The no-plunge technique that produces a cleaner, brighter french press cup. Exact ratio, timing, and step-by-step instructions.
Quick answer
Hoffmann's ratio is approximately 1:16.67 — that is 30g of medium-ground coffee per 500ml of water. Pour all the water, wait 4 minutes, break and skim the crust, wait 5 more minutes, then pour gently without plunging. Total time: ~10 minutes. The result is a dramatically cleaner cup than the traditional method.
| Press size | Water | Coffee (g) | Coffee (tbsp) | Serves |
|---|---|---|---|---|
| 3-cup / 12oz | 350 ml | 21 g | 4 tbsp | 1 mug |
| 4-cup / 17oz | 500 ml | 30 g | 6 tbsp | 1-2 mugs |
| 8-cup / 34oz | 1000 ml | 60 g | 11 tbsp | 3 mugs |
| 12-cup / 51oz | 1500 ml | 90 g | 17 tbsp | 4-5 mugs |
All measurements at 1:16.67 ratio (60g per liter). Medium grind — finer than traditional french press.
1. Grind and dose (medium grind). Hoffmann uses a finer grind than the traditional coarse french press setting. Think medium — closer to drip than to sea salt. Weigh your dose: 30g per 500ml of water. If you don't have a scale, 6 level tablespoons is close for a 17oz press.
2. Pour all the water and wait 4 minutes. Boil your kettle, pour directly onto the grounds, and start a timer. Don't stir. Don't touch it. A crust of coffee grounds will form on the surface — that's normal. The crust actually insulates the brew, keeping the temperature stable during the steep.
3. At 4 minutes: break the crust and skim. Take two spoons. Gently push the crust of floating grounds toward the back of the press, then scoop them off and discard. You don't need to get every last particle — just remove the bulk of the floating material. This step removes the grounds that would continue extracting and contributing bitterness if left in contact with the liquid.
4. Wait 5 more minutes. After skimming, set the press aside for another 5 minutes. During this time, the fine particles suspended in the liquid settle to the bottom of the press under gravity. Patience here is what produces the clean cup — the longer you wait, the more sediment drops out of suspension.
5. Pour gently, don't plunge. Place the plunger on top just to act as a strainer, but don't push it down into the liquid. Pour slowly and stop before you reach the bottom — the last centimeter or so is concentrated sediment. Pouring through the mesh without plunging keeps the settled fines undisturbed.
Traditional french press uses 1:12 — a heavy dose designed for a 4-minute steep with coarse grounds. Hoffmann's 1:16.67 seems dramatically lighter, but the extraction efficiency is much higher. Three things compensate for the lower dose.
First, the finer grind. Medium grounds have more surface area than coarse, exposing more coffee to the water. Each gram extracts more. Second, the longer total contact time — 9+ minutes versus 4. Even though extraction slows as the liquid saturates, the extra time pulls significantly more dissolved solids from each particle. Third, no agitation. The undisturbed brew extracts more evenly than a stirred or plunged one, where turbulence creates extraction inconsistencies.
The net result is a cup with similar dissolved-solids concentration to a traditional 1:12 brew, but with a different flavor profile — less muddy body, more clarity in the high notes, and a cleaner finish. If you find Hoffmann's ratio too light, increase to 1:15 (33g per 500ml). Going tighter than 1:14 with this method tends to over-extract during the long steep.
The practical difference comes down to what you want in the cup. The traditional 1:12 method — coarse grind, 4-minute steep, full plunge — produces a heavy, oil-rich, full-bodied cup with noticeable sediment. Some people love that thickness and don't mind the grit at the bottom. It is fast, forgiving, and produces reliably bold coffee.
The Hoffmann method trades speed for refinement. The 10-minute process produces a cup that tastes more like a well-made pour over than a typical french press — clean body, brighter acidity, no silt coating your tongue. The flavor complexity is noticeably higher because the even, gentle extraction develops more nuanced notes than the aggressive traditional method.
Neither method is objectively better. If you drink dark roasts with milk and sugar, the traditional method's bold intensity holds up better. If you drink light or medium roasts black and want to taste origin characteristics, the Hoffmann method reveals them more clearly. Try both with the same beans and decide which cup you prefer.
A 10-minute brew in a single-wall glass press like the Bodum Chambord will lose significant heat. By the time you pour, the coffee may be lukewarm — especially in colder kitchens. Two solutions: preheat the glass thoroughly (fill with boiling water, wait 30 seconds, dump), or use a double-walled press that retains heat throughout the extended steep.
Stainless steel and double-walled presses were practically made for this method. They hold temperature within a few degrees over the full 10 minutes, ensuring consistent extraction from start to finish. If you own a thin glass press and find Hoffmann's method produces weak or sour coffee, heat loss during the long steep is the most likely culprit.

Coming soon
Hoffmann uses approximately 1:16.67 — that is 30 grams of coffee per 500ml of water, or 60 grams per liter. This is lighter than the traditional 1:12 french press ratio because the longer steep time (5+ minutes) and undisturbed extraction pull more flavor from each gram of coffee.
