I honestly don't know about the red feather product from personal usage, but as I recall, they use a canned tin , and not one of those "Lift and pull tabs".
Oils and fats turn rancid when exposed to oxygen
The two year date is a "Reccomended Use By Date" by the manufacturer.
I am in the process of using and donating all my "Lift and Pull Tab" cans because they are untrustworthy for long term storage.
I am storing regular off-brand store products that don't use the "Lift and Pull Tabs", even though they are made in the very same manufacturing plant under same conditions.
The can seal is my main concern for long term food storage, along with flavor and taste
I would contact the manufacturer or the distributor where you got the product at their toll-free number for specifics on expiration date and usage date.
Well the info I have read is that the suggested use by date is two years from date of purchase (as long as purchase is made from a regular retailer of the butter). Regular canned tin. I have them stored at approx. 65+/- degrees year round downstairs.
My ONLY concern is the whole oils and fats thing. Red Feather is purported to be an excellent product. I think I will remind myself to open one of the older cans and have a look at the contents. Might feed some on a cracker to the hubby if it has a good appearance and no off odors. :) Just don’t know WHAT to do with them if they seem OK, but I don’t want to hold them any longer. Seems a shame to toss them if they are viable. Prepper problem!
