Two people waiting for coffee can make a small dripper feel unnecessarily complicated. One mug fills first, the other gets the last thin trickle, and neither person knows whether there was enough coffee in the basket. Use a server and treat the brew as one batch. For two modest cups, start with 30g of coffee and 500g of brewing water, then divide the finished drink between them.
That is a starting recipe, not a promise of two full 250ml mugs. Some water stays in the grounds and filter. If your usual mugs hold 300ml each, a 500g water recipe will leave room at the top. Before changing the coffee, fill your mugs with drinking water to the level you normally enjoy and weigh that amount. This small measurement prevents a surprising number of brewing arguments.
Set out the whole brew before boiling the kettle
You need a dripper and matching papers, a server that comfortably holds the finished batch, scales, a timer and enough hot water for brewing plus rinsing. Check the dripper’s stated capacity. A larger batch should never require you to fill a small cone to its rim. A stable server matters more than matching glassware; do not perch the dripper on a narrow or uneven vessel.
Hario’s own V60 guide uses 15g coffee and 250ml water for one serving and suggests doubling both for two. It also recommends a server for the larger batch. Keep that ratio while you learn how your particular beans and grinder behave. A different ratio from a favourite roaster can work well too, but changing recipes every morning makes progress difficult to judge.
Rinse the paper, discard the rinse water and add the grounds. Level the bed with a gentle shake. Place everything on the scales and reset them before pouring. Keep a cloth nearby for drips, with the scale display clear of the kettle’s spout. The timer is there to record what happened, not to rush you through a hot-water routine.
Pour in stages without chasing a perfect stopwatch reading
Wet all the grounds first, using just enough water to reach the dry patches. After a short pause, continue with controlled pours until the total reaches 500g. Hario suggests about 30 seconds for the initial wetting and water around 92–96°C. Stay below the paper’s edge and avoid directing a hard jet into one spot. You are trying to make repeatable contact with the coffee, not draw decorative circles.
Record when the water finishes draining. A two-person batch does not necessarily take twice as long as a one-person batch: the depth of the bed and the way you pour have also changed. Treat a large difference from yesterday’s time as useful information. It might point to a grind change, a different paper or a pour that disturbed the grounds more heavily.
Give the server a gentle swirl before serving so each cup receives the same mixture. Alternate a little coffee between the cups if you want to split it evenly without using scales again. Taste after the first sharp heat has eased. Milk drinkers should make their comparison with the usual amount of milk, since that is the drink they actually want to improve.
Change one thing on the next brew
If the cup is thin and the water ran through unusually fast, try a slightly finer grind while holding the dose and water steady. If the bed drains painfully slowly, move a little coarser. Taste is the deciding evidence: a long brew is not automatically bad, and a short one is not automatically good. Keep the changes small enough that you can reverse them.
Write four details on the coffee bag or in a phone note: dose, water, grinder setting and what you tasted. “Pleasant with milk, too light black” is more useful than a string of elaborate tasting notes. After a few batches, your dependable recipe may remain 30g to 500g or move slightly either side. Either result is worthwhile if both cups reach the table together and you would happily make the same coffee tomorrow.
