In the package
A note on branding… When this review was first published these swing top caps were ToteGlass brand. They were very popular with HBF readers. They regularly sold out when I posted that they were available. At some point they just stopped coming back in stock. That lasted for months. That is until Valuebrew started carrying them. According to the product description, they worked with the manufacturer to bring them back!
The completed assembly consists of four pieces. A screw on base, a bail wire, a stopper cap and a gasket.Assembly InstructionsOperation InstructionsStep one is to remove the bail wire from the base adapter and screw it on to your compatible growlerNext you reattach the bail wire. Whammo you’re done.A look at the installed adapter assembly. Note that the gaskets can be removed for cleaning and replacement if needed.The swing top cap features beefy food grade gaskets that feel secure and tight when the lid closes.Installed on a standard glass growlerInstalled on both a standard size growler and a smaller 64 oz grumbler.Installation tip: This is a good illustration of something not to do. The adapter ring is installed such that the wire bail is lined up with the growler handle. This stops the wire bail from engaging properly. Tighten the ring a bit more or loosen it a bit so that the wire bail can close.Properly installed and aligned adapter ringA benefit of these is being able dress up and upgrade a standard growler. Most of us probably have some fancy growlers and sometimes we can’t use them. This growler is an example. it’s a brewery located close to a family member in the Twin Cities. If I’m going to get a growler filled there, I have to use their growler. This can be the case due to brewery policy or because of local laws. This upgrade gives you a the ability to upgrade must-use sorts of growlers. Note that this flip top may not be compatible with heat shrink sleeves.
A big question for me was… does it work? Does it hold carbonation? To test that, I filled a swing top equipped growler and let it sit for two weeks. The contents were nicely carbonated at the end of the test.
I don’t have any empirical evidence, but I do believe these seal better than standard growler caps.
The gasket material inside of standard caps just doesn’t inspire a lot of confidence. It’s like a sprayed on gummy gluey substance that just makes you question… what is this stuff? The feel when I tighten one of these downs confirms my concerns. I feel like I have to wrench them down with all my might for a chance at a good seal. Not so with these flip top caps. They feature beefy food grade gaskets and seal securely and tightly.
Of course, I didn’t read the operating directions to begin with. As a result I struggled to get this to work smoothly. Here’s another look at the operating instructions…
The swivel motion of the cap that’s illustrated here is important. Once you get that down, this cap is easy to use. What you’re wanting to do is spin the cap as you lift it up. That puts it into the correct position to engage the wire bail. When opening, you’re doing the opposite.
These are a nice upgrade to standard growlers that glass growlers up a notch in terms of look and function. They feel and work better than standard caps and the fact that they can be disassembled for cleaning is a plus. I believe these actually give you a better seal than standard growler caps. These are easy to install and uninstall so you can switch between growlers. Because the cap stays attached to the growler… you won’t lose or drop your growler cap.
Even though I may have some fancy growlers, good ole glass growlers have their place. Glass growlers are cheap, do the job and in some cases are required if you’re wanting a growler refill. It’s nice to see these faithful friends get some bling.
