I'm not going to argue with you because it looks like you are sure about it
But just a quick reminder, espresso is one of the brews that's has less caffeine
Caffeine is delivered only after 19" of contact with water, a normal espresso is Brewed in 25"
If you want for whatever reason stay low on caffeine don't have drip, french press or mocha
The best options would be espresso and aeropress for you ☕🫂💜
