Only trick with dry hopping is to stop the hops from getting contaminated. Specifically, i think someone here, (the Pol?) infected his batch when he used a scale with grain dust on it to measure the hops. Keep your grain and hops as far separated as possible, (I give my scale a good spray down with cleaner/water/starsan before weighing hops), and you should be fine.

The powdery substance was sort of a blue/gray dusting on the top of the surface. I wasn't able to get a sample of it unfortunately. I wish I had a higher quality camera.

I think I have good reason to think this batch(and others) have been infected.

I doubt it was bacteria on the hops. I think it is more likely that my apartment is incubating a number of bacterias, or wild yeasts, that are getting into my beer when I rack from container to container.

My Final Gravity on the I.P.A dropped from 1.014 to 1.010 after I racked it the last time. This was after sitting at 1.014 for a couple weeks.

Does anyone have any idea how I can keep dirty air from infecting my beer? Rack outside maybe? This is getting very frustrating. I believe I've had an infection in my: Christmas ale, Blonde ale, India Pale Ale, and Chocolate porter.
Prior to this fall, and moving into this apartment I've never had any problems like this, unless I was extremely careless about cleanliness.

All four of those beers seemed very healthy, until I racked them. Then fermentation seems to restart, but with all kinds of gross, out of the ordinary characteristics.

Can anyone shed some light on this for me? It is extremely frustrating to think I wont be able to brew until I move again.

I have no experience with wild yeasts, but I bet you could purge each container, (carboy, ale pail, even bottles), with CO2.

Something like this:

With a bit of tubing would allow you to purge your vessels on the fly, without a huge equipment purchase.

Dunno if it will help or not though
