Has anyone tried using the oxygen scavenging / absorption caps? The should (in theory) lower the risk of oxidation for bottled beers. I've started using them on the past two batches but haven't bottled any with the old caps as a control.

Oxidation hasn't been a problem for me over my past 45 batches, with several bottles aged for over a year as well. I only got these caps more thinking of them as a cheap insurance policy for hoppy or aged beers.

I don't know how well they work, and they recommend you don't sanitise them which is odd. Clean and sanitary are different things, but that's just me.

Capping on foam and PET bottles helps for beers you won't store for long periods.

Pet bottles, squeeze all the air out before you fully tighten the cap not sure it makes any difference but it makes me feel better about it

luxo_aussie is in luxembourg. he's probably got a shed full of 500ml brown german swing-tops in plastic crates.

Plastic crates yes, swing tops no. 27 crates of this.
for me, plastic crates for 500ml swing tops for 500ml (SOOO much faster and cheaper on capping), i think all up i've actually got 27 crates too haha. got the 330ml crates off a japanese restaurant mate.
so i use 500 swing tops for higher rotation and 330ml caps for stuff i'm going to age, at 30 bottles per crate. super handy. got about 30 fensburger 330 ml swing tops but they're a bugger to store. as wide as a 500ml bottle so they won't fit in the smaller crate compartments. i thought you'd be rolling in swing tops LOL.

It was a hard decision but was concerned with the degradation of the rubber over time on the swing top caps and with this not knowing if one bottle had gone through 6 batches vs. one which was brand new without a detailed inspection of each before bottling. The caps just get replaced each batch so there no need to check anything aside from the bottles being clean. Do you replace the rubber very often?

if it's just too easy to clamp the cap on when bottling, i replace. but, when i was collecting bottles from a club-restaurant bin, there were always broken swing-top bottles , so i cannibalised the swing-tops and never had to pay for a new seal. i've got about 400 swing tops, i've replaced maybe 10-15 swing top units in the 6 years i've been using them, and i've got about 50 complete units sitting there. i think they've all gone through an awful lot more than 6 batches, i'm guessing comfortably more than 20 for a lot of them.
on the other hand, capping my longer term beers was an insurance policy i engaged in when i was a bit nervous on swing top seal degradation. now it's partly habit, and partly just cos i like the aged, often higher abv's in the smaller bottles. feels a bit more of a treat when i have one.
for a detailed inspection of the seals, you'd need better eyes than me LOL. when a swing-top starts going soft (easier to clamp shut), i mark the lid with a waterproof marker to keep an eye on it. it is quite noticeable how much softer it will go from one capping to the next.
and the other bonus when sanitising bottles on a plunger is - the caps are attached to the bottles, so they get dunked in the sanitising as you're going along. there's not much to not like about them.
