I didn’t know that the caffeine output read lower in espresso and aeropress than cafetierre – why is that?
Caffeine relates two tyhings
1)how much water passes through...
If you look at non chemical decaf for example its basically run water through.
Lower temps / less water = more coffee flavour for the amount of caffeine (bitter taste)
2/ The bean variety (Robusta vs Arabica or a mix)
that should probably be 1st ....
Robusta grows easily... doesn't need shade .. and has more caffeine (insecticide) .. Arabica only grows in specific circumstances under trees... making it far more expensive to harvest as well.
How are espresso machines in the UK not espresso machines?
They are designed/tuned to froth milk... its mostly one or the other (basically set too hot for espresso...lots of steam to froth milk or condense water for expresso.

Not really though. The cheaper thermoblock ones generally have two heat settings, one for espresso, and one for steaming milk. You do need to wait between them for it to warm up/cool down.
HX/DB machines are fairly well set up for both.

Glad I bought my sage duo temp then 😘

off topic, but just a quick note to say that my Lelit Mara (HX) is excellent at this - you can set it to espresso or steaming priority, and at 3 temp (range) settings for whatever bean you are using. It has 2 PIDs: one on the boiler, and one on the grouphead thermosyphon outlet. It basically holds the grouphead at a consistent temp, but then cranks up the boiler temp for short periods for extra steam when it thinks you need it (ie: after pulling a shot). Works well
