It used to be that Weck jars were precious things, hard to come by outside of Germany. Then people started discovering how pretty and useful they are. Suddenly, stores from Crate & Barrel to Williams-Sonoma and beyond began stocking them.
No explanation is needed when it comes to storing dry goods in Weck jars, but when it comes to the actual act of canning in them, newcomers sometimes need a little help. A couple years ago, I wrote a step-by-step guide to using Weck jars, and while I have no intention of reinventing that particular wheel today, I do want to pluck out a few of the most commonly asked questions about canning in Weck jars and highlight them here so that they’re easy to access.
How do you tell if Weck jars are sealed? You can tell that Weck jars are sealed because the little tab on the rubber seal will point downwards. You can also test your seal in much the same way that you do with Ball jars. Once the jars are cool, remove the clips and grasp the lid of the jar. Lift off the counter an inch or two. If the seal holds fast, you’re golden. If it starts to lose its seal or breaks the suction entirely, that’s a jar that needs to be refrigerated.
Can you reuse the rubber seal? In all printed materials available in the US, they don’t recommend that you use the rubber seal for Weck jars more than once. However, I’ve been told the instructions printed in other countries tell you that it is reusable until it is stretched out or begins to lose its elasticity. Because I don’t like to take chances, I replace the rubber seal with each use.
Can you pressure can in Weck jars? I have not tried it personally, but I was told that it can be done, provided you add a third clip to the lid, in order to help prevent siphoning during processing.
Is it possible to buy replacement clips? It is! You can actually easily buy replacement clips, rubber rings and even lids for Weck jars. MightyNest, sponsor of today’s giveaway sells all the replacement parts in their canning section.
Because Weck jars are quite a bit more expensive than traditional mason jars, I tend to save them for my favorite preserves. These are the recipes that I like so much that I tend to either keep them all for myself or share them with only those people who are truly deserving.
Plum jam is one of my most beloved preserves, because its flavor reminds me of the rummy jam my mom used to make with the fruit from our backyard trees, in Southern California, when I was very young.
For this jam, I combined 5 cups of chopped plums (a mixture of yellow and red) with 2 1/2 cups of sugar. Once the juices started to run, I cooked the fruit and sugar over high heat until the fruit broke down and the syrup thickened enough to hang off the spatula in little pink windows. A squeeze of lemon juice went in at the end for balance. Processed for ten minutes in an array of Weck jars, this is one preserve I’ll be rationing this winter, to ensure it lasts until plum season returns.
If you’ve been contemplating adding some Weck jars to your kitchen, you’re going to love today’s giveaway.

I would love to replace all my baking pans with the new style that comes with the reusuable cover…no more foil covering.
I want to have more BPA-free storage containers for bringing lunch to work with me or storing leftovers.
I would love to add more glass storage to my kitchen.
Like most people, I’m trying to use more glass instead of plastic. I canned for the first time this year using Weck jars. They are a little tricky, but I really liked them. I would love to own more. It’s too bad that Ball still uses BPA in their lids. Booo.
I would like to continue to convert everything to glass, and use less (commercially) canned items
I would get rid of every plastic storage container I have! It’s taking too long to slowly replace them but I can’t afford to do it all at once.
Switching my pots to cast iron and getting rid of all the plastic.
I would like to use a toaster oven instead of a microwave. I would definitely like to replace all my plastic containers with BPA free products, preferrably glass! I would also like to replace my cookware with cast iron or stainless steal.
Trio Stainless Steel Food Container is a perfect addition. What a great web site….it’s hard to select.
Completely getting rid of plastic used for bringing home items from the bulk bins, and stop using freezer bags.
I use fabric, washable bar towels instead of paper towels whenever possible. I think they are more eco friendly making less trash,etc. I wash them with bleach but I worry a bit about germs. Still in a quandry. Amazing give away.
Getting rid of ALL plastic. I’m doing it sloooowly. My family appreciates it since it means that there are things they can buy me on christmas and birthdays.
I would love to replace all of my plastic containers that I tend to use for my kids’ school lunches. I like glass but they can get a bit heavy for a 7 year old to carry. A cast iron or stainless steel wok would also be a great addition to the kitchen.
a place or a way to stash my pots and pans without them getting bashed
To make my kitchen a healthier place, I’d rebuild the whole thing and include space for a small glass-fronted refrigerator specifically to hold fresh vegetables so that they don’t get pushed to the back of the vegetable drawers and lost until they go bad.
I would love to get rid of all my plastic gladware/tupperware and use only glass. We are slowly getting there!
I would like more reusable items. I know there are canning lids that are reusable. I am slowly getting a stock pile of some but it will be a while before I am finished. 😀
I want to get a good set of stainless steal cookware to replace my hodge podge of hand me down pots and pans.
I’m slowly (as I can afford) replacing my non-stick pans with le creuset enameled ones. Just keep looking in thrift stores and occasionally super on sale at bed/bath/beyond.
I would love reusable sandwich bags!
I have switched over most of my non-stick cookware and plastic tupperware to sturdier, healthier pieces, but there are still a few lingering Calphalon pots and pans that I turn to as back-ups I would still like to replace.
The one change I would make is buy more cast iron and stoneware cookware!
My favorite is my mother’s recipe for Prune Relish which I put into Weck Mini Mold Jars. It’s a great size for giving away as well as opening as a condiment with meats, cheese, etc.
I have been meaning to get reusable snack bags (maybe with “manly” patterns on them so my husband will use them…) and also find additional environmentally friendly cleaning products that work well for me. Love the Weck jars!
I would love to have more glass in which I can microwave leftovers. I always end up microwaving in plastic,…and even though it is BPA free I feel like the glass would produce a more evenly heated food that I would feel better about.
we got rid of our microwave a while ago and heat up our food in a more nature way. I would like to invest more in posh enamelware… and I love adding that fun splash of color to the kitchen.
I would love to eliminate as much BPA as possible from my kitchen. Slowly working my way towards that goal!
Eat less sugar.
I really would like to get rid of ALL the plastic in my kitchen.
I would definitely replace my non stick cookware. The non stick coating is starting to scrape off, and that just can’t be healthy! I would also replace my plastic storage containers with glass.
Getting all the plastic out of my kitchen would be a dream come true. I already use a lot of vintage bail jars for dry goods storage; but it seems like the plastic food storage contaners for the refrigerator or freezer just keeps lingering despite my attempts to get rid of it by sending leftovers home with everyone!
I would like to stop using so many quart yogurt containers to freeze soups and stocks in. I’d rather use all glass! I use glass jars and containers in all other ways but the yogurt containers are so easy and abundant!
I’d like to use less toxic cleaning agents.
I need leftover boxes that can go in the dishwasher! Easier to clean and much sturdier, plus no BPA.
A dishwasher that would get everything steamy sparkly clean…and more vintage Pyrex for leftovers!
I would replace most of my nonstick pans…some of mine are losing their finish, and using a stainless, enamel, or cast iron pot/pan just seems better.
I too am phasing out all the plastics in my kitchen.
I’d like another huge stockpot with a thick bottom.. I make my own broth, and I’d like more room for doing it!
Definitely eliminate all plastic/BPA containers and start over with some really good glass storage.
We’ve been slowly making changes in the kitchen. No more Ziplocs around here! I would love a nice big cast iron pan and lunch box items.
OOH they have stainless steel dinnerware! We have been looking for those. And those jars are just beautiful!
I need to get a smaller size cast iron because my big one is great but not practical for everything. I love cast iron because it heats so evenly and doesn’t wear out like other pans.
I would love to learn how to use cast iron. I use stainless steel, but I know how wonderful cast iron can be… I’m just afraid.
I would love a new, higher efficient refrigerator, but in the meantime I have started buying items in bulk, and using mason jars to store the items in the cupboard. I have also either replaced or stopped buying items that come in plastic.
I would love to replace all my plastic storage with glass, even though what i use is mostly bpa-free…
If I could change one thing, I’d get rid of all my plastic kitchenware all at once…I’m slowly transitioning, but it can’t come fast enough!
I’d love to get some reusable sandwich bags–I’m using containers for everything right now, but they take up so much space in my lunch bag, I’d love to have some bags to put things in!
I’d like to find suitable replacements for the last two non-stick pans in my cabinet. I use them mainly for cooking scrambled eggs and am spoiled by the easy clean-up and no waste factor.
i want a chest freezer so badly so that i can buy large quantities of grass-fed meat.
We’ve done quite a few things to make our kitchen healthier and more environmentally friendly over the last few years. The one piece that is still missing- I would like to get rid of the rest of my plastic Tupperware containers and switch to exclusively glass. All these Weck jars would be a beautiful step in the right direction!
I would replace all my plastic storage containers with glass. I am slowly but surely doing this…I never like to heat anything up in plastic in the microwave so it would be nice to never have to move leftovers into another container when reheating.
I’d like to replace my teflon fry pan with a cast iron skillet. The pans Mighty Nest has are beautiful. I might have just found my Christmas present…
I have been trying to get rid of all of my plastic containers and move to all glass, but it is a slow process!
I’d get a juicer to make my kitchen healthier!
I would like to get rid of the last plastic tupperware containers still kicking around my kitchen for lack of better storage solutions. I would also like to improve my compost efficiency. I think a better container that kept out pests and wasn’t a pain to clean would help me to throw less food scraps away.
I got rid fo the non-stick, now I want stone bake ware!
Like many others who have posted comments, I’d like to get rid of all my plastic food storage containers and get more glass storage containers. It’s annoying to me that most of the glass storage containers have plastic lids. I’d like it if Weck made larger, flatter containers with glass lids that could be clipped for refrigeration, so I needn’t worry about the lid flying off.
my little girls love drinking out of disposable straws, and it has become a guilty pleasure in our house.
LOVE this give away! thanks to the sponsors!
I need to stop using plastic bags. I’m slowly getting a collection of reusable bags that work well for snacks and sandwiches, but I always need more with a busy, hungry toddler.
And I also would really like to never can with the lids with BPA again. It will be an expensive switch to Weck jars, though.
I would switch all my packaging for storage to glass. We’re on our way, but finding the ‘perfect’ container for all our basic items has proved a little difficult, MightyNest looks like a good place to start.
Cutting boards. Haven’t found the perfect solution to keep the boards sanitized, the knives sharp, and the landfill free of worn and nicked boards. I’ve heard that using wood the old-fashioned way is the way to go…with the sanitizing, sanding and oiling.
What an amazing give away! I would LOVE to get rid of all the dangerous plastics in my kitchen. I’ve started storing spices in glass, and canning had brought me many mason jars, but there are still many things that are plastic to get rid of!
I still have a few pieces of non-stick cookware that need to be replaced with cast iron or something.
I have been trying to “go green” with baby steps but I still have room for improvement in the kitchen. Besides the good comments regarding eliminating plastics, which I agree with, I would like to find safer disenfectants, especially for my cutting boards and sink!
I want some new great knives that really cut stuff. I’d like pans without teflon. I’d like to never use plastic again. sigh
I am transitioning out of plastic and into glass for storage… almost done with moving from non-stick to cast iron or stainless steel.
Lets face it, while I live in the most organic state in the US the fact of it is no matter how fresh or local it may be they are putting it in awful containers. Have you ever tasted baby food? Gerber, please that mushy stuff in a chemical jar labeled as bananas tastes nothing of the sort,…..a change I’d like to make is to jam, spread, mash and concoct my own religion of baby food using trusted jars that I know is safe, healthy and free of BPA. Tainted jars, cans and lord help me, those things we call pre-packaged food bags are destroying families one person at a time. I love knowing Weck is everything opposite of that and fighting to protect our families and inform us 🙂 Grow, eat, plant, can your own! Know the risk if you don’t!
I need a bigger fridge. That & a good set of cast iron. I cook A LOT. My family eats mostly fresh or frozen so our fridge space is generally minimal. 🙂 I have stainless pots & pans, but wanna get away from using fats to cook with.
I’d like to stop microwaving in plastic – change to glass only. thanks for being considered
i’d like to switch to cloth napkins.
I now have my eye on the Scrap Happy Scrap Collector & Freezer Compost Bin. We use a compost bucket regularly, but that bin would make things SO much nicer, especially in the summer!
I’ve just started canning and would love to try out Weck jars.
Other than that, I would love love love to have a dutch oven, but can’t really afford one right now.
I just got married, and my kitchen is so lovingly stocked that I can’t even believe that I’d think of adding something to it, but canning jars that will get me into putting up all of the lovely fruit that we see here in San Francisco would be a great addition. And no bpa, right? Bonus!
I’d love to get the rest of the plastic containers out of the kitchen, but DH doesn’t like the glass storage ones, so I guess I’ll have to settle for “doing as much as we can.”
Here’s two for me: I’ve phased out almost all of my plastic tupperware stuff and I’m in the beginning phase of getting rid of teflon coated cookware.
I’m all about growing, cooking and preserving fresh food, so the healthier I can do all of that, the better! I could really use all of the tools on the Mighty Nest site, but I am especially coveting the Weck jars because I’m just learning to can so we can eat fresh year-round – and they are beautiful. I would also love a food mill to help with the canning process and a real compost bin since I use an old coffee can that is neither attractive nor fragrant (love the freezer one – great idea!).
I’d love to find a lightweight non-stick alternative to Teflon – cooking on cast iron is a mystery to me, and too heavy to handle easily!
I want to stop using plastic, both containers and sandwich bags. I’d like to get some nice glass containers. Not sure what to do about packing lunches.
I’d love to get rid of all my plastic items and replace them with glass, wood and stainless steel!
I’ve been working hard to decrease my ziploc/plastic bag use, and reuse the ones I have. Basically, trying to use more reusable mesh produce bags and tupperware in the fridge/freezer!
For me, canning was step one. Step two? Get rid of the plastic storage containers and upgrade to glass.
I want to change my 1 qt pot from non-stick over to regular stainless (non coated) steel. I use it often and want to get away from using anything coated. I wish i could find a smaller cast iron 1qt pan….i would use that instead!
I’d love to switch to an organic mattress. I also am tempted by their salt pig, even though I do already have non-toxic glass containers for my range-side salt pinches!
I usually cook in cast iron skillets, or my favorite Staub enameled cast iron pot, but I am really interested in trying to cook in ceramic. I just learned about that on the Mighty Nest website, and I am feeling curious about it! Thanks for the info!
Kitchenware is sexy!
For me and my family, transitioning to reusable items such as ‘glass straws’ seems like an easy way to stop creating so much waste via discarded straws (not to mention the lack of clear BPA-free labeling on so many straws).
I’d love to replace my non-stick pans… especially since we don’t use them anymore because they started flaking off into our food. Yuck!
I’m with a lot of people, I’d like to get rid of a lot of my plastic storage-ware and replace it with glass. As I’m currently unemployed, I can’t go buying a lot of glassware all at once, but when my grocery budget has a little extra money, I buy one or two pieces at a time.
I need the stainless steal food containers by lunchbot. Packing lunch is hard enough and having convinient healthy containers would remove part of the burden!!
Agree with several of the above posters — reducing plastic use. I haven’t found a great replacement for saran wrap, and several of my containers, despite being glass, have plastic in them. I try to reuse my plastic containers for freezing things in (never heating), but hope to slowly transition over to non-plastic alternatives as I can.
Also reducing paper usage. Right now I mostly use cloth “unpaper” towels, but I can’t get my boyfriend to make the switch as well. I have some silpat mats to replace baking parchment in some cases, but I don’t have mats for all the things I do… so maybe I should learn to switch over to oil-and-flour, instead?
We’ve managed to avoid teflon, and I’m loving my cast iron. 🙂
I’d like to get rid of all my Teflon-coated cookware and just put a little more effort into cleaning!
Always looking for more glass storage and cast iron in this house! Plus I’ve been working with a seriously awkward pot, so that one would be fantastic.
I would really like to replace all of my non-stick frying pans – I’ve been giving my family hints for my September birthday. =)
I’ve already switched from regular cleaning products to vinegar and water – so much easier, cheaper, just as effective, and you don’t have to worry about spraying on food surfaces! Now I’m slowly throwing away plastic in favor of glass for storage, and next I’d like to start buying bamboo instead of wood.
I would really like to get away from plastic in my kitchen. I am slowly replacing all the plastic storage items I have with glass. Unfortunately it is so expensive, but I am working on it as I can!
It is hard to stop reusing plastic containers like yogurt and take out. I use them to freeze soups and beans and the such. I would love to master the art of pressure canning so I can put those items up in a glass jar and not in a plastic container that is leaking it’s harmful chemicals into my food, and by proxy into my and my families bodies.
Only one…I could use about a dozen new items. New pans, bamboo utensils, glass storage. Very cool stuff at Mighty Nest.
I’d like to be free of plastic containers. They clearly have their uses, but if I could afford glass I would make the switch.
I would love to be able to vacuum seal items in jars or bags to help save produce from going bad. This would definitely increase my vegetable intake and also save money!
I would change every thing to cast iron. I have one skillet. I need some pots.
I would solve the ant problem. I am not sure which is grosser/more unhealthy: having the ants or spraying for the ants
