Adon Palss asked:


I’ve looked up caffeine extraction here and other places and oftentimes it involves harsh chemicals or laboratory equipment. Yet I see all sorts of things like water and doughnuts with artifically added caffeine.

I’m actually starting to get into winemaking and would really like to know if there’s a way to extract caffeine from one source like coffee or tea, to then add it to other safe consumables.

Or barring that, is it legal to produce or buy straight caffeine crystals anywhere that are fit for consumption? There must be, it seems like the entire soft drink industry relies on it.

Is there a way for me to make coffee so it has more caffeine? I need to do my homework tonight (it’s due tommorow), but I’m very sleepy. Is there anyway to make my coffee with more caffeine? Or tea? I need anything to keep me awake throughout the night.

I have to do a science experiment for school, and was wondering is it possible to extract caffeine from drinks such as coffee, tea and energy drinks.

Coffee, tea, or — sunscreen? Research into the effects of caffeine in mice shows the drug can help get rid of sun damaged skin cells before they become cancerous.
