These numbers may be correct for the coffee offered by Mountanos Bros. Coffee Co. but they probably are not necesarily correct in a generic way. Caffeine will vary from farm to farm and plant variety to plant variety.
As a general rule robusta has approximately twice as much caffeine as arabica.

How much caffeine in coffee vs. espresso?
You realize of course that those numbers are totally useless without putting what units in what quantities you mean. Is that 1.37 Grams per ounce? mg. per cup, what size of cup? That could be grains per bagful for all we know. Please find the measurements and add to yor page. It would be greatly appreciated.
RE: How much caffeine in coffee vs. espresso?
You make a good point. I don't have the original source so I can't see what info was in the source. This does kind of make this section less useful for
anything outside of a comparison of varietal vs varietal and as I
stated in the article I'm not really sure how accurate it is even for
that.
how much caffeine in coffee vs. espresso?
I see that the numbers have "%" sign after it,, so does that mean mg. per ml.? I've usually seen it expressed as mg. in a cup, ether 8 oz. or 6 oz.(can you believe this used to be the typical size of a coffee cup, lol.
RE:how much caffeine in coffee vs. espresso?
could be but I don't want to speculate.
It's a percentage,
It's a percentage, percentages don't have units. As caffeine is a solid, the figure would be percentage by weight. ie 1.37% = 1.37g of caffeine per 100g of coffee
