Coffee is not one drink. It is a category. The bean and water are constant across most home brewing, but the method changes which compounds end up in your cup. Two cups from the same bag can deliver very different chemistry depending on how they were brewed.
Four compounds matter for health. Caffeine drives the stimulant effect. Chlorogenic acids are the main polyphenols in coffee and carry most of its antioxidant activity. Diterpenes, specifically cafestol and kahweol, are oils that suppress the liver enzyme responsible for converting cholesterol into bile acids. When that enzyme slows, less cholesterol gets cleared and LDL goes up. Bitter phenolics accumulate with long extractions.
What the method controls. Angeloni et al. (Food Res Int 2020) compared eight brewing methods using the same beans. Espresso had the highest caffeine and polyphenol concentration per milliliter, three to six times more concentrated than drip or moka. But a shot of espresso is 30 mL. A cup of cold brew is 240 mL. Per cup, cold brew delivers more total caffeine and polyphenols because the serving is roughly eight times larger.
Diterpenes are where brewing method matters most for cardiovascular risk. They are oil-soluble, so a paper filter can physically trap them. Orrje et al. (NMCD 2025) measured these across methods. Paper-filtered drip: about 12 mg/L cafestol. French press and percolator: around 90 mg/L. Boiled coffee: 939 mg/L. Some espresso shots reached 2,447 mg/L, though espresso is highly variable. The paper filter is the key. Methods without one let the oils through.
This is why brewing method affects cholesterol. Jee et al. (Am J Epidemiol 2001) pooled fourteen randomized trials. Unfiltered coffee raised total and LDL cholesterol. Filtered coffee did not. Svatun et al. (Open Heart 2022, N=21,083) confirmed the signal in Norway. Drinking six or more cups of boiled or French press coffee daily was associated with total cholesterol about 9 to 12 mg/dL higher than non-drinkers. Filtered coffee showed only a small effect, mostly in women.
A note on the numbers. The per-cup mg values are estimates from per-mL concentrations times typical serving volumes. The relative ordering across methods is well-supported. Exact amounts depend on dose, grind, temperature, time, and bean. Espresso varies the most.
A note on cold brew. The graphic assumes paper filtration, which most commercial cold brew uses. Home cold brew through metal mesh or cheesecloth retains more oil and more diterpenes. The filter matters as much as the method.
The takeaway. If you want the caffeine and polyphenols without raising LDL, use paper-filtered methods. Espresso gives you concentrated chemistry in a small serving. French press and boiled coffee give you everything including the oils that raise LDL. Coffee is not one drink. The brewing method is the variable.
