The SOUP Method
SOUP is a low-pressure, espresso-style brewing method: you push water through a coffee puck, but ground coarser than espresso so that almost no pressure builds (generally under 1 bar) while flow stays high. A gentle soak wets the bed, then a slow, soft press pulls the shot. The result is an espresso-strength concentrate, thick and syrupy, at espresso-level TDS (~9-11%) and ratios near 1:4, yet clearer and more drinkable than a 9-bar shot: you get foam, but none of the oily crema. It is especially good at the dense ultra-light roasts that choke a real espresso machine. 💥
The name is a playful coinage from the Espresso Aficionados ("espressoaf") Discord, popularized by a community member known as DC (who notes he didn't invent it) and brought to a wide audience by Lance Hedrick. It's commonly backronymed "Spro, Only Un-Pressurized."
#Why It Works
Real espresso forces water through a fine puck at about nine bars. That extracts fast but invites channeling and over-extraction (harsh, bitter, astringent), particularly with hard, light roasts. SOUP inverts the trade: a coarser grind opens the bed so water flows freely at under 1 bar, the soak saturates every particle evenly so nothing channels, and the slow press maximizes even contact without compacting the puck. You reach espresso-level strength through high, even extraction rather than brute pressure, so the cup lands sweet, clear, and vibrant instead of bitter and oily.
| Lever | SOUP setting |
|---|---|
| Pressure | under 1 bar (vs ~9 for espresso) |
| Grind | between pour over and espresso |
| Ratio | 1:2 (dense) → 1:8 (long), 1:4 a great start |
| Water | just off the boil |
| Technique | gentle soak, then a slow, even press |
| Cup | espresso-strength, clear, foam but no oily crema |
#The Recipes
| Recipe | Brewer | Ratio | Temp |
|---|---|---|---|
| AeroPress SOUP Recipe | AeroPress | 1:4 (to taste) | 82°C |
| OXO Rapid Brewer SOUP Recipe | OXO Rapid Brewer | 1:4 (1:2-1:8) | 93-96°C |
Both devices suit SOUP because they make the low-pressure press easy to control. The OXO Rapid Brewer naturally caps the pressure and gives tactile feedback on puck resistance, making it the easiest on-ramp; the AeroPress gets there with a tamped bed and a deliberately slow, gentle plunge. Either way you can drink the shot straight, cut it with milk, or dilute it Americano-style. Strength is set by ratio and grind, just like any recipe.
