Canning in Vintage Jars

DSC_0087

When I first started becoming truly enthralled with canning, I began to look beyond the standard Mason/Ball/Kerr jars available. I discovered the Weck jars that are typically used in Europe, but was put off a bit by the price tag and the fact that they are often hard to actually get (I did break down and order a half dozen from Lehman’s, but with shipping, they cost somewhere in the neighborhood of $7 a jar. That is far too much for the volume of canning I typically do).

However, when I took a close look at the way in which the Weck jars seal, I realized that they are practically identical to the vintage bailing wire canning jars that were popular in this country through most of the 20th century. The glass lids on the Weck jars seal via a rubber gasket. Through the hot water process, everything is held in place by a couple of metal clips. The glass lids on the vintage jars seal via a rubber gasket.

During canning, the lid is held in place by the metal wire that locks up over the lid. The thing that makes the vintage jars even better than the Weck jars is that you have an easy way to keep the jar closed after you’ve opened it, via the bailing wire. When you use the Weck jars, you have to keep replacing the metal clips (or get a set of their plastic lids).

So once I figured out that the jars I already had (and had gotten for free when helping a friend of a friend clean out her mother’s basement) would do the exact same job as the spendy ones, I got down to work. I ordered a set of rubber gaskets from Lehman’s for just over three bucks (they’re the only ones who still seem to carry them) and made a canning plan.

I did a mixed berry jam, because I’ve been endeavoring to clean out my freezer, in preparation for the coming onslaught of produce and still had some frozen fruit from last summer. I supplemented my frozen strawberries and raspberries with some fresh (but cheap and decidedly not local) strawberries (I made up for it the following week by hand-picking 13 pounds of local strawberries and making the best jam I’ve ever tasted. That recipe is coming later this week).

When canning with these jars, most of the steps are the same as with the screw-top jars. You clean your jars, lids and seals well, prepare your jam and fill the jars. Once the jars are filled, you wipe the tops clean and the apply the rubber seals and top with the glass lids (of course, making sure that your vintage jars and lids are without chips, cracks or other damage).

Like when you can with conventional mason jars, you need to leave some space for the air to escape. To do this, you don’t lock the wire down all the way. You close it so that it’s closed, but pointing up, not down (if this doesn’t make sense, just get an old bailing wire jar and start opening and closing it. You’ll soon notice the two closure positions).

Process jars as usual. When time has elapsed, remove the jars from the water, being careful not to tip them (these jars are mostly glass, which means that if you get the jam on the top of the lid, you’ll see it, and if you’re a bit of a perfectionist, the residue that will stick to the lid will vex you). At this point, grab a tea towel and lock the wires into the tightest position with the wire pointed downwards. This presses the rubber gasket more firmly into contact with the rim of the jar and ensures a good seal.

These jars are in the fully locked, post-process position.

The next day, when the jars are all cool, unlock the bailing wire. The lid should not move in the slightest. Test your seal by picking the jar up by the glass lid (don’t go crazy, just lift an inch or two above the countertop). It should hold fast. If it doesn’t, your seal is no good. If it holds, leave the wire unlocked and store as you would any other sealed jar.

Mixed Berry Jam

Yield: Makes 3 1/2 to 4 pints

Ingredients

  • 8 cups chopped mixed berries (if frozen, let defrost thoroughly) with their juice
  • 5 cups sugar
  • 1 vanilla bean, split and scraped
  • 2 lemons, zested and juiced
  • 2 packets liquid pectin

Instructions

  1. Pour the fruit into a large, wide pot (give yourself at least 8-9 quarts). Add sugar, vanilla bean seeds and vanilla been pod and stir to combine.
  2. Once, the sugar has begun to dissolve, set the pot over high heat and bring to boil. Once it reaches a boil, reduce the heat to medium-high and cook at a gentle bubble for 15-20 minutes, until the jam begins to look syrupy.
  3. Bring up to a rolling boil and add the lemon juice, zest and pectin. Let boil for an additional five minutes and check the set with either the saucer test or the sheet test.
  4. Ladle into prepared jars, clean rims, apply lids and process in a hot water bath for 10 minutes (remember that you don't start timing until the water has reached a boil).

    Hi there, I was fortunate to come across a few old ball jars with the attached glass lids ($2 each!!). However they have been stored for years closed with the rubber seal compressed on there. It is stuck. Short of chipping it off, do you have any advice?

    I agree and can see no difference other than price of these vs the Weck. They both have lids, gaskets and ring/wire bale. You remove the ring of the Weck and loosen the bale both can be watched and tested for a bad seal. I see no safety issues at all and intend to use mine.

    Hi, I have a bunch of vintage ball jars… a few dozen. I am planning on replacing the rubber gaskets through the same seller. But, what am I to do about the rusty wires? I cannot seem to find replacements anywhere! Can you help?

      You just can’t get new wires. You can either pull them off the jars and scrub them, or you can just live with them. They don’t come into contact with the food, so they won’t impact the safety of your food.

    I’ve acquired some Crown jars and bought new rubber seals, but I’m not having much success in getting the jars to seal. I’m keeping the mouths of the jars clean and the rubber seals are clean and so are the glass tops. Is there something I’m missing? Should I be tightening the screw band after removing the jars from the hot water?

    I am new to canning and am curious about the following jars I found.
    I think they are adorable and want to preserve some apple butter in them to give as Christmas gifts. Could you please let me know if I could use your same method as described in this post if I were to use these jars? They are clamp top, so I’m not sure if they’re meant for canning.

    Thank you so much! Your blog is adorable and so helpful!

      Those jars may not be rated for boiling water bath canning. You’d need to check with the manufacturer before you try canning in them.
