Soft caramels keep for weeks, not months: they turn grainy as the sugar recrystallizes, they go sticky in a humid room or hard in a dry one, and the butter and cream slowly go stale. Each caramel wrapped in waxed paper or cellophane, then sealed in a bag or box, keeps much longer than a tray of caramels sitting open. In the example below, a Washington candy maker's wrapped caramels passed every test through day 56, and the bags say best by 42 days, a 25% margin. Below is what ends a caramel's shelf life, how storage changes it, the study, the date on the label, and a free template.
The short version
- Caramels turn grainy, go sticky or hard, and their butter goes stale.
- Wrap each caramel, then seal the bag or box.
- Cook to temperature; corn syrup helps against graininess.
- Freeze sealed caramels for longer storage.
- Run a real-time study and leave a margin before the date.
- The date is a best-by: quality, not safety.
- TaroStack gives every batch its date from the shelf life you set. More below.
What ends its shelf life
| What ends it | What happens | What slows it |
|---|---|---|
| Graininess | Sugar recrystallizes; the caramel turns sandy | Cook to temperature; corn syrup; don't stir while it cools |
| Stickiness | Takes up moisture in humid air | Wrap each piece; sealed bags |
| Hardening | Loses moisture in dry air | Wrap each piece; sealed bags |
| Stale butter and cream | Flavor flattens | Fresh dairy; cool storage |

How it's stored
| Stored | In the example's tests | On the label |
|---|---|---|
| Twist-wrapped, sealed bag, room temperature | Passed every test through day 56 | Best by 6 weeks |
| Twist-wrapped, sealed and frozen | Passed after 3 months frozen and 4 weeks thawed | "Freeze for longer storage" |
| Unwrapped on a market tray | Sticky by the end of a humid day | Wrapped before the market, not after |
Thaw frozen caramels in their sealed bag, so moisture condenses on the bag and not on the candy.
An example: a shelf life study
Columbia Orchard Kitchen, the made-up cottage food maker in Wenatchee, Washington, I use in these examples, twist-wrapped salted caramels from one batch, sealed them in bags, kept them on a shelf at room temperature, and opened a bag at each pull:
| Test | Pass if | Day 0 | Day 14 | Day 28 | Day 42 | Day 56 | Day 84 |
|---|---|---|---|---|---|---|---|
| Texture score, 1 to 9 | at least 6 | 9 | 9 | 8 | 7 | 6 | 5 |
| Taste score, 1 to 9 | at least 6 | 9 | 9 | 8 | 8 | 7 | 6 |
| Graininess, 1 to 5 | at most 2 | 1 | 1 | 1 | 1 | 2 | 3 |
| Stickiness, 1 to 5 | at most 2 | 1 | 1 | 1 | 2 | 2 | 3 |
| All pass? | Pass | Pass | Pass | Pass | Pass | Fail |
Everything passed through day 56; at day 84 the texture fell below 6 and the caramels were grainy and sticky. Taking a 25% margin off day 56 gives 42 days, six weeks. How the pulls and margin are planned is in shelf life testing. The cottage food rules the kitchen works under are in washington cottage food laws.
The date on the label
A caramel's date is a quality date: "Best by" or "Best if used by". In California, food made from July 1, 2026 that shows a date uses "BEST if Used by" for quality, in sell by date law, and how to write the date is in best by date format.
Get the template
Download the caramel shelf life study template. One sheet: the product, the lot tested, the day it was made, how it's stored and the margin to leave; then each test with its limit and the result at each pull. It marks each pull pass or fail, finds the last day everything passed, takes the margin off, and gives the shelf life for the label and the date for a batch made today. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.
Where this stops working
The study gives one date for one caramel. Salted, vanilla and apple cider caramels, batches every week, bags at two markets and on the website: someone has to date each batch and sell the oldest bags first.
How TaroStack does it
TaroStack gives every batch its date from the shelf life you set, and sends the oldest out first.
Dates from the shelf life. Each caramel carries its shelf life in days, and each batch's lot gets its production date and the date that follows from it.
First-expired-first-out. Orders take the oldest lots first by default, and a shop can be set to take only stock with enough days left.
What's coming up. A forecast shows what will expire unsold and what it costs, and anything thrown out is recorded with its reason, expired or spoiled, so waste shows by item.
| The job | Spreadsheet | In TaroStack |
|---|---|---|
| The date on a batch | Worked out by hand | From the shelf life, on the lot |
| Which batch goes out first | Dates on tape | First-expired-first-out |
| Stock with enough days for a shop | Checked by hand | The customer's shelf-life rule |
| What expired last month | Not counted | Waste by reason |
Lots, dates, first-expired-first-out and the expiry forecast are on every plan, from $49 a month. The first 30 days are free, with no credit card. If you'd like a hand setting up, ask, and we'll do it with you.
