Labeling (masking tape works fine, ask me about my fancy labels)
Jars are sealed, checked, stored. One last thing — small, but skip it and you'll be standing in the pantry in March holding a jar of brown liquid asking "is this the peaches or the jam I did weird that one time."
Label your jars. That's the lesson. But let me walk you through it, because there's a right amount of effort here and it's less than you think.
What actually needs to be on there
Two things, non-negotiable:
- What it is. Sounds obvious until you've got six jars of amber liquid on a shelf and no memory of which was peach and which was the pickle brine that didn't take.
- The date. Month and year is plenty. You don't need the day. You're not signing a legal document, you're trying to know if this is a jar from this summer or one you found behind the water heater from three summers ago.
If you want to get fancy, add the recipe or a note — "less sugar next time," "good, do this again." Future you will thank present you. Future you always thanks present you for the smallest stuff.
What I actually use
Masking tape and a Sharpie. That's the whole system. Tear off a strip, stick it on the lid or the side of the jar, write the month and year and what's in it. Ten seconds. It's not cute but it works, and it peels off clean when you reuse the jar — which paper labels with adhesive don't, they leave that gummy residue and then you're scrubbing with a fingernail feeling betrayed.
Now — I'll admit I have a drawer. In it are labels I designed myself, printed on nice cardstock, little peach graphic and everything, made a few winters back when I had a slow week and got ambitious. I've used exactly zero of them. Too nice. I look at the jar, I look at the label, and I think "this jam doesn't deserve that," and I grab the masking tape. Ask me about them sometime, I'll show you — sitting in a drawer with some notecards, judging me quietly. This happens to people who get too excited about a hobby. You start canning jam and two years later you own a label maker you use twice a year.
Point is, don't let labeling become its own project. It's supposed to save you time, not eat it.
Where to put it
Lid or shoulder of the jar, not the ring. Rings come off, get swapped, end up on a different jar entirely by the time you look again. Put the label on the ring and you'll open the pantry to find a jar of dill pickles wearing a "peach jam, Aug 2025" ring like a stolen jacket.
I like the lid, because you see it head-on looking down at a shelf, which is how most of us actually look at pantry shelves. Side of the jar works too if your shelves are eye-level.
Why this matters more than it seems like it should
You will not remember. I don't care how confident you are right now with eight jars of one single batch of peach jam in front of you, thinking "obviously I'll know what this is." You won't. Come January you'll have four jams, three kinds of pickles, maybe a batch of salsa if you got ambitious, and they all look the same in a jar under pantry light. This is the most preventable disappointment in the whole hobby. Don't let it happen over something that takes ten seconds.
And the date matters for the same reason we covered in the storage lesson — quality drifts. A jar from thirteen months ago is probably fine. A jar from four years ago is one I'd want to know about before I opened it and took a bite.
I'll say this too, since it fits here as well as anywhere: the fear a lot of people start out with, that their canning is dangerous, is mostly misplaced. Water bath canning is for high-acid food — jams, pickles — and if you followed the recipe and the acid ratios, you're fine. The label isn't there because I think you poisoned yourself. It's there because your memory is bad, mine too, and jars all look the same after a while.
One more thing. My first summer doing this, the very first time a lid sealed on its own on the counter — that little "tink" — I called my sister just to describe the sound to her. Described a noise over the phone like it was breaking news. She did not care, at all. I still think about that call, because I was so proud of a jar making a noise. That's canning. Small stuff feels enormous when it's yours.
Before next time
Grab masking tape and a Sharpie if you don't already have them in the kitchen drawer — that's genuinely all the labeling setup you need. Next time we close out with troubleshooting: what goes wrong, and what it means when it does.
