Shelf-life, or best before dates, for various items used in brewing or wine-making would be interesting perhaps.
For example, I learned recently that Iodophor has a shelf life:
* A whole bottle is good for "about a year"
* A new solution (1 drop per liter or 1/4 gallon) is good for about 24 hours
But does this mean it is completely dead, or just "wounded" -- could I say double the dose of my iodaphor at the 1 year mark, or does it turn into a pumpkin on day 366? How long as it been sitting in the wine supply place before I even bought it...?
This also caused me to ask.... how about my yeast nutrient? My yeast? Yeast energizer? Pectic enzyme? How about the whole wine kit I bought 4 years ago? Potassium Sorbate? K-Meta? Etc.
Lots of folks assume that anything chemical or packaged lasts forever, but that's simply not true, and storage conditions may have a great effect.
Well... let'r rip!
