How to Make the Middle Child

What you need

• Espresso machine
• Portafilter
• Grinder capable of drip-to-espresso range
• Paper filter sized for portafilter basket
• Pour-over or drip paper filter (for second-pass filtration)
• Scale
• Tamper
• Serving cup or vessel
• Small spray bottle (for static reduction)
• Funnel (optional, helps load coffee into basket)
• Cocktail tin (optional, for iced variation)

Method

1. Dose 20 g of coffee and mist the grounds lightly with water to reduce static buildup before grinding or transferring.

   20 g is typically the maximum capacity of a standard portafilter basket; fill to whatever your basket allows.

2. Grind the coffee to a setting between drip and espresso — noticeably coarser than a typical espresso grind.

   On an EK43-style grinder calibrated to chirp at zero, start in the 11:00 to 12:00 range and adjust based on flow rate in the machine.

   Expert tipThe coarse grind prevents pressure from building the way it does with espresso; water disperses through the puck rapidly, acting more like a shower head than a pressurized extraction.

3. Place a paper filter at the bottom of the portafilter basket and pre-wet it thoroughly before adding coffee.

   Pre-wetting seats the filter and removes any papery taste before the brew begins.

4. Load the ground coffee into the lined portafilter — use a small funnel if available for a cleaner transfer — then rest a tamper lightly on top to level the coffee bed.

   Do not apply a full espresso tamp. The goal is only to level the surface, not to compress the puck.

5. Lock the portafilter into the espresso machine and brew, stopping at a yield of 180 g.

   At this coarser grind, water flows rapidly. Expect the full yield in roughly 30 to 40 seconds, though flow rate varies by machine.

6. Immediately pour the brewed coffee through a second paper filter — a V60 or any pour-over filter — into your serving cup.

   This double-filter step is critical for flavor clarity. The rapid brew and coarser grind allow fine coffee particles to pass through the portafilter filter; the second pass catches them.

   Expert tipFlavor clarity is the central challenge of this method. Skipping the second filter leaves a muddier, less defined cup profile.

7. Serve the approximately 6 oz result as the base Middle Child, or choose a variation: stir in about 4 oz of hot water for a longer, drip-style coffee shot, or add about 4 oz of ice to a cocktail tin with the hot coffee, shake, and pour over fresh ice for a by-the-cup iced coffee.

   The base drink brews at a 1:9 ratio, placing it in strength between drip coffee and espresso — closer to a long black.

Why this works

Brewing at a drip-range grind on an espresso machine removes the pressure buildup that defines espresso, so water disperses through the puck evenly and rapidly rather than forcing a concentrated extraction. The paper filter at the base of the portafilter catches most solids immediately, and a second pour-over filter pass removes the fine particles that sneak through during this fast, coarser extraction. Together, these two filtration stages deliver the flavor clarity of a slow pour-over at a fraction of the time. The espresso machine contributes consistent temperature control and even water distribution that manual pour-over technique struggles to replicate at cafe pace.

Where beginners go wrong

1. 1

   Cup is cloudy or muddy with visible sediment

   Do not skip the second filter pass. Running the output through a V60 or any pour-over filter removes the fine coffee solids that pass through the portafilter filter during the rapid, coarser-grind extraction.

2. 2

   Water flows too slowly or pressure builds like an espresso shot

   The grind is too fine. Open it up toward the drip end of the range and re-dial until water flows through at a rapid, even rate without significant pressure resistance.

3. 3

   Cup tastes weak or falls short of the intended strength

   Confirm you are stopping at no more than 180 g out from 20 g in (a 1:9 ratio). If you are consistently overshooting the yield, stop the machine earlier or evaluate whether the grind is too coarse and flowing too freely.

4. 4

   Coffee grounds are difficult to load cleanly into the lined portafilter

   Use a small funnel to guide the grounds into the basket after the pre-wet paper filter is in place — it keeps the process tidy and prevents grounds from landing outside the basket.

What you should taste

Clean and well-defined, with a strength that sits between drip coffee and espresso. The double filtration removes fines and produces a clear cup without sediment or muddiness. Adding bypass water softens the profile toward a classic pour-over character; shaking over ice produces a bright, refreshing iced coffee.
