Grocery Shrink Ray Hits Folgers, Makes More Cups From Less Coffee?
Here's a fun little mystery for you guys. How can taking away 4 oz of coffee produce more cups of coffee? We've been thinking about it ever since Blueprint for Financial Prosperity sent us this photo the other day, and we just can't figure it out. Could it be magic? Some strange new property of the Grocery Shrink Ray?
Blueprint for Financial Prosperity says:

I bought a can of Folgers coffee two days ago from Costco. When I compared it to my last can, also from Costco, I saw that the new one had 4 oz less of ground coffee. Ok, no big deal, but then I saw that the small can claimed to make more coffee than the larger can. This is the first time I've seen a company shrink their product but claim you get more. It's not a matter of coffee potency either, the preparation instructions are the same.
Now we're not math geniuses or anything here, so please do let us know if we're missing something or messed this up but, the preparation instructions are in tablespoons (volume) and the product is sold by weight... but the ingredients say that both cans contain 100% pure coffee. Has the density of coffee changed lately?
Hmm, let's see. ?=m/V, and 1 tablespoon is 15 cm³... 360 6 oz cups...
By our calculations, the old density of Folgers coffee was .272 g/cm³ and the new density is .238 g/cm³. Did you guys get the same thing?
The shrink ray is getting more complicated all the time.

@Applekid: I think that's the most reasonable possibility. It may or may not be true, but it at least makes sense.
I know how you can get 1000 cups! Just add water!
@kidincredible:
haha, or you can not read the article in the first place and not understand the confusion
i = fail
Folgers drinkers must like their coffee weak, anyway. Most other brands of coffee, as well as coffee maker instruction manuals, recommend 2 Tbs per 6 oz serving. From what I've read, ground coffee is about 5 grams per Tbs so 3 lbs (1360.8 grams) divided by 2 Tbs (10 grams) only makes 136 cups, not 380.
@failurate: I'm going to join kidincredible in the failure read the article/look at pictures corner of shame.
@kidincredible: @failurate: Don't worry, that's exactly what I thought the first time I looked at it.
@kidincredible: ha ha pwnd.
even a different grind doesn't explain how you can get more following the same directions...

Basically, coffeemakers have been hit with the shrink ray too. A "cup" of coffee has been (re)defined as 5 oz.
So your 12-"cup" coffeemaker makes 60oz. of coffee, or 7-8 8oz. cups of coffee.
@wickedpixel: I suppose, but they didn't change the per-cup measure; how are they arguing that there are 380 tbsp of grounds in a smaller canister than one with 360 tbsp of grounds in it?
Granted, most people don't make coffee by the single 6oz. cup, but still.
It says it makes "up to" so many cups, not that it can make that many cups. So they just raised the ceiling, not the floor. Technically speaking, it can make UP TO 1 million cups, which means no more than 1 million cups can be made from that can. And that's true.
I'm pretty sure that's the BS marketing logic. :P
@donopolis: sure it does. The directions use tablespoon, which is a measure of volume, the container itself is measured in lbs, which is a measure of weight. They are unrelated measurements.
See kids, math is important.
@sean77:
I concur. But it certainly is the sneakiest use yet of the Shrink Ray (and yes, I'm one of those people that's completely sick of it).
There seems to be a double shrink effect going on here, unless they've found a way to pack more flavor into less bean.
Maybe if the poster would have taken a scoop from the old coffee and compared it to a scoop from the new coffee, we would have a better picture of this mystery. If they reduced the amount of the same coffee, then chances are that they would also reduce the size of the container to avoid the visual impression of getting less coffee. The containers look to be the same size, so it might point to a new processing technique. Explore all angles first.
Unfortunately, many get caught up in the hysteria before getting to that point.
Meg, I believe you truncated instead of rounding to the nearest decimal. Although this is not a material error, it's still important that I had to lower your grade to an "A-".
Using volume for measuring dry goods is a sham anyway. I can show you a tablespoon of Folger's that weighs 4 grams and another tablespoon that weighs 7. The fudge factor that changes 360 cups to 380 cups is well within the packing margin of error.
Who would actually count the number of cups it makes and write back to complain. They label is designed to make you want to grab the package with 380 cups on it and put in the humongous shopping cart. It appears even more absurd to me, because I have been roasting my own beans for years. The cost $3-$4.50 a pound. No comparison.
Somehow they squeezed an extra 5.96 ounces of prepared coffee out of every ounce weight of coffee.
@MrFreshy: but what if it's sawdust from the coffee plant stalks? eh, smart guy?
Randomly, this has happened every time the price of coffee has dramatically increased for the past 100 years... They suggest "use less coffee" or "re-use grinds" -- I saw the ads in a book called "higher grounds", but I'm sure you can find them on the interweb if you look for old coffee advertisements.
A coffee cup is officially calculated as around 5 ounces I think, I can't seem to find it online after a quick search (Anyway between 4-6).
Coffee producers stop planting when the price is low, and plant extra when the price is high. The problem is it takes 3 years for a plant to start producing enough beans to pay for itself, and by then, 3 years of heavy planting means the price drops dramatically for a few years so they stop planting until old trees start dying off, demand exceeds supply, and the planting starts again.
This is one of the main reasons to buy fair wage coffee -- the price is guaranteed so they don't boom/bust as other coffee plantations have for over 150 years, leading to a more stable planting policy with an emphasis on using the land for a lot longer, leading to more ecologically friendly plantations.
@donopolis: Coarser grind = more air pockets between each crystal = less density = less weight for the same volume.
Any questions?





















Couldn't a more coarse grind lower the density?
