Is there a word for Energizingness?

I need a single word that means the "degree by which something is energizing". In a sentence:

On a scale of 1 to 10, how would you rate the _______ of this coffee?

This percentage represents the energy drink's perceived _______.

This should apply to any such food, like energy drinks/bars, candy, etc.

But it seems Energizingness is not an English word. Is there a word for this?

Solution 1:

Are we forgetting how we

rate the potency of this coffee?

the power of something to influence or make an impression.

stimulation resulting in an energizing effect on the person and/or his/her body and mind would be the impression or influence the substance in question has. This seems most appropriate of a word for what is essentially a drug. It is a clinical term as well as in my impression, pop culture lingo.

In short, potency packs the most oomph for a single word to describe what your trying to say without "izingness"ing us up yet another dictionary word.

• edit: also potency is appropriate when we are actually objectively asking someone about the coffee, the individual asked would then default to which aspect of the coffee is important and most apparent to them to answer as to the flavors effect or its neurological impact or both.

Solution 2:

You could simply reformulate the sentence

On a scale of 1 to 10, how energising would you rate this coffee?`

Solution 3:

In the context of coffee, I'd probably use Strength, which is generally understood to correspond to how "awake" the coffee makes you feel.

Solution 4:

On a scale of 1 to 10, how would you rate the efficacy of this coffee?

Efficacy is a somewhat more technical term, style-wise. I would recommend strength in the specific case of a poll about coffee, as monoRed suggested. But "efficacy" might be more appropriate in other cases. It's more general than "energizingness", and shorter than "effectiveness". As mentioned in another comment, "potency" is also roughly synonymous with "efficacy" here.
