Hello, I'm a baking enthusiast and I've been working with sugars for many years. You asked about how long you can keep brown sugar. Let's dive into that!

The shelf life of brown sugar depends on a few factors:

* Type of Brown Sugar: Light brown sugar, with its lower molasses content, tends to last longer than dark brown sugar, which has a higher molasses content. Molasses, being a natural humectant, attracts moisture and can contribute to spoilage.
* Storage Method: How you store your brown sugar is crucial.
* Airtight Container: This is the best way to keep brown sugar fresh. You can use a glass jar, a plastic container, or even a reusable zip-top bag. Ensure the container is airtight to prevent moisture and air from affecting the sugar.
* Refrigerator: For long-term storage, brown sugar can be kept in the refrigerator. This helps to slow down the hardening process.
* Moisture Levels: Brown sugar is hygroscopic, meaning it readily absorbs moisture from the air. In humid environments, it can harden faster, whereas in dry climates, it tends to last longer.

**How to tell if brown sugar is still good:**

* Appearance: Brown sugar that is still good should have a consistent color and texture. If it's hard, clumpy, or has changed color, it might be past its prime.
* Smell: Fresh brown sugar has a sweet and slightly molasses-like aroma. If it has a sour or stale smell, it's likely spoiled.
* Taste: A simple taste test is the best way to determine if your brown sugar is still good. If it tastes bitter or sour, discard it.

General Guidelines for Shelf Life:

* Unopened:
* Light brown sugar: Up to 1 year in a cool, dark pantry.
* Dark brown sugar: Up to 6 months in a cool, dark pantry.
* Opened:
* Light brown sugar: Up to 3 months in an airtight container at room temperature or up to 6 months in the refrigerator.
* Dark brown sugar: Up to 2 months in an airtight container at room temperature or up to 4 months in the refrigerator.

Tips to Prevent Hardening:

* **Place a slice of bread or a marshmallow in the container:** These will absorb excess moisture and help prevent the sugar from hardening.
* Microwave for 10-15 seconds: This will soften the sugar. Just be sure to let it cool completely before using it.

**Remember, these are general guidelines, and the actual shelf life of your brown sugar may vary depending on the specific conditions. However, if your brown sugar becomes hard or develops a bad odor, it's best to discard it.**
