I have made a lot of homemade hot sauces recipes. Some of which I did not care to share with others but many that I enjoy with others at gatherings and giving away to people. Homemade hot sauce may not have the same preserving qualities as a commercially made sauce therefore the shelf life may be limited.
In general, an unpasteurized homemade hot sauce stored at room temperature has a shelf life of 1-2 weeks. With proper pasteurization and refrigeration, homemade hot sauce can last 2-3 months. Adding vinegar, salt and sugar as natural preservatives, using dried chilies and bottling in sterilized jars can further extend the shelf life to 6-12 months. The key factors that determine shelf life are ingredients, pH, processing methods and storage conditions. With the right combination of these factors, a properly made homemade hot sauce can last for several months.
The shelf life of a homemade hot sauce depends on several factors:
| Ingredients | Ingredients like vinegar, salt and sugar act as natural preservatives and extend the shelf life. |
| pH level | Hot sauces with a lower pH due to higher acidity will last longer since bacteria have a harder time growing in acidic environments. |
| Pasteurization | Properly pasteurizing the hot sauce by heating it to a high enough temperature will kill bacteria and extend its shelf life. |
| Refrigeration | Storing the hot sauce in the refrigerator at 40°F or below will slow the growth of bacteria and other microorganisms that cause spoilage. |
| Packaging | Using sterilized bottles and jars and sealing them properly will help keep bacteria out and extend the shelf life. |
- Ingredients: Ingredients used to make hot sauce like vinegar, salt and sugar act as natural preservatives and extend the shelf life. Some of these same ingredients can be used in processes like fermentation as well. Oil-based sauces tend to spoil faster because they may not be mixed equally with the preserving ingredients.
- pH level: Hot sauces with a lower pH due to higher acidity will last longer since bacteria have a harder time growing in acidic environments. A hot sauce with pH below 4.6 is considered safe and will not allow harmful bacteria to grow.
- Pasteurization: Properly pasteurizing the hot sauce by heating it to a temperature of 161o Fahrenheit. This will kill bacteria and extend its shelf life for a couple of months. Read more here on How To Pasteurize a Hot Sauce for precise temperatures and durations.
- Refrigeration: Storing the hot sauce in the refrigerator at 40°F or below will slow the growth of bacteria and other microorganisms that cause spoilage no matter what the pH level is. The only negative about refrigeration is the costs associated. Read More…
- Packaging or bottling: Using sterilized bottles and jars and sealing them properly will help keep bacteria out and extend the shelf life. In addition, sealing the bottles with an induction sealer will prevent air from entering a packaged hot sauce.
Extending the shelf life
Here are some methods to increase the shelf life of homemade hot sauce:
| Sterilize equipment | This includes jars, lids, utensils, and any bowls or pots used. Boil them in water or use the dishwasher. This will kill any bacteria that could cause the hot sauce to spoil. |
| Use vinegar | Vinegar is high in acidity which helps preserve the hot sauce and inhibit bacterial growth. |
| Add salt | Salt acts as a preservative and draws moisture out of bacteria, further inhibiting their growth. |
| Cook the sauce | Bring the hot sauce mixture to a boil and let it simmer for 20-30 minutes. |
| Fill BOTTLES hot | Immediately after cooking, fill the sterilized bottles with the hot sauce. The heat will kill any bacteria that may be on the jar rims. |
| Seal the BOTTLES | Use lidded Mason jars and screw the rings on tightly to create an airtight seal. |
| Store in cool dark place | Refrigerate the hot sauce after opening. The cooler temperature will slow bacterial growth. |
- Sterilize all equipment and containers thoroughly: Even just a slight amount of hot sauce can grow unwanted bacteria. Sanitizing includes bottles, jars, lids, utensils, and any bowls or pots used. Boil them in water or use the dishwasher. This will kill any bacteria that could cause the hot sauce to spoil.
- Use vinegar as the base: Common in many well-known hot sauces, vinegar is high in acidity which helps preserve the hot sauce and inhibit bacterial growth. The higher the vinegar content, the longer the shelf life of the hot sauce. Aim for at least 20% to 25% vinegar. Get more details here in The Guide to Making Hot Sauce.
- Add salt: Salt acts as a natural preservative and draws moisture out of bacteria, further inhibiting their growth. Use 1-2 tablespoons of salt per cup of hot sauce but always salt to taste, especially for first time homemade hot sauce recipes. Read more on The Positive and Negative Effects of Salt in a Hot Sauce.
- Cook the hot sauce: Bring the hot sauce mixture to a boil and let it simmer for 20 to 30 minutes. This will kill any bacteria present in the ingredients, but it will also thicken a sauce, change the appearance, alter the flavor, and reduce the spiciness.
- Fill bottles while hot: Immediately after cooking the hot sauce, fill the sterilized bottles with the hot sauce before it cools down completely. The heat will kill any bacteria that may be inside or on the bottle rims. Turn the hot sauce bottle upside down ONCE IT IS CAPPED! This will kill any bacteria on the underside of the cap.
- Seal the bottles tightly: Most woozy bottles should have a seal that is sealed with an induction sealer. If you are going for a homemade approach to your hot sauce, use lidded Mason jars and screw the rings on tightly to create an airtight seal. This prevents bacteria and mold from entering and spoiling the sauce before it gets used.
- Store in a cool, dark place: Refrigerate the hot sauce after opening or store it in a dark cool place. The cooler temperature will slow bacterial growth even if the sauce has been fermented or cooked and sealed properly. A homemade hot sauce is always under risk of not being sealed properly.
How to ensure a hot sauce is safe
Here are some key ways to ensure your hot sauce is safe:
| Use safe ingredients | Make sure all your ingredients, especially produce, are thoroughly washed before use. Avoid using expired, moldy or otherwise questionable ingredients. |
| Properly sanitize equipment | Wash all equipment, utensils, bowls and bottles in hot soapy water and sanitize with a bleach solution or in the dishwasher on the hottest setting. |
| Check the pH level | Use a pH meter or pH test strips to ensure the hot sauce has a pH of 4.6 or lower. Most bacteria cannot survive in such an acidic environment. |
| Add preservatives | Ingredients like vinegar, salt and sugar help prevent bacterial growth. Use enough to ensure the hot sauce has a long shelf life. |
| Properly seal and store containers | Use sterilized bottles and lids, and seal them tightly to prevent contamination. Store in a cool, dark place or in the refrigerator once opened. |
| Monitor for signs of spoilage | Check the hot sauce regularly for changes in color, texture, smell or bubbling that could indicate bacterial growth or spoilage. |
| Get it tested | For the highest level of assurance, have your hot sauce tested by a commercial food testing lab. They can identify any pathogens of concern and ensure it meets safety standards. |
Use safe ingredients. Make sure all your ingredients, especially produce, are thoroughly washed before use. Avoid using expired, moldy or otherwise questionable ingredients.
- Use safe ingredients: Make sure all your ingredients, especially produce, are thoroughly washed before use even if you are cooking a hot sauce. Avoid using expired, moldy or otherwise questionable ingredients because this will shorten the shelf life of hot sauce.
- Properly sanitize equipment and containers: Wash all equipment, utensils, bowls and bottles in hot soapy water and / or sanitize with a bleach solution or in the dishwasher on the hottest setting. Sanitization Tablets work equally as well following the manufacturer’s instructions.
- Pasteurize the hot sauce: Bring the hot sauce to a boil and maintain a rolling boil for at least 2 minutes. This will kill any bacteria that may be present and deter bacteria from growing immediately as you bottle your sauce. You can also pasteurize in a water bath in an oven…get more information on Canning Hot Sauce here.
- Check the pH level: Use a pH meter or pH test strips to ensure the hot sauce has a pH of 4.6 or lower. Testing should be done when the sauce has cooled down to room temperature. Most bacteria cannot survive in such an acidic environment. However, a hot sauce below 2.5 may be too acidic and give the sauce a very pungent flavor.
- Add preservatives: Ingredients like vinegar, salt and sugar help prevent bacterial growth. Use enough to ensure the hot sauce has a long shelf life. Other preservatives are commonly used in hot sauces that are closer to the alkaline side of the pH scale.
- Properly seal and store containers: Use sterilized bottles and lids, and seal them tightly to prevent contamination. Store in a cool, dark place or in the refrigerator once opened. Leaving a hot sauce unopened will create bacteria very quickly.
- Monitor for signs of spoilage: Check the hot sauce regularly for changes in color, texture, smell or bubbling that could indicate bacterial growth or spoilage. Discard all of the sauce immediately if any issues arise. This is a great method of monitoring the shelf life of a new hot sauce recipe.
- Get it tested: For the highest level of assurance, have your hot sauce tested by a commercial food testing lab. They can identify any pathogens of concern and ensure it meets safety standards. Check out some of the labs recommended by Hot Sauce Hell HERE!
With these precautions, you can be confident your homemade hot sauce is safe for consumption and shelf stable.
Oil based hot sauce
Oil-based hot sauces will typically have a shorter shelf life than vinegar-based sauces. The key factors that determine how long oil-based hot sauce lasts are:
| Ingredients | Ingredients like spices, chilies and vegetables all have a limited shelf life, even in oil. Over time they can lose flavor and quality. |
| Acidity | Oil-based hot sauces tend to have a higher pH (lower acidity) which allows bacteria to grow more easily. |
| Pasteurization | If the hot sauce is properly pasteurized by heating it to at least 161°F, this can extend its shelf life significantly. |
| Packaging and storage | Using sterilized bottles and jars, sealing them properly and storing in a cool, dark place helps prevent contamination and slows bacterial growth. |
| Refrigeration | Once opened, oil-based hot sauces should be refrigerated. This slows down the oxidation of the oil and the activity of microorganisms that cause spoilage. |
- Ingredients: Ingredients like spices, chilies and vegetables all have a limited shelf life, even in oil. Over time they can lose flavor and quality, and this can be accelerated when mixed with other ingredients. According to Penn State Extension oil will not preserve ingredients but can help with oxidization.
- Acidity: Oil-based hot sauces tend to have a higher pH which allows bacteria to grow more easily. Oil, like water, will generally have a neutral pH of 7. When mixed with other ingredients this can negate the acidify of a hot sauce. Read HERE for the pH levels of some common hot sauce ingredients.
- Pasteurization: If the hot sauce is properly pasteurized by heating it to at least 161°F, this can extend its shelf life significantly. Temperature higher than this will “cook” the sauce but temperatures below this will not preserve a hot sauce. Get more info on How To Pasteurize a Hot Sauce directly from Hot Sauce Hell.
- Packaging and storage: Using sterilized bottles and jars, sealing them properly and storing in a cool, dark place helps prevent contamination and slows bacterial growth. Refrigeration is the best, but the idea here is to not store them in hot and humid places.
- Refrigeration: Once opened, oil-based hot sauces should be refrigerated. This slows down the oxidation of the oil and the activity of microorganisms that cause spoilage.
With these factors in mind, an unopened and unpasteurized oil-based hot sauce stored at room temperature typically has a shelf life of 1-3 months. With proper pasteurization and refrigeration after opening, an oil-based hot sauce can potentially last 6-12 months. However, the quality and flavor will degrade over time. Some signs the hot sauce has gone bad include:
- Changes in color or consistency
- Excessive bubbling
- Mold growth
- Rancid or “off” smells
If you notice any of these issues, discard the hot sauce. As with any homemade food, it’s important to monitor the hot sauce closely for signs of spoilage and discard it if you have any safety concerns. Hope this helps! Let me know if you have any other questions.
