Shelf life

[smugface]

I just started home brewing. I have found so much info here but still have one question.
What has a longer shelf life?, raws or finished product?

Both are very long lasting
but raws last even longer, as they don't have any other, different molecules to cross-react, everything in the bottle is the same substance.
finished gear: 5+ years
raws: 10+ years

Thank you.

From a big-pharma raws manufacturer:

Storage: In the original container, well closed, in dry and well-ventilated facilities, protected from direct sunlight at temperature between 15° and 25°C.
Re-test period: Three (3) years from the date of manufacture.

A lot shorter than the 10 years you originally claimed BUT of course pharma will always be on the safe side and say 3 years to retest.

What I did notice though is that it's meant to be in dry and WELL-VENTILATED facilities. I know some people like to vacuum seal their raws if they're going to sit for a while.

Also between 15° and 25°C it means 59° to 77°F meaning that anyone that suggests throwing your raws in the freezer is wrong I guess. I do know some people like to do that too though..

In the original container

What is an adequate"original container" if your raws come I bags.

From a pharma.. I'm guessing air tight containers.. Maybe as I mentioned before vacuum sealed.

I wonder if they say retest to "overdose" the final formulation?
i.e. if raws were 98% pure when new, and it dropped to say 95% in 3 years, they adjust their "overdosing" compensation?

OTOH it also means that raws are totally OK for at least 3 days, if stored in dry,cool, dark conditions.

Ah you may be right.. Good catch.
