Costco Greek Yogurt - liars


The greek yogurt that costco has put out, which I feel is inferior to their previous one states on the information panel that it contains 4 cups (about).

It actually contains 3 1/4 cups which is not about 4 cups. What a rip off. Who do I contact abuot this. Costco just wants to give you your money back and get you out.

  1. Yogurt's normally sold by weight. What weight does it say on the label?

      32 oz
      Fage yogurt said about 4 cups and is 35 oz

      1. re: sobon2

        Good grief, one cup is equal to 8 fluid ounces, 32 ounces of yogurt is four cups. Rather than Costco cheating anyone, sounds like someone was cheated by a math teacher.

        1. re: ChinoWayne

          Is yogurt considered fluid? Also, thanks for the insult.(*.*)

          1. re: Cathy

            Thank you Kathy, I am aware hof how many ounces are in a cup but why do they put almost 4 cups when it is not.

            1. re: sobon2

              Dry volume uses a cup measurement. Liquid volume uses weight measurement.

              A gallon jug filled with milk is 8 pounds, fill it with flour and the jug will weigh between 10 and 16 pounds (sifted or packed flour).

              You are mixing fluid volume with dry volume with weight.

              You could fill the gallon jug with lead balls and it will weigh far more than that same jug filled with milk, yet the jug contains 128 volume ounces. Eight pounds of lead balls weighs the same as eight pounds of milk and both are 128 weight ounces.

              1. re: Cathy

                A gallon jug filled with milk is 8 pounds...

                At the risk of sounding nit-picky...a gallon of whole milk weighs 8.6 lbs while a gallon of skim weighs 8.63. Skim weighs more because it contains no fat, which weighs less than water. This is why bulk milk is always sold by weight. That way they can tell if it has been watered down.

                1. re: al b. darned

                  I did not know that. Thank you for the factoid and more evidence of why liquids are measured by weight and not volume.

                  I never paid attention to how much things weighed until I broke both elbows -at the same time. Long story...

                  1. re: Cathy

                    Okay, so if we're allowed to be picky, I think we have the flour volume to weight conversion numbers wrong above. According to this calculator:


                    A gallon (16 cups) of flour would only weigh about four and a half pounds, which makes sense because a cup of flour only weighs between four and five ounces.

                    But this of course only underscores your overall point that weight and volume are two very different things.

      2. OK, this little argument got me curious, so I marched out to the kitchen and looked at the carton. 907g divided by a 227g serving size. By my math, it comes out to 3.9955947 servings. That looks like "about 4" to me.

        1. re: Jeri L

          It does look like 4 but not 4 cups as they state on their information label.

          1. re: sobon2

            For the purposes of weights and measures, the only measurement that matters is the one on the front label that says "NET WT 32 OZ (907g)". Since yogurt is not completely liquid, it is measured by weight and not volume. If you weigh the full tub of yogurt and it's less than that, then there's a problem. The cups shown on the nutrition information (where it says "Serving size: 1 cup (227g); Number of servings: About 4) is only for reference purposes. If you have two pounds of yogurt that is 3 1/4 cups, then you have some very dense yogurt there.

            If you still feel there is an error somewhere, then call Member Service at 1-800-955-2292 or send them a letter to PO Box 34311, Seattle WA 98124. They will likely tell you what we've already told you: Yogurt is measured by weight, not volume.

            1. re: JK Grence the Cosmic Jester

              Thank you for your helpful reply.I will take it up with Costco.

              Point being that I use at least one container per day and was assuming based on their information that I would be ingesting approx. 80gr of protein. Now I find that that is not the case. This can make a difference in peoples lives So it is actually mis-information that they are printing. What about the other information, is it correct or just close?
              Thanks for the number and address..

              1. re: sobon2

                So you are going to tell Costco the net weight is not 32 ounces?

                If you are eating 1/4of the container a day, you are getting the nutrition described. If you are measuring one cup a day, then for three days you are getting more than what is described on the label and the last day will get less.

                In any case, you are not reading the complete explanations posted here.

                1. re: sobon2

                  If it is a health issue to track the protein you are eating, just invest in a cheap digital food scale. I buy the big containers of Fage yogurt and portion it out into a reusable container I bring to work. I just weigh out 227 grams, which is approximately one cup, and I can look at the package and know exactly how many grams of protein, fat, etc. I am ingesting by the accurate weight measurement.

                  1. re: sobon2

                    As long as the nutrition label makes reference to a WEIGHT-BASED SERVING that is about 1/4 the weight of the container, then it IS CORRECT that 4x the nutrition label is the nutrition value for the entire container and you have no problem.

                    The container is sold by weight, so the volume doesn't come into play for that. There is no shortage unless it's short by weight.

                    I believe you'll find that nowhere on the container does it say the container has 4 cups. It says that a serving is 1 cup/227g (by reading of above) and thus there are about 4 of those in a container. But since we're dealing in weight as the ultimate measure, the cups are actually the approximation.

                    If the nutrition panel made no mention of weight, I think you might have a point in that 3.25 cups is quite a bit short of the approximation of 1 cup x "about 4". But given that there is apparently a weight-based serving on the container, you don't have a problem. Eat the whole container and you have about 4 of those weight-based servings.

                    Perhaps that spells it out a little more clearly than some of the other posts? Perhaps not. ;-) There certainly can be confusion in nutrition labeling, it's far from ideal, but I don't think there's a big deficiency in this case. The reality is that everything should be done in weight and we should all have a scale because volume measures are subject to significant variance from a lot of factors.

                    1. re: CrazyOne

                      Thank you very much.
                      Part of my confusion was that FAGE yogurt is 35.3 oz(1000g) and reads serving size 1 cup / servings per container About 4
                      I'm sticking with FAGE.

                    2. re: sobon2

                      I checked out the package yesterday at the store. You are absolutely getting 80 grams of protein per container calculated at their 227g serving size. You are totally missing the math here.

                      1. re: ferret

                        The nutrition panel says the serving size is 227 grams?

                        1. re: Robert Lauriston

                          It (and all the 32 and 64 ounce yogurt containers I have in my refrigerator right now) state "Serving Size: 1 Cup (227g)"

                          1. re: Cathy

                            227 grams is eight ounces. If one cup weighs eight ounces, and there were only 3.25 cups in the tub, then it was short six ounces by weight.

                            1. re: Robert Lauriston

                              Container states "32 ounces (907g)". 227gx4= 908g. Hence "about 4" servings.

                              Liquids are measured by weight and not volume. Hence, 227g is about the one cup measure of 8 ounces and not the one cup measure of a measuring cup.

                              Liquids are measured by weight, not volume. 8 ounces of yogurt does not look the same in a measuring cup as 8 ounces of corn syrup or 8 ounces of water. This Greek yogurt is very dense and one measuring cup of it will weigh more than 227 g.

                              1. re: Cathy

                                If 227 grams is one cup, then there should be four cups in the container.

                                The original post says the tub contained 3-1/4 cups. If the container was not short, that would mean that a cup would weigh 9.85 ounces. I'm skeptical that any yogurt is that dense.

                                1. re: Robert Lauriston

                                  Maybe they are using the definition of a "cup" that is used by most coffee and coffee machine manufacturers: 6 fluid ounces. :)

                                  1. re: Robert Lauriston

                                    The idea behind "Greek style" yogurt is that it's more dense than regular yogurt (essentially strained yogurt) so it has a higher density overall. Yogurt is a grey area as far as standardization goes. Single-serve used to be 8 ounces years ago and most cups sold are in the 6-oz range (some are 4). Quarts are still common.

                  2. re: Jeri L

                    That sounds good until you measure it with a measuring cup. 3 1/4 cups is what comes out.

                    1. re: sobon2

                      YOU DO NOT USE A MEASURING CUP FOR LIQUIDS. You measure by weight. That is why you are seeing a difference.

                      8 ounces of water will not look the same as 8 ounces of maple syrup. Neither will look like 8 ounces of yogurt.

                      One measuring cup of sugar will not weigh the same as one measuring cup of cornstarch.

                      Dry is by measuring cup, wet is by weight.

                  3. IMO, Costco Greek Yogurt tastes as good as Fage. Costco is held to the same standards of weights & measures as other packagers of products, liars??? I think you need to brush up on on this subject before accussing Costco of such practices. Since this is your 1st post on CH, I'd suggest caution before creating such a topic.

                        You might not like the responses, but it's your premise that's flawed.

                        1. re: sobon2

                          The the label states: Servings per container about 4 but, don't over look the net weight of 32 oz. A cup is a half pint of liquid, 8 oz, and the container has 32 oz, sounds like 4 servings at 8 oz each. Please get back after you file your law suit against Costco and all the other food packagers in the industry.

                      2. Assuming that as reported the container says 32 ounces and the nutrition panel says about four one-cup servings, there are several possible explanations:

                        1. A cup of this yogurt is so much denser than water that it weighs almost ten ounces. If that's the case the nutrition panel is wrong about the number of servings and maybe other things as well.

                        2. The container is mislabeled as having 32 ounces by weight when it actually contains some lesser amount, such as 750 grams (a common container size, which is about 3-1/4 cups).

                        3. That particular container was short.

                        You'd need a scale and a fresh container to narrow down the possibilities.

                            I just saw a 13.25 oz. box of Barilla Wholewheat Pasta, the label stated serving size 2 oz., about 7 servings per box, the nutrition was displayed for the serving size of 2 oz. So I guess the last serving will need to be prorated. I always use a scale, a great investment.. BTW - I take offense at Costco being called a liar, sobon2 I believe you should email the CH mods and refine your topic title to retract your reference as Costco being liars.

                              I've always taken the "serving size" verbiage to be there for the purposes only of caloric intake information. Not, on the other hand, to promise that one was going to actually get each and every one of those number of servings out of that box, bag or can... YMMV
