The increase in the number of people cooking and trying recipes during the pandemic has led to a surge in canning — because experienced canners are doing it more and novices want to give it a try.
And that surge has led to a shortage in Mason jars and lids.
“There’s so many more people canning this year than have ever canned. We have seen a big upswing in new people trying to can,” said Nellie Oehler, the coordinator for Oregon’s statewide food preservation hotline, who added she’s been answering lots of calls from around the nation about the lack of supply.
Marie Bregg, the owner of Mason Jar Merchant, a canning jar supplier, said she started seeing a huge increase in demand in the middle of August.
“Our sales basically went up 600% that week and haven’t dropped since,” she said.
Most of the demand is for the two-part lids necessary for canning, because they are single-use, whereas the glass jars can be used over and over. The lids have a disc that sits on the mouth of the jar with a ring that screws on around it, but after one use, the seal around the disc breaks down and can’t safely be used again.
The reasons behind the shortage
Bregg and Oehler said they attribute the demand to the amount of extra time people had at home since the pandemic started. And people who haven’t canned very much, or at all, are getting in on the trend.
“I call it ‘Sourdough 2.0’ — it was the next craze of what people are doing in the kitchen because they have extra time,” Bregg said. Back in the spring, baking sourdough bread was all the rage
