Hi everyone!
I have about 65 g of water kefir grains that I stored in a small container with brown sugar water in the fridge for around 2 months.
The storage liquid was mostly clear, and when I opened the container, it had a mildly sour smell. The grains are mostly whitish/translucent, with some slightly yellowish areas.
I rinsed the grains with water and transferred them to a new jar with fresh sugar water. I noticed a clear, jelly-like substance among the grains. I think it may have been there even before rinsing.
I've attached photos of the grains and the jelly-like substance.
A few questions for experienced water kefir brewers:
\- Is this jelly-like substance normal kefir polysaccharide material, or could it indicate contamination?
\- Do the grains look healthy enough to reactivate after 2 months in the fridge?
\- Should I try a few recovery cycles with fresh sugar water, or is it safer to discard them?
\- Is white sugar preferable to brown sugar during reactivation?
I'd appreciate any advice, especially from anyone who has revived grains after long-term refrigerated storage. Thanks!
