I bottled my batch of dark IPA last week and I checked the bottles yesterday and they have an obvious haze inside the bottle where the beer is. I thought I would try it to make sure it didn't taste funny. It tasted fine to me so I'm not sure what it is. This was my first batch with using starsan and I was wondering if the residual froth from the sanitiser affects the beer in any way? It doesn't look very nice in the bottles

Does anyone have any idea what has caused it?

How many times have your bottles been refilled?
Sounds to me like beerstone, which is a hazy calcium deposit on the inside of your bottles.
I get it in mine after a few refills, and just clean it out with some hot water and a bottle rush.
Alternatively, I believe you can give the bottle the sodium percarbonate (napisan) treatment, but I've never done that myself.

It could also be something innocuous as yeast and other substances attempting to drop out of suspension, but clinging to the side of the bottles.
A quick back and forth spin should dislodge it in that case, and it will then drop to the bottom of the bottle.

One thing is certain, it is nothing to do with Starsan.

Its just weird, I havent had this problem before. But I have also never brewed an all grain beer before or a high alcohol one.

It just doesn't look very nice having a film inside the bottle. It also makes the beer really cloudy.

Did you gelatine it or use finings of any kind?

Mine stuck to the inside of the bottles (all over, not just the bottom) when I got a bit heavy handed with the gelatine a couple of times.

No I didn't use finings. This is the first time that I have ever had this problem before. My only drama is that it doesn't look nice in the bottle. It could possibly gave strange tastes to it but its a dark IPA and I also don't know what I am meant to be tasting
