!)

Roast Dates Are a Lazy Proxy for Quality

Roast dates for coffee drive me nuts. Not because information is bad but because this particular data point has been wildly overvalued. A roast date gives you something while pretending to give you everything. It’s insufficient. It’s boring. It’s a line in the sand that people cling to because it’s simple, not because it’s meaningful.

Roasting coffee is a violent act. Hundreds of chemical compounds are disrupted, rearranged, and fractured in a matter of minutes. Post-roast, the coffee is actively off-gassing CO₂, which resists water, and slowly reorganizing itself into something stable and expressive. To reduce all of that complexity to a single date stamped on a bag is absurd. It’s like judging a human being by their birth certificate alone and we've gone down that road.

When we roast coffee, we don’t rely on a single marker. We take color readings. We measure TDS and Brix. We cup. We brew. We brew it multiple ways. We drink it black. We drink it with milk and sugar or honey.  We pull shots.  We ask how it behaves, how it evolves, whether we’re proud of it, and whether it deserves to be released. Do we have room.  Will it sell.! Roast date is just one small piece of a much larger conversation.

I was in Oslo a month ago and visited Tim Wendelboe (of course, right?) The experience was good, solid, thoughtful, well executed. Not life-changing, but meaningful. Patricia and I sat there thinking we're actually doing this and pretty dang well. Anyway, they had a Kenyan coffee on the retail shelf, roasted the previous Friday. It was Monday. I asked if they’d brew it for me. They refused. “Too fresh,” they said.

I (sorta) respect that. Truly. It shows some discipline and intention.

But here’s where things get interesting.

In our Big Shoulders world, we routinely begin to cup coffee within an hour of it coming out of the roaster. Not because it’s ready, but because we’re trying to understand potential. Cupping has always been an incomplete process over-romanticized even, but it’s an indicator. A snapshot, not a finished portrait.  Just like roast dates.

This morning, weeks later, I brewed that same Wendelboe Kenyan coffee at home. Clever dripper. 18:1 ratio. Short contact time. A brew approach that mirrors how I’ve seen it handled in cafes like theirs. And it was delicious. Still lively. Some brightness, but softened. The acidity had settled into something more integrated. The fruit was clearer, calmer. More like slowly stewed peaches.  It was closer to my idea of what coffee should taste like, 4 weeks off-roast.  To some that's a coffee that should be dismissed because it's "old."

This is what roast dates don’t tell you.

Coffee changes. It evolves. It opens up. There is real value in allowing coffee to age sometimes significantly before declaring it ready or good.  We want water and coffee to interact, not brush past each other. Not a one-night stand. A committed relationship over two, three, four minutes of contact time.

Or, in espresso, those intense twenty-five seconds where everything matters...  I guess that is a one night stand in the coffee world. 

A roast date doesn’t tell you how the coffee behaves with water.
It doesn’t tell you how it drinks with milk.
It doesn’t tell you whether the coffee has settled into itself or is still fighting for identity.

It just tells you when heat was applied.

Roast dates aren’t useless but they’re not the truth. They’re a starting point, not a verdict. Great coffee isn’t about freshness alone. It’s about readiness. And readiness is something you can only discover by brewing, tasting, waiting, and paying attention.

Coffee deserves more curiosity than a stamp on a bag.
