How it compares
Iron per portion, next to other foods on the drinks shelf.
What holds it back
Polyphenols
Tannins and other polyphenols bind plant iron in the gut.
Morck TA, Lynch SR, Cook JD (1983), Am J Clin Nutr. Coffee with a meal cut iron absorption from 5.9% to 1.6%. An hour before the meal it made no difference; an hour after, it blocked as much as with the meal.

About 0 mg per 100 g, so 1 cup (200 g) gives about 0 mg. The number is from USDA FoodData Central: Beverages, coffee, brewed, prepared with tap water.
Does coffee block iron absorption?
Its polyphenols bind plant iron in the gut. Heme iron from meat and fish is barely touched. Keep it away from your plant-iron meals.

Iron is from food tables, for the food as eaten, and real foods vary with the cut, the brand and the recipe. Your body takes in a share of it, and a larger share when your stores are low.
