47324Re: Rum Wash
- Nov 7, 2010Saved it...
In frustration last week I decanted 2L of wash & mixed it with 2L of water into a bucket, watched it for a few hours, nothing, so I moved it into the "wash" room and left it. Looked at it over the next few days as I was on my way to work...nothing...then checked it for the last time yesterday before getting ready to throw the lot out and it was off and running.
Why it has taken so long to start fermenting is a mystery.
So, I have decanted 10L of inactive wash, added the bucket activated to the remainder and topped it all up with fresh water. Fingers crossed, it's a slowly fermenting.
Rum "mother" saved.
