Is 16oz the volume to the very top? I like to freeze broth in 16oz portions, but need some expansion room. Will these work?

Yes, the 16 oz volume means to the very top. I just put 16 oz of water in a 2 cup measuring cup. The water filled the canning jar to the top edge.

I freeze jars all the time. As long as you leave head room for expansion there shouldn't be a problem. Also, no huge temp changes! I wouldn't put hot leftovers in a jar, seal it, and freeze it. Nor take a frozen something out to the microwave or oven. As long as you have decent quality canning jars, they survive well!

They work very well. Just don't overfill, because the contents do expand in the freezer.

I have not tried them in the freezer. I would use caution - do a test on one first. Some Bormioli Rocco jars have "shoulders" which can create pressure as food freezes and expands. You would want to leave a 1" headspace for sure. If you are freezing liquids like broth use caution - they expand the most. Freezer jams do not freeze solid and so tend to expand less - if you leave the 1" headspace they would likely be safe. Fresh / dried herbs (not covered in liquid) would be fine. When storing jars in the freezer it would be good to ensure the jars do not bump into each other - perhaps use the box they come in to keep them protected and make it easier to rearrange the freezer. I will try a test with plain water and report back. :D

Sorry to hear that.....because I do a lot of 'canning' I can guess that you did NOT leave enough 'head' room or space for the unit to create the pressure it needed to process. Most units require that it be filled not more than 1/2 way.....just like a fryer....you need room for the expansion. Hope it didn't make too much mess in the kitchen and you were able to save the contents (what were you making ?) Mine stopped working after less than a year of use (I used it maybe 5 or 6 times) .....returned it.....however, when it was working, it did great. Not sure I'm going to get another just yet. Hope this was helpful.

I have used them to freeze leftovers. As long as there is enough room left for the contents to expand when frozen, it should be fine.

As others have confirmed, a SMALL one! The Unison line is all undersized. The designated volumes for the pots may be literally correct, but don't try to actually put those amounts of ingredients in them.

I just used a Pyrex to measure, and it can hold 6oz and still be easily closed. You might be able to get 7 oz in there, but it may be harder to close it depending on how liquidy your item is; I've stuffed it full with 7oz of thicker food and I was able to close it, but just barely, so I'd say 6oz is a good average. 6oz also works for freezing them, since you'd want to leave extra space.

No. It will be 18 oz in volume, but still 16 oz fluid and and 8 oz. solids. It's the same concept as making a bottle.

You can freeze liquids, but don't fill too high because liquid expand when frozen! Fill to about the bottom or just little lower than the jar lid edge. You can feeze liquids in mason jars as well and there's a "freeze line" just below the lid.

if you freeze the bags flat, they are too wide for the container. They do, however, fit very well into the top.

Absolutely! Just make sure you save room at the top for expansion. I'm ordering more bottles today. Every Sunday we make fruit smoothies for the week and freeze. :) Excellent product.

I put mine directly to soak in vodka to make my own vanilla, so I can't help you on this one. I would hesitate to freeze them, though. My gut instinct just says it might not be the best thing. Looks like the other comments are split 50/50.

32 ounces however that does not allow any room for expansion when freezing soup, etc.

I only have one of the 14oz ones so obviously can't try stacking them, but do have multiples of the larger, 16oz, size. The larger, 16oz size barely stacks (in that they fit inside each other, but only about a third of the way. They also seemed to fit too tight for my tastes (would likely be difficult to get them apart if stacked too firmly/long).

I was wondering the same thing. I was about to buy it until I read the 16 oz part. What gives?

No, you can't. Mine split when I froze them and I left plenty if room for expansion. This is my only peeve about these otherwise great bottles.
