Default OG readings effected by sediment?

I was wondering if suspended sediment in the wort in any way effects hydrometer readings.

Any ideas?

I'm trying to understand your question, but have one of my own: Why would you measure sediment?

What's the condition/situation you are looking at?

Im not... I am wondering if particles in suspension in any way throw off the gravity readings of the wort..

The more particles in suspension = less water in test jar by volume.

However now that I think about it, it doesnt seem to matter what volume you test when you take a reading so maybe it doesnt matter.

Don't feel bad Whammo, I have wondered that on several occasions. Especially while making a IIPA, the 8 ounces of pellet hops suspended in solution would seem to have some sort of effect, right? I didn't really worry about it too much though, it tastes great and the abv is definitely there .

Sediment does not affect the gravity reading. If it is in suspension then it seems to be almost as dense as your wort/beer and it it's on the bottom then it is on the bottom. Only if it floats on top I could imagine it throwing off your reading.

Stuff floating in the sample doesn't change its density - only dissolved stuff does. So floaty bits won't change your reading.

Well, I'm not quite sure about this. I know that foam, especially dense one, surely affects the reading. I just wanted to play on the safe side.

The only thing you really have to watch out for are bubbles on the hydrometer .

What I meant to add was...

...unless stuff sticks to your hydrometer (this includes foam sitting on top of the sample). Then it will throw off your reading. Otherwise though, what I said stands.
