A lungo is not a diluted espresso. It is an espresso extracted further - the water keeps moving through the puck, pulling different compounds out over a longer time. The name is Italian for “long.” A standard espresso pulls in 25-30 seconds and yields 25-35ml. A lungo uses the same dose of ground coffee but continues extraction to 35-45 seconds, producing 60-80ml. The extra volume comes from additional water passing through the coffee bed, not from dilution afterward.

​
How is a lungo different from an americano?

This is the most common point of confusion. The two drinks look similar in the cup - both are larger, less concentrated espresso-based drinks. The difference is in the process. A lungo is extracted through the puck. The water travels through the ground coffee for the full duration of the shot, dissolving soluble compounds progressively over 35-45 seconds. A lungo is a single continuous extraction. An americano is a separate process: pull a regular espresso shot, then add hot water to the cup to expand the volume. The espresso is already done; the water is added after. The practical difference is flavour. Longer extraction through the coffee bed pulls more bitter, astringent compounds that would not appear in a shorter pull. A lungo has a distinctly different flavour profile from a diluted espresso - more bitter at the finish, with less of the concentrated sweetness you get from a properly timed shot. An americano, by contrast, can preserve more of the espresso character by diluting after extraction stops.

​
When does a lungo make sense?

A lungo suits drinkers who want more volume from an espresso machine without adding water to the cup. If you are used to filter coffee and find espresso too small but americanos too thin, a lungo sits in between. The extraction style also produces a flavour profile closer to filter coffee - more extracted, more complex in the bitter and aromatic register - from an espresso machine. Some roasters use longer ratios deliberately for lighter roasts that benefit from more extraction. The lungo is not ideal for milk drinks. The additional bitterness from the longer pull can clash with milk rather than complement it, and the volume is already higher than a standard espresso base.

Does caffeine removal change how a lungo extracts?

No. The extraction physics are unchanged by how the caffeine was removed. Swiss Water® Process removes caffeine by soaking green beans in Green Coffee Extract - a water-based solution - which draws out caffeine through osmotic pressure while leaving most flavour compounds intact. The roasted bean structure is the same. Ground particle size, tamping pressure, water temperature, and time all behave identically. When you pull a lungo with Swiss Water® Process decaf, the water moves through the puck on the same timeline, and the compounds dissolve in the same sequence - first acids, then sugars, then bitter components. The extraction curve is not altered by caffeine removal. Residual caffeine in a Swiss Water® Process cup is 2-15mg, compared to 60-150mg in a regular espresso. The lungo format does not significantly raise that figure because the residual caffeine is distributed across the extracted yield, not concentrated by shorter extraction.

Which Colipse Decaf Coffee product makes the best lungo?

Decaf Espresso Beans from Colipse are processed using Swiss Water® Process - solvent-free, 99.9% caffeine removal, 2-15mg residual per cup. The beans are roasted for espresso, which means they are calibrated to handle the pressure and temperature of machine extraction. A lungo extends that extraction, so the roast development matters. A bean with good sweetness and body at standard espresso ratios will carry those qualities into the lungo range before bitterness dominates. Swiss Water® Process preserves the origin character through the decaffeination step, so you are working with the full flavour potential of the bean when you dial in your lungo ratio.
