Wine and Liquor

Speaking of drinks, most types of distilled spirits, which include vodka, rum, tequila, and others, won’t spoil - even after they’ve been opened. Bottles of wine will last indefinitely as long as they remain unopened, but their flavor and color will change over time. You should store your spirits and wine in a cool, dark area, away from direct heat or sunlight, and keep bottles tightly closed when not in use to maximize freshness.

Sugar

Like its counterpart, honey, sugar doesn’t have the characteristics to create an environment in which bacteria will thrive. Sugar is also hygroscopic, meaning that molds or bacteria will not thrive in the powdery sweetener, especially when kept in a sealed, airtight container. Sugar will become hard over time. But both white and brown sugar can be revived by being heated for 30 seconds in the microwave, or you can throw a slice of bread in your sugar container, which has been said to help soften it. Be sure to pull the bread out - because bread will spoil and introduce mold to the container.

Salt

Just like sugar, salt doesn’t have the characteristics that would encourage bacterial growth, meaning that you can keep your salt for a long time, as long as it’s stored properly. To avoid clumping in humid climates, you can add some crackers or uncooked rice to your storage container or salt shaker.

Cornstarch

Cornstarch is another kitchen staple that tends to hang around for a long time. This sauce thickener will keep indefinitely when stored properly - tightly sealed in an airtight container, and stored in a cool, dry area of the kitchen, away from direct heat.
