Aside from the fact that using a bung entitles me to call the mouth of my carboys a bunghole , I'd prefer to use carboy caps in every way. They're easier to get on, off, and facilitate easy, sanitary, siphoning. More than anything else, I don't have to wait for them and the inside of the carboy's mouth to dry before they'll work--rubber bungs tend to slide out if they or the carboy mouth is at all moist.

Are they sufficiently air tight, though, to prevent microorganisms from sneaking in, and to protect my brew and wine from oxidation? I know the EdWort's Apfelwein recipe mentions using them, and so, in careful fidelity to the recipe (and because the better bottle stoppers are so expensive), I've used one on the batch I have going right now. But if they're sufficient for general use--I am so tossing all my bungs!

You can also use carboy caps as part of a siphon set-up.

I like bungs myself because the airlocks only clear my lager fridge if bungs are used instead of carboy caps.

More a question than a testimonial at this point--I'd -like- to use them for just about everything, but I'm worried that they're not sufficiently air-tight to keep out invading microorganisms and O2.

They are airtight, if you get the right size. Orange for 3,5, 6 gallon carboys, and red (I think for the 6.5 gallon). I use them about half the time.

I like the siphoning idea. I think that I will pick up a couple tomorrow when I go to the brew shop.

I'm a HUGE fan of carboy caps for Better Bottles. My starsan soaked rubber stoppers would always pop out. My carboy caps just pop on and stay on regardless of a wet carboy neck.

I think cap are better than bungs at stopping microorganisms even if they are a bit loose. Microorganisms usually ride on dust. With a bung dust will settle around the top lip of the carboy. As soon as you remove the bung bad things can fall into your beer. Caps cover the entire top of the carboy and keep those bad guy guys out.
