Weck Jar FAQ and MightyNest Giveaway

plum jam

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.

    I would like an alternative to the plastic Tupperware I store so much of my food in. I know it’s better not to re-heat food in them, but I never remember to use a glass container.

    I have started reducing the use of plastics, so glass containers are a must and even better if they allow me to keep seasonal goods all year long 🙂

    My daughter Katie and I are trying to eat healthier, real food (not processed.)

(PS Mighty Nest Rocks!)

    What an awesome give-away. I’m working on phasing out plastics. I have a few glass containers I use for reheating leftovers, but we still store way too much of our stuff in plastic so I need more storage options. And I should really get away from ziplock for sandwiches.

    I’ve recently switched to using all glass containers for leftovers and I’d like to start using something other than plastic containers to freeze extra portions. I’m having a baby soon and am trying to freeze as much as possible right now!

    I definitely need to change over my pots and pans. I have been using the same stuff for 39 years that I have been married. I already have changed over plastic food containers to glass and only use glass for drinking and glass dishes for eating. Learned alot on MightyNest website…..great website by the way!

    I would like to replace the sauce pans that I have with ones that don’t have a non-stick coating. I have already replaced most of the plastics with glass and I love to can. Weck jars were be an amazing addition!

    Angie says:

    I’d love to continue to swap out all my little boys’ plastic plates, bowls and cups with glass. It’s a slow process and there’s been a few mishaps with some of the new glass cups, but it feels so much better to be ridding ourselves of the plastic!

    I only learned to can three years ago, but it has changed how I eat and how I view food. The next step for me is getting rid of the BPA in the traditional canning lids. I’d love some Weck jars!

    We use stainless steel or cast iron for cooking. No aluminum or scratched up tephalon pots and pans. We also switched to glass water bottles instead of the plastic ones. We also try to make more food homemade and eat less store bought/processed foods and we eat mostly organic foods.

    I’m building a compost pile from kitchen waste. The compost will fertilize the food I eat, which I’ll can in some pretty Weck jars. Then I’ll put the waste in the compost pile. I feel like this could be some kind of kids cyclical song. 🙂

    I’ve just sold my boyfriend on bringing his lunch in canning jars (he had so much fun with it!), one step of several in getting the plastic and nonstick cookware out of our kitchen. Someday I would also like to pressure can my own beans and soup, but for now, in addition to getting me over the hump and into regular canning, these lovely jars would make good homes for fridge storage.

    Linda Hoppa says:

    We are antique collectors/dealers, both farm raised, so I have found it easy to go back to the old ways and vintage kitchen ware. We use many of our finds in the kitchen such as old glass containers with glass covers similar to those featured in Mighty Nest article, “12 Ways to Do Away with Toxins in the Kitchen”; granite ware (as long as it is not chipped or cracked); cast iron ware (the only ware I use when frying); crocks for fermentation; wooden utensils for cooling; etc. This year I am making it a goal to stock a winter larder with as much locally grown and home grown canned food as possible in addition to dehydrating fruit for use in the AM oatmeal and baking. In addition to antiquing, I am a avid thrift store browser. Came across a great kitchen buy in our local thrift store in the Spring — over 12 varying sizes of glass storage jars with rubber seals for $3. These are great for storing dehydrated food, spice rubs, honey, etc. but cannot be used to can. Thanks for this great post and the direction to Mighty Nest website. The number one change I would like to make in my canning and kitchen would be to have the opportunity to purchase and use resuable canning lids. I think the Weck jars would be just up my alley.

    Awesome giveaway. I have one weck jar that I love and would really like to add more to my jar supply. A change I would like to make to my kitchenwares is to save more leftovers in glass containers instead of plastic.

    Sheila says:

    I’ve been trying to save glass jars from things i buy at the store like salsa or pickles, but I can never get the smell put of the lid. I’d love to start making and storing my own salsa, pickles, and more. These jars would give me a start and inspiration.

    I’ve been dying to try out Weck jars! While we’ve made a lot of progress switching out the plastic in our home for safer options, we still use ziplock bags for quick storage and transport. Though we wash and re-use them ( now I’m wondering if this is a good idea) and never microwave in them or anything like that, I’d like to explore some better options.

    PepperReed says:

    I would say the chiller pitcher with glass lid would be a great item to add to my kitchen. I have a few plastic pitchers that I sometimes use when we have groups over (and I also reuse juice jugs), but I’m trying to rid our house of all plastic (BPA friendly or not) so having a Lidded (important!) glass beverage container would be very useful.

    I currently work for a farm and help to run one of their stands in Baltimore, Maryland. My goal this summer is to freeze and can enough produce and meat that I only have to go to the store through the winter to get milk and eggs! I love knowing where my food comes from and supporting the wonderful people who provided it for me!

    We recently moved into a house on 5 acres and I am planning an extensive organic garden. Canning will be a critical part of preserving the hoped-for bounty. Although I became a Weck jar fan when we lived in Germany, I have never actually used them for canning. Having the whole set-up would be fantastic!
