1:14.4. Same grind as the Hario V60 even with the single drain hole.

Brew process

Bloom 0:00

Start the timer and pour just enough to wet the whole bed — about twice the dose — then leave it while the grounds give off their gas.
Pour 0:45

Add the rest in slow circles, keeping the water on the coffee rather than the paper.
Drawdown

Let it finish, then lid it. The Rambler holds the heat, so the only thing left to get wrong is leaving the brewer sitting on top of it.

These numbers were written for a Medium-dark roast. That is what the temperature and the time below assume — it is a setting, not a fact.

Dogspeed Flat Track Coffee Medium-dark · Latin America, varied seasonally — typically Colombia Supremo, Guatemala (Huehuetenango or Marilandia) and Brazil (Vila Boa natural) The one I use
Andino Leal Merit Coffee Medium · Huila, Colombia, from a committed group of small-scale producers
Tractor Beam Superthing Coffee Medium · Blend, roughly half washed Colombia with washed and natural Ethiopia; components rotate seasonally

If your bag is lighter or darker than that

18 g to 260 g is about 1:14. Everything below is relative to this recipe's own numbers.

Temperature: Go hotter. A lighter roast is denser and gives up less at the same temperature — take it to the top of the range, or just off the boil.
Time: Give it longer. Another fifteen to thirty seconds of contact, whether that is a slower pour or a longer steep.
Grind: Grind finer, one step. Light roasts under-extract before they over-extract, and sour is the failure you will meet first.
Dose: Leave the dose alone at first. If it is still thin after the other three, add a gram or two.

Temperature: Go cooler. A dark roast is brittle and gives up everything it has immediately — back off five degrees or let the kettle stand a minute.
Time: Cut it short. Stop the brew at the first sign of it slowing down; the last of the drawdown is where the ash comes from.
Grind: Grind coarser, one step. Bitter and hollow is the failure you will meet first, and coarser is the fix.
Dose: You can use slightly less and lose nothing. A dark roast tastes stronger than it is.

Temperature: The temperature on this recipe is written for exactly this roast. Start there.
Time: The time is the time. Change it only after you have tasted it once as written.
Grind: Grind is still the one thing worth moving. Everything else in the recipe is fixed so that it can be.
Dose: The dose below is what these numbers were dialed at.
