Well I got curious about this, especially because when I compared different cans of beans that clearly had different amounts of beans in them, when I looked at the labels, based upon the protein, content, the calorie content, the serving size and the net weight of the cans, they all should’ve had about the same amount of beans in them, and yet visually I could tell they didn’t. So I decided to do a little project and carefully weigh and measure and document how many beans were in four different brands of organic black beans.
I don’t understand how all these companies can claim that that their organic canned black beans have the same number of servings each with the same number of calories and protein when clearly just by looking at them, they don’t. The numbers you see on the little yellow sticky notes are how many ounces each can weighed on my digital scale.
I took each can and poured it into a strainer and rinsed the beans well under running water and then returned the beans to their can and then weighed them again. Here’s what that looked like. The bottom number is the new weight of just the beans. I had thought that when they write "net weight," on the can, that meant the amount of the product minus the liquid, but I guess I was wrong.
But what makes this most interesting is that the can on the right? The S and W can is the only one of these that regularly sells for less than a dollar a can. (At Costco) All the rest tend to be well over a dollar.
