## Questions & Answers

**Q: is there an expiration date?**
A: We go through a lot of this so we are constantly rotating our inventory. After purchasing, the shelf life should be at least 5-6 months before it will start to lose potency.

**Q: Will this remove the yeast taste? I've had bre**
A: Unanswerable.  The cause of the yeasty taste and when caused in the brewing process would need to be known.  But, properly sterilized equipment should prevent previous batch contamination.
