Good for long term aging Review by Sample

After transferring I leave the stopper open so dissolved CO2 can vent over time. But after a few weeks I seal it shut and no O2 can get in as it ages 6-36 months.

Two in one for carboys Review by Redmond

I'm a fan of having one thing for multiple purposes rather than 2 or 3 separate
units. It's functional for both purposes and I use it all the time.

It does what it's supposed to do Review by William

It does what it's supposed to do, but I already had a solid bung, and a drilled one. It's ok, but a solid bung would be just as useful.

Not worth it Review by Huber

For the price I am better off buying a solid stopper, for long term aging. I used it all of this year, but now I just use a solid stopper that cost less. If I have to age multiple batches I can still use it, but I wont going forward.

It'd beter to have 2 good things than 1 that's just so-so Review by William

Good idea that fails in execution. I'd say stick with a drilled and undrilled stopper and an S-lock. Its for carboys only.

I wouldn't buy it again Review by Nadim

(Posted on 9/4/13)

Product Rating:

One stopper for two purposes - an air lock and a stopper for aging. It's ok but for the price and functionality, I would buy the 2 individual components instead, and for less money. The 3 piece air lock and drilled stopper is better than this at what it does.

1 is not always better than 2 Review by Jon

Its a good idea, having one stopper than can serve 2 purposes, but after using it I prefer having 2 distinct stoppers. It doesn't fit Better Bottles either. I would not but it again, nor do I use it any longer.

For long term aging, with a carboy Review by Dunn

(Posted on 5/19/13)

Product Rating:

It can be used during fermentation, and can be sealed up for long term aging. This si well suited for Lambics and Russian Imperial Stouts, which have a high alcohol content, and take a while to mature. Even so, I think it better to have 2 specialized stoppers, each designed for it's intended use.

For long term storage Review by Phoebe

Product Rating:

This one stopper serves the purpose of 2 stoppers, one solid, one drilled. This is useful for Lambics, lagers, and Imperial Stouts, all of which are fermented and then aged for a long time.
In my opinion you would be better off using the 2 stoppers than this. They are each better suited for their task than this is for both.

Manual Actuation Review by Harold

(Posted on 1/10/13)

Product Rating:

This was not quite what I expected. Basically this is a solid silicone stopper with five holes in it. Four holes are spread radially around the center, and the fifth goes through the center. On top there is a silicone cap, with a silicone "stick" that you see in the picture.

To seal you have to pull on the stick to make the cap be flush with the top of the stopper. The first time I did this it took a little work to get the sliding action, I am not sure how much pressure would have to build up to create this. It might also be possible to reseal by pushing down on the cap, but I have not tried this yet. For the time being it seems you might have to remove the stopper in order to reseal it.

Overall I will still be using this, but like another reviewer it will more or less be restricted to use on my 3 gallon glass. Glad I tried it, but for the price I would just get a bunch of solid stopper next time.
