Default Dry Hop Questions

So I read Vinnie's quickie on Dry Hopping from Extreme Brewing (Russian River Vinnie). He mentions shaking up the fermenter to re-introduce the settled hops (a few days after dropping them into the secondary).

What are the biggest concerns here? Do I have to worry about Oxygen at this point (Hopefully there is a layer of CO2 to help)?

Is it a bad idea to shake up the yeast? Being that they are living organisms, would the rattle cause any harm?

I've never thought to do that, but it sounds like an interesting idea. I guess the key would be that you'd need to let it sit and settle long enough for the yeast to drop back out. Which if you're only doing after the first couple days wouldn't be much of an issue.

Personally I like to use a weighted hop bag that's suspended in the middle. I have no idea if it's beneficial or not it's just what I've always done.

i think shaking should be done differently. Shaking it could introduce oxygen so i would be careful with that.

If it were me, I would stir it gently to "shake up" the beer

That's a good point. There isn't much sediment, other than the hops. This would also keep whatever CO2 layer in place.

Thanks

You wouldn't harm the yeast, but you could definitely get oxygen back into the wort and oxidize your beer...

At that point, there shouldn't be any oxygen in your fermenter.

How do you do this? Last time I dry hopped, it overflowed everywhere and sat on the top of the fermenter.

Well, it's been transferred to the secondary with a lot of head room. So I'm assuming that a little bit more C02 has been released, but probably not enough to completely kick out all Oxygen.

Once you put those hops in though, CO2 should be pouring out of it. It should be taking CO2 out of suspension and pushing it out, which should push out any oxygen you have in your fermenter. Similar to dropping a mentos in a bottle of Coca-Cola.

You could sanatize some marbles and put them in the bag with the hops.
