Showing the top 50 of the 696 coffee products that carry a comparable calorie figure, ranked by protein per 100 calories. Figures per label, sourced from Open Food Facts and tracker user logs.

What the coffee numbers show

696 of the 788 coffee products carry 20 calories or more per 100g, which is the floor below which protein per 100 calories stops being a real number. Across those the median is 3g of protein per 100 calories. 24 clear 10g of protein per 100 calories — about one in 29, and 10g is the line Keith uses for a food that pays for its calories.

Calories run from 20 to 750 per 100g inside this one group, a 38-fold spread, so “coffee” on its own tells you almost nothing about what a portion costs you.

Own-brand is not the compromise here. The supermarket own-label median is 5.1g of protein per 100 calories across 49 products, against 2.9g for the 647 name-brand ones.

Lidl is the only Irish chain with enough own-label coffee to compare fairly — 39 products at a median of 5.1g per 100 calories. Everywhere else this is a name-brand shelf.

What to actually pick

Most of what is sold as coffee is not a protein food. The 24 that clear 10g per 100 calories sit at the top of the table and are the exceptions, not the rule.

120 of the 696 carry 400 calories or more per 100g — the ones worth weighing rather than eyeballing.

Where this fits

Only one chain carries enough of this own-label to break out separately, so Lidl Coffee is the one sub-page here, next to everything else Lidl sells.

Drinks are the easiest thing in a day to miss, so this pairs with the calories people forget to count.

For one specific product rather than the whole group, the 20,000-product database is searchable on Calories in Ireland, and the same figures are built into the free calorie tracker.

FAQ

How many coffee products are in this database?

We track 788 coffee products across Irish supermarkets and brands. 696 of them carry 20 calories or more per 100g, which is the point below which protein per 100 calories stops being a real number, so those are the ones ranked and averaged here.

What's the most protein-dense coffee product?

The table is sorted highest protein per 100 calories first, so the answer is the top row. The more useful number is that the median for the whole group is 3g per 100 calories and 24 products clear 10g — that tells you whether coffee is worth buying for protein at all, which protein per 100g does not.
