Sealing Mason Jars With Alcohol: The Right Way

how to seal a mason jar with alcohol in it

There are several methods to seal a mason jar containing alcohol. One common method is the water bath technique, which involves sterilising the jars in boiling water for 10-15 minutes, filling them with alcohol, sealing them, and then boiling them again. This method can also be done using a dishwasher or an oven set to 200-250˚ F. Another option is to use a vacuum sealer machine with a glass jar sealing attachment. Alternatively, you can use a wax sealing method, which involves melting wax in a ceramic dish over a candle and then pouring it into the jar. Sterilising the jars before sealing is important, and this can be done by boiling them in water, running them through a hot dishwasher, or using an oven.

Sterilise the mason jar using boiling water or an oven

Sterilising your mason jar is an important step in preserving your alcohol and should not be omitted. There are several ways to sterilise a mason jar, but not all methods are considered safe. Here is a detailed, step-by-step guide to two of the most common methods: using boiling water and using an oven.

Using Boiling Water:

First, ensure your mason jar is made of tempered glass with a two-piece vacuum cap (a metal screw band and a flat, rubber-lined metal lid). Then, prepare the jar by inspecting it for any defects such as nicks, cracks, or sharp edges. Hand wash the jar and lid in warm, soapy water, and rinse.

Next, fill a large pot with water and place it on a stove burner. The pot should be at least two inches taller than the jar and fitted with a rack and a lid. Place the jar upright in the pot, and fill it with hot (but not boiling) water, ensuring the water level is one inch above the top of the jar. Bring the water to a rolling boil, and then begin timing. The baseline boiling time is 10 minutes, but you may need to adjust depending on your altitude. For every 1,000 feet above sea level, add one additional minute of boiling time.

Once the jars have boiled for the appropriate amount of time, turn off the heat. If you are not yet ready to fill the jar, you can leave it in the hot water for up to one hour. When you are ready to proceed, use jar lifters or tongs to remove the jar from the water, drain it well, and set it aside to dry on a clean surface.

It is important to note that you should not boil the metal lid or ring of the jar, as the extreme heat can damage the rubber sealing rings, resulting in a broken seal. Instead, place the lid and ring in water that is simmering (not boiling) for 10 minutes to thoroughly clean them.

Using an Oven:

While some sources suggest using an oven to sterilise mason jars, it is important to note that this method is not considered safe by food safety authorities and is not recommended. Glass heats unevenly in dry oven air, creating hot and cold spots that can weaken the jar and possibly result in breakage. If you choose to use this method, you do so at your own risk.

To sterilise a mason jar in an oven, first, ensure your oven is clean and free of any contaminants. Then, preheat your oven to 275°F/130°C. Do not heat the oven any higher, as this may cause the glass to break. Arrange the jars on an oven shelf, ensuring they are not touching each other. Place a double layer of newspaper on each shelf, but not on the oven floor, and keep it away from any flames if using a gas oven.

Once the oven has reached the desired temperature, place the jars in the oven and set a timer for a minimum of 20 minutes. When the time is up, use thick oven mitts to remove the jars from the oven, placing them on a heatproof mat or pad.

Again, it is important to note that this method is not recommended due to safety concerns. The boiling water method is a safer and more effective way to sterilise your mason jar.

Prepare the jar by checking for defects and cleaning

To seal a mason jar with alcohol, it is important to prepare the jar by checking for defects and cleaning it thoroughly. Here is a step-by-step guide to preparing your mason jar:

Firstly, carefully inspect the jar and lid for any defects. Look for any nicks, cracks, or sharp and uneven edges, both on the inner and outer layers of the lid and jar. Ensure that the bends fit the jar correctly. If there are any defects, discard the jar and choose another one.

Once you have selected a suitable defect-free jar, it's time to clean it. Wash the jar and lid in warm soapy water, ensuring that you clean both the inner and outer surfaces. You can either hand wash the jar and lid or place them in a dishwasher. If you opt for hand washing, ensure that the jar and lid are thoroughly dried before proceeding to the next step.

Some sources recommend sterilizing the jar before use, especially if the processing time for your recipe is 10 minutes or less. Sterilization can be done by placing the jar in a pot of boiling water for 10-15 minutes. Alternatively, you can use an oven set to 200˚-250˚ F for a similar duration. If you plan to use a boiling water bath or pressure canner for more than 10 minutes, sterilization may not be necessary, as the high temperatures will kill any bacteria.

Before filling the jar with alcohol, ensure that the rim of the jar is clean and dry. This is important to ensure a proper seal. Now your jar is prepared and ready for the next steps in sealing and storing your alcohol!

Fill the jar with alcohol, leaving some space at the top

Filling the jar with alcohol is a crucial step in the sealing process. It is important to leave some space at the top of the jar, as this allows for proper sealing and helps prevent spillage. The amount of space left in the jar can vary depending on the method used for sealing. For example, when using the water bath method, it is essential to ensure that the water covers the jar tops by about an inch or more. This ensures that the contents of the jar are fully submerged and sterilized.

When filling the jar with alcohol, it is important to use a funnel to avoid spillage and ensure a neat finish. It is also recommended to have your desired ingredients prepared beforehand, so you can efficiently fill the jar without delay. For example, if you are infusing alcohol with fruit, it is advisable to have your fruit cleaned, cut, and boiled beforehand, along with any additional ingredients such as sugar and lemon juice. This way, you can quickly fill the jar with the alcohol and the prepared ingredients, creating an efficient production line.

The amount of alcohol you fill the jar with will depend on the size of the jar and the quantity of ingredients you plan to add. It is generally recommended to fill the jar almost to the top, leaving a small amount of space for sealing. This ensures that the alcohol fully covers the ingredients and allows for a secure seal. It is important to note that overfilling the jar may result in spillage or an uneven seal, so it is best to err on the side of caution and leave a little extra space.

While filling the jar, take care to avoid any spillage or mess. It is a good idea to have a clean, dry cloth or paper towel nearby to wipe away any spills or drips immediately. This will help maintain a clean workspace and prevent any sticky residue from forming on the jar or its lid. Remember to handle the jar with care, especially if it contains hot liquids or ingredients, to avoid any burns or accidents.

Once you have filled the jar with alcohol and added your desired ingredients, it is time to secure the lid and seal the jar. Ensure that the rim of the jar is clean and free of any residue or debris before placing the lid. This step is crucial, as any contaminants on the rim can interfere with the seal and compromise the quality of your preserved goods. After placing the lid, you may proceed with your preferred sealing method, such as the water bath method or vacuum sealing.

Seal the jar using a water bath or wax sealing method

Sealing a mason jar using a water bath or wax sealing method is a great way to preserve alcohol. Here is a detailed, step-by-step guide on how to do it:

Water Bath Method:

Firstly, it is important to sterilize your mason jars. Fill a large pot with water and place the jars inside, ensuring they are completely covered with water. Bring the water to a simmer, not a boil, and leave the jars in the hot water until you are ready to use them. This process helps to sterilize the jars and prevent the growth of bacteria.

While the jars are sterilizing, prepare your alcohol or any other foodstuff you wish to preserve. For the water bath method, it is crucial to use naturally acidic foods or add acid to your recipe. This can include fruits, fruit juices, jams, pickles, or chutneys.

Once your jars are sterilized and your recipe is ready, it's time to fill the jars. Leave about a quarter of an inch of space at the mouth of the jar to allow for expansion during processing. Screw on the lids tightly, ensuring the rims are clean.

Now, prepare your water bath canner. Fill it halfway with water and maintain a simmer at 180°F. Place your filled and sealed jars into the canner, ensuring they are covered by one to two inches of water. Bring the water to a rolling boil and process for the time indicated in a tested preserving recipe.

After processing, turn off the heat and remove the lid of the canner. Allow the jars to rest in the canner for about 5 minutes to adjust to the outside temperature. Then, carefully remove the jars using tongs or a jar lifter and place them upright on a towel. Do not tighten the lids as this may interfere with the sealing process.

Let the jars cool undisturbed for 12 to 24 hours. To check if the jar is sealed, inspect the lid. If it is depressed, the jar is sealed. Properly sealed jars can keep goods unspoiled for up to a year.

Wax Sealing Method:

To seal your mason jar with wax, you will need a few supplies: a ceramic wax sealer dish, filament tape, scissors, a tea candle, a kitchen lighter, and bottle sealing wax. Set up your workspace by placing the ceramic wax sealer dish on a table, and if needed, place a small rack underneath to hold a candle.

Light the tea candle and place it under the wax heating dish. Add granular wax to the dish and heat it until it melts, adding more wax until the liquefied wax reaches about 2cm from the top. This process should take around 20 minutes.

Once the wax is melted, blow out the candle. Pour your alcohol into the mason jar and twist the cap on tightly. Wrap the filament tape around the cap, overlapping it slightly, and cut the tape. This tape will help you break the seal when needed.

Now, it's time to dip the jar into the wax. Turn the jar upside down and dip it straight into the melted wax, then lift it out. Spin the jar as you remove it to prevent dripping. At this point, you can optionally press your engraved wax seal into the top of the wax for a personalized touch.

Allow the wax to cool and dry completely before moving your sealed mason jar. The wax sealing method provides an aesthetically pleasing way to seal your mason jar, especially for craft projects or gifts.

Store the sealed jar in a cool, dark place

Once your Mason jar is sealed, it's important to store it in the right place. The best place to store a sealed jar is in a cool, dark place, such as a cupboard. Basements are also a good option, but the temperature should be kept in mind as colder temperatures can slow down the aging process. If you're looking for a faster aging process, consider storing the jar in a warmer environment or an area with temperature fluctuations, like an attic.

It's important to note that sunlight can affect the quality of the alcohol, so it's best to avoid storing the jar in direct sunlight or anywhere that may experience extreme temperature changes. Additionally, the storage location should be dry and free of moisture to prevent any potential mould or mildew issues.

When storing your sealed jar, it's also a good idea to label it with the date and contents. This will help you keep track of how long the jar has been stored and what it contains, especially if you plan to store multiple jars or different types of alcohol.

Before storing your sealed jar, make sure that it is properly sealed. You can test the seal by pressing on the lid with your finger; if there is any give, the jar may not be sealed properly. A properly sealed jar will also make a popping sound when you open it, indicating that a vacuum has been created inside.

By following these simple storage instructions, you can ensure that your alcohol-filled Mason jar remains in optimal condition and is safely stored for future use or enjoyment.
