Does anyone Know how long the shelf life is ? I found some in the cabinet that I bought in 2010. Wondering if it will still work

Actually, I've mashed for a very long time and never used the stuff. But, that being said, I know it works well in the mash from others...getting more fermentables, etc.

The stuff isn't cheap, but I wouldn't use it. It might be just fine, but I wouldn't take the chance. I'm guessing you haven't used it for a while for a reason...and I'm sure you're still distilling on a regular basis...?

Hope this in a small way helps...

Hi diesel,

I'm assuming that you're using the powder that Rick sells (the BA-100). Here's what the spec sheet says:

"SEBamyl BAL 100 should be stored in a cool, dry place. Storage in unopened containers, at or below 10 C, helps to maintain maximum activity if stored over long periods. Under these conditions, activity loss after one year should not be more than 5 – 10%. Extended storage under adverse conditions, including high temperatures (>10 C) may require the use of higher than recommended dosages."

After six years at room temperature I'm guessing it's probably played out.

If you still have a lot of it & want to at least do some experiments, steam/cook a cup of rice, add some water & bring it up to 55 C, add a tiny bit of the enzyme (about 1/8 - 1/4 tsp), wrap in a towel & let it sit overnight. Drain the next day an take a gravity reading (keep in mind though, that some of the density will be from hydrolyzed starches that didn't convert). If you want a better reading, refrigerate the wort & let it clear (may take a week or so). Also, without the gluco you're likely to have a bunch of unfermentable branches in the wort.

Regardless, after such a long time on the shelf, I wouldn't plan a mash that depends on it ... no sense burning your time/money on something that is likely not to succeed.
