Fermentation colour change ????

[Madmannvan]

I've always done primary in a bucket, so I've never watched the yeast do their thing, but on my last brew day I used my carboy. After day 2 this is how it looked View attachment ImageUploadedByHome Brew1446650277.448314.jpg

Then on the morning of day 4 this is what it looks like???View attachment ImageUploadedByHome Brew1446650351.388294.jpg

Is this normal?

Yes, it's suspended yeast and other particles.

It has gone bad. You'll need to wait for it to finish fermenting, bottle it, and send it to me for disposal.

Totally normal. That is the yeast and suspended solids churning around. Worry if it stays looking like the first picture because then it is likely that there is no fermentation.

Thanks for the help. There was all kinds of yeast and other particles swirling around in the first picture so I thought perfect it's fermenting then when I saw the colour change so much I didn't know what was happening.

This is wild yeast off grapes, I've done a couple small tests with it that turned out well so have stepped it up to a 2.5 gallon batch. Can't wait to see how it will finish
