What are the differences in the coffee made from a moka pot vs. a pour-over? Does one extract more of the beans' oil than another?
2 Answers
Pourover methods tend to use a paper filter which prevents oils from flowing into the coffee. Pourover is also brewed at a low pressure and a higher coffee to water ratio, giving the coffee a gentler, tealike taste. Moka pots are closer to espresso in terms of intensity and pressure, and does have more body and a richer flavour. I personally prefer pourover coffee but everyone has their own tastes.
Mokas extract oils (fatty acids) better than pour-over or filter coffee methods, which are the poorest. French presses do the best at fatty acid, presumably due to the grains being submersed so water-oil separation has more time to occur.
According to
- Alexia N. Gloess et al., “Comparison of Nine Common Coffee Extraction Methods: Instrumental and Sensory Analysis,” European Food Research and Technology 236, no. 4 (April 1, 2013): 607–27, DOI: 10.1007/s00217-013-1917-x, §9 Extraction Efficiency, p. 618,
a French press (Bo) by far has the best "Fatty Acids per g R&G" extraction efficiency, with the Bialetti moka pot coming in a distant second place {plot (b) below}:

Answers should be written in your own words, text from other sources should support your answer, not make up the majority of the answer. Copied text must be both attributed and marked as such. Linking to your own space without denoting it as such is undisclosed affiliation and not permitted either (and frankly totally unnecessary in this case).– Stephie ♦Commented Jan 16, 2022 at 19:19

How do fatty acids relate to oil? Are fatty acids the same as oil? Are all fatty acids in the bean oily? Are all oils in coffee beans fatty acids? And how does the pour over figure into this? It seems filter coffee has no fatty oil extraction. Is that because they only used a paper filter? Though this source seems to be relevant, I'd reiterate Stephie's comment that you have to actually answer the question.– JJJ ♦Commented Jan 19, 2022 at 5:02

I understand that the source you're citing only published the figures in bulk, but in your answer it's quite confusing as it seems you're only using that one plot. Perhaps removing the picture and citing the relevant numbers in a table would be easier?– JJJ ♦Commented Jan 19, 2022 at 5:02
