Peanut butter is an awesome high-energy food though it does have a somewhat limited shelflife.

Working in the food distribution industry, I was noticing a drop in the volume of peanut butter this summer but I did not know what was causing it.

I thought peanut butter was pretty much bomb proof. If it seperated, mix it back together. The use by dates were there for freshness and taste - or so I thought.

I'm a commodities trader by profession and I can verify what Blast has posted. If you eat peanut butter, go ahead and buy a year supply now.

I'll add that I don't think you should buy more than 1 or 2 years supply though. This is only a temporary supply disruption. It takes a different kind of market disruption, like a geopolitical event or a sudden and permanent spike in labor costs to permanently drive up the cost of a commodity. Peanuts did not experience that kind of disruption. Peanuts just had a bad harvest and should get back to normal with the next good harvest.

The fats in peanuts oxidize (goes rancid) fairly quickly, usually in 9-12 months.

I can't eat peanuts. I wish I could because I love peanut butter and banana sandwiches!!!! Fluffer-nutters are also awesome. So, good riddance!!!

The article does not mention what the shelf life is if the container remains sealed.

Anyone know what the storage condition specifics are for the shelf-life statements?

Most PB containers I've encountered have a foil seal thats concave which indicates to me a vacuum, or at most a very minimal amount of oxygen in the lid area. I'll bet low temperature storage would be beneficial as well.

Also, I never buy "adulterated" PB ie: brands with added oil, sugar, stabilizers etc.

I only buy PB which is made from nuts and a little salt. Those are the only two ingredients on the label. Sure, you have to stir it but usually only once. And I never have to put it in the refrigerator either. It gets consumed within a couple of months after being opened.

After eating this kind of PB for years I got a dose of one of the kids' stuff brands and I almost vomited!
It tasted horrible with all the added sugar and oil. It literally tasted like greasy, peanut flavored candy.
I know I loved Jiff when I was a kid. "But when I became a man..."
Sorry, just a little legumor there.

In my opinion, that extra stuff is added for two reasons:
1. To make kids like it (brand loyalty conditioning)
2. To make it easy to spread (parental suffering reduction)

Thanks for the heads up Blast. My family practically lives on the stuff!

To be honest, I have not looked that closely to the dates on peanut butter. If it will help, I will look at some jars of peanut butter when I return to work Tuesday.

Commercial peanut butter, unopened= 2 years according to this site. http://www.stilltasty.com/

You should try almond butter. Much better IMO. It is more expensive, unless you make it yourself of course.

I was just thinking--if peanut prices do rise by a third, maybe almond butter suddenly becomes price competitive with PB to many consumers. Interesting. I love almond butter.

I've been buying nut butters for food storage (and eatage!). Delicious, and the jars take up very little space in my apartment.

In addition to peanut and almond, I like sunflower seed butter, and cashew butter as a special treat. I recommend the "Once Again" brand. No affiliation...

Yes, Almond Butter rulz

I was told by the doc to avoid all nuts....I can just tolerate sunflower seeds.

Is this an improvement over "SunButter"? That stuff is so runny it is useless. I could almost eat it with a straw - very disappointing.

With the Once Again nut butters I've tried -- When you open a new jar you have to mix up the contents with a spoon or spatula, because the oil has separated out. That requires a bit of patience. But then you store the opened jar in the refrigerator, and no more mixing is needed.

I can't comment on SunButter because I've never tried it...

Well them couple o' weeks are here allright & I saw Jip for $4.69 at Pavillions today(12oz jar),All the others are right up there too!Planters dry-roasted in the glass jars are over $5.00 also!
