Caffeine tastes bitter, but the bitter the coffee taste does not necessarily mean that it contains high amount of caffeine, since bitterness could be related with the previous roasting profile, post harvest process, or even the cultivar of the beans that may contain various amount of caffeine from a type of cultivar to another.
The idea of caffeine contained in a beverage depends on the water-coffee contact time. The longer the water with the coffee ground, the higher the caffeine would be.
This way we can conclude that the espresso would contain the lowest caffeine per serving, on the other hand cold brew coffee would contain the highest caffeine.
Since your question is comparing the Moka pot with drip machines (both brewing method sits between the mentioned above), I would say that brewing with Moka pot would extract more caffeine to the beverage (let’s assume that we use the same amount of coffee grounds with the same amount of water). Brewing with the moka pot will let you boil the water just above the stove that makes higher temperature of extracting water compared to drip machines.
Drip coffee is generally higher in caffeine than espresso type coffee. The longer the grounds are exposed to water, the more caffeine is dissolved.
