Having fallen out of favor somewhere between the advent of the capsule and the reign of the strong espresso, filter coffee has since unfairly suffered from a bad reputation. That of a lukewarm, bland liquid, coming from a plastic coffee maker forgotten on a sideboard. We're starting to get used to the grimaces at the mere mention of "filter coffee" (yes, really, we assure you).
The influence of trends has led us to dismiss filter coffee in favor of the sacred espresso, but at Celsius, we're betting on its gradual return to French homes, in addition to espresso, and here's why:
Aromatic Complexity: Filter as a Terroir Revealer

Espresso is a concentrate: high pressure, short extraction, dense result. What makes it strong is also its limitation: the finest, most volatile aromas often disappear into the syrupy beverage.
Filter coffee works in reverse. Water slowly passes through the grounds, at low pressure, over a longer period. It carries along aromatic compounds that espresso is less able to reveal: floral notes, fruity acidity, subtle sweetness. It's extraction by persuasion rather than by force.

Caffeine: Espresso vs. Filter
This is one of the most ingrained misconceptions: espresso "wakes you up" more than filter coffee. The reality is more nuanced; although more concentrated in caffeine, the average volume of espresso consumed provides less caffeine to the body in the morning. Here's the proof in numbers:
| Minimum Caffeine Content | Maximum Caffeine Content | Average Amount of Coffee Consumed | Minimum Caffeine Intake | Maximum Caffeine Intake | |
| Espresso | 1.33 g/L | 2.50 g/L | 36 mL | 0.048 g | 0.09 g |
| Filter | 0.34 g/L | 0.78 g/L | 240 mL | 0.082 g | 0.18 g |
So you will generally get twice as much caffeine in a filter coffee as in an espresso. It should be noted, however, that these figures can vary greatly if the person preparing the coffee is not precise with the coffee dose in the filter or the fineness of the grind. These indications are relevant when you consume coffee in a coffee shop, for example.
Furthermore, the perceived effect also differs: the caffeine in filter coffee is absorbed more gradually, producing a longer-lasting and less intense alertness. So, if you're looking for a sustained boost, opt for a large cup of filter coffee. Conversely, if you can't tolerate large amounts of caffeine, you can stick to filter coffee in espresso-sized quantities.
Filter Coffee in the Morning
There is sometimes debate within the scientific community about the relevance of drinking coffee first thing in the morning, on an empty stomach. We leave this debate to the experts and let you draw your own conclusions.
In our opinion, whether taken first thing in the morning or a little later as a precaution, filter coffee is ideal. Its acidity is present but not aggressive. Its bitterness is controlled. Its texture is light. It's a coffee that can be drunk in large quantities without the body protesting, and it pairs well with breakfast without overpowering it. You can enjoy your buttered toast with complete peace of mind (and even dip it in the coffee, we promise we won't judge).

Ritual - n.m.
We won't hide it, the little ritual that accompanies certain pour-over methods contributes to their overall appreciation. In complete contrast to espresso, which involves a high extraction speed and coffee swallowed in a few sips, filter coffee is a true ode to slowing down.
There's a sense of fulfillment in preparing your V60 in the morning: the sun is rising, there's no rush, you're feeling good, Tintin (are we going too far?).
Filter Coffee Price - n.m.
A final, and not least important, argument is that the equipment needed for pour-over methods is generally more accessible than for espresso. Usually, all you need is a kettle, a grinder, and your coffee maker (which can be a simple ceramic element).
- An Origami Dripper in ceramic: €25 to €40
- A good quality manual conical burr grinder: €50 to €100
- A basic kettle, with or without temperature control (see our article on water): €20 to €40
- Abaca paper filters (100 units): €8
- A carafe for serving: €25 to €40
That being said, as with any passion, you tend to upgrade your equipment as your knowledge grows: a precise kettle that controls temperature to the degree, a scale to precisely control the dose, a better grinder, and a host of more or less expensive accessories.
Furthermore, when you drink filter coffee, you generally consume much less coffee, for several reasons: preparation time, the amount of hot beverage consumed, and the higher caffeine content. Count 12g of coffee for the morning, which usually keeps you going all morning, versus an unlimited number of 8g espressos, depending on the person.
NB: A clarification is needed. The term "filter coffee" is convenient but misleading: all so-called pour-over methods actually include a filter, whether it's made of paper, metal, or cloth. What we oppose to espresso is more of a philosophy of extraction: slow, open, without pressure. We will therefore use "filter coffee" and "pour-over methods" interchangeably in this article.
