I did the cardinal sin tonight. I racked 2 wines. When I was done I was washing the second racking tube and I noticed a 4 inch dirty section just below the bend in the cane. I racked 2 wines through that dirty racking tube. Luckily, hopefully, they were done fermenting.
I don't know how it happened. I rinse everything when I am done using it and then I wash it.
I have said racking cane now soaking with B Brite. I am not sure how to get it 100% clean again.
I could never use non see through equipment. I have to be able to see where the dirt and nasties hang out.
Has this sort of thing ever happened to you ?
