How long can you drink iced tea after opening?

Quick Answer

Iced tea that has been freshly brewed and stored properly in the refrigerator can stay good for up to 7-10 days after opening. After this time, it’s best to discard the iced tea and brew a fresh batch. The shelf life depends on a few key factors like tea type, storage conditions, and ingredients used. Diluted, bottled iced tea typically lasts 5-7 days refrigerated.

How Long Does Brewed Iced Tea Last Refrigerated?

Freshly brewed iced tea that is promptly refrigerated will stay good for 7-10 days after being prepared. Since iced tea lacks preservatives and contains perishable ingredients like real tea leaves, fruits, herbs, etc., it has a relatively short shelf life compared to commercial bottled iced tea.

Follow these storage tips to maximize the shelf life of refrigerated iced tea:

– Store in an airtight container like a pitcher with a lid or a covered mason jar. This prevents moisture loss and contamination.

– Refrigerate right after brewing, don’t leave at room temperature. Promptly chilling below 40°F (4°C) inhibits microbial growth.

– Use clean utensils and containers. Sanitize any equipment that contacts the tea.

– Don’t let tea leaves remain in contact with the brewed tea for more than a few hours. The leaves can start to impart off-flavors.

– Check the tea for any odd smells, flavors, or sliminess that indicate spoilage.

The exact shelf life depends on these factors:

Type of Tea

More delicate green and white teas will deteriorate faster, while heartier black teas have a slightly longer shelf life, around 10 days.


Fruit, herbs, and juices shorten refrigerated shelf life. Plain tea lasts longest.


Higher acidity helps prevent bacterial growth. Avoid bitterness, as overly strong tea degrades faster.

Storage Temperatures

Temps closer to 32°F are ideal. Open and closed containers have slightly different temperature needs.


Sanitary tools, containers, and hands prevent contamination and spoilage.

How to Tell if Brewed Iced Tea Has Gone Bad

Watch for these signs that refrigerated iced tea has spoiled and should be discarded:

Appearance: Cloudiness, haziness, particles

Aroma: Smells sour, fermented, or odd

Flavor: Strange taste, increased bitterness or acidity

Texture: Extra thick, slimy, gritty, moldy film

Time: More than 10 days since brewing

As iced tea nears its use-by date, oxidation can also degrade quality without making it unsafe. Stale iced tea may taste flat, lacking aroma and brightness. Discard iced tea once it doesn’t taste optimally fresh.

Factors that Shorten Iced Tea Shelf Life

Several variables lead to iced tea expiring quicker:

Higher Temperature – Warm fridges under 40°F hasten spoilage. Store chilled below fridge door, not on door shelves.

Sunlight Exposure – UV light damages antioxidants and flavors over time. Use an opaque container.

Oxygen – Exposure through headspace oxidizes and degrades quality. Minimize air contact.

Tea Strength – Overbrewed, bitter tea decreases stability and shelf life.

Sugars and Sweeteners – Added sugars are vulnerable to fermentation. Limit amounts.

Fruit Juice – The sugars and acidity in juices make iced tea spoil faster than plain.

Herbs and Add-Ins – Natural plant matter reduces shelf life compared to tea alone.

Following proper storage methods minimizes these risks of faster deterioration. Regularly monitoring the appearance, smell, taste, and texture will also indicate when refrigerated iced tea is still safe to drink.

Does Iced Tea Go Bad or Expire?

Yes, brewed iced tea has a limited shelf life and will eventually expire. Chemical changes during storage lead to lower quality, degraded flavors, and potential bacterial growth.

Iced tea contains water, natural plant compounds, and sometimes fruit juices or sweeteners. None of these ingredients preserve it for an extended duration without refrigeration.

Over time, oxidation causes iced tea to lose its fresh aroma and taste vibrant. If stored for too long at warm temperatures, pathogens can multiply, making iced tea unsafe. Refrigeration simply delays the inevitable reduction in quality.

So while iced tea doesn’t have a firm expiration date like ultra-pasteurized milk, its freshness does gradually decline. Follow your senses to determine if chilled iced tea still smells, looks, and tastes pleasant. Discard at the first signs of spoilage.

How Long Does Brewed Iced Tea Last at Room Temperature?

Brewed iced tea left out at room temperature should not be kept for more than a few hours before refrigeration. The danger zone between 40°F and 140°F allows bacteria to quickly multiply to unsafe levels.

Here are some general guidelines for maximum times brewed tea can safely be left unrefrigerated:

– 1-2 hours below 90°F (32°C)

– 30 minutes if above 90°F (32°C)

– Discard immediately if over 140°F (60°C)

Drinking contaminated iced tea risks foodborne illness. Keep newly brewed tea chilled in the refrigerator, not on the kitchen counter. Put in an ice bath to quickly cool if needed.

If reheating refrigerated tea for serving, don’t keep warm more than 30 minutes before discarding. Reheating previously chilled tea can also degrade flavor. For best quality and food safety, freshly brew a new pitcher to replenish iced tea at room temperature.

Does Iced Tea Go Bad If Not Refrigerated After Opening?

Yes, iced tea will spoil if left unrefrigerated after opening. The contents are no longer sterile once exposed to air, light, and warmer temperatures.

Without refrigeration, brewed iced tea allows:

– Microbial growth – bacteria, mold, yeast

– Oxidation reactions – fading color, loss of flavor

– Enzymatic breakdown – bitterness, cloudiness, sediment

Once opened, keep iced tea chilled below 40°F and drink within 7-10 days for optimal quality and safety. Don’t store at room temperature after brewing.

Follow your nose and taste buds when evaluating older tea. Discard if you detect off-odors, sourness, or strange flavors. Never consume iced tea that smells or looks abnormal. Refrigeration is vital for preventing this foodborne illness risk.

How Long Does Sweet Tea Last After Being Made?

The shelf life of sweet tea depends on the brewing method, sweetener used, and storage conditions. In general, refrigerated sweet tea retains good quality for 5-7 days after being made.

Because the added sugars or sweeteners are vulnerable to fermentation, sweet tea has a shorter shelf life than unsweetened iced tea. Here are some shelf life guidelines for different types of sweet tea:

Simple syrup sweetened – 7-10 days

Sugar sweetened – 5-7 days

Stevia/Splenda sweetened – 7-10 days

Honey sweetened – 5-7 days

Avoid leaving sweetened tea out more than 2 hours before refrigeration. The sugars allow rapid microbial growth at room temperature.

Prevent fermentation and elongation by refrigerating sweet tea promptly in an airtight container. As with unsweetened tea, watch for any odd smells, textures, appearance, or flavors as the expiration date approaches.

How Long Does Homemade Iced Tea Last in the Fridge?

The shelf life of homemade iced tea stored in the fridge depends on the ingredients and recipe. Assuming proper refrigeration, here are some general guidelines:

Black iced tea – 8-10 days

Green/white iced tea – 5-7 days

Herbal iced tea – 7-10 days

Fruit-infused iced tea – 3-5 days

Sweet iced tea – 5-7 days

To maximize freshness in the fridge, brew tea at room temperature according to package directions. Steep for just the recommended time to avoid overbrewing. Chill brewed tea immediately by placing the pitcher or jar in an ice bath, then refrigerating.

Avoid introducing contaminants by using sanitized equipment and washing hands properly. Store refrigerated iced tea in an airtight container, not the brewing pitcher.

Does Bottled Iced Tea Go Bad?

Yes, bottled iced tea eventually goes bad and should not be consumed past its expiration date. Commercially packaged iced tea lasts longer than homemade due to pasteurization and added preservatives. But it still has a limited shelf life.

The fridge shelf life of bottled iced tea depends on these factors:

Processing method – Pasteurized lasts longer than cold-brewed

Preservatives – Ingredients like citric and ascorbic acid help prolong shelf life

Bottle material – Glass aids shelf life compared to plastic

Tea type – Black tea may last slightly longer than green

Sweeteners – Sugar, HFCS shorten shelf life compared to unsweetened

Once opened, bottled iced tea typically stays fresh for 5-7 days refrigerated. Check the best by date printed on the bottle and be alert for any changes in appearance, aroma, taste, or texture before drinking. Discard if you notice anything off.

How Long Does Bottled Iced Tea Last When Opened?

Once opened, bottled iced tea typically lasts 5-7 days in the refrigerator before going bad. This is shorter than the unopened shelf life of 3-9 months. Exposure to air and light immediately start degrading the quality once the original seal is broken.

Follow these guidelines for maximizing the opened shelf life:

– Refrigerate after opening. Don’t leave unsealed bottles out.

– Reseal the bottle tightly or transfer to a sealed container. Prevent air contact with the liquid.

– Drink from clean glasses to avoid back-contamination. Don’t drink straight from the bottle.

– Watch for any changes in appearance, smell, or bubbling. Discard if anything seems off.

– Observe the manufacturer’s “best by” date. Consume within 5-7 days of opening.

The less airspace inside the bottle, the better. Transferring opened tea to a smaller container can help minimize oxidation while refrigerated.

How to Store Iced Tea Properly?

Here are some tips for properly storing brewed or bottled iced tea to maximize shelf life:

Air-tight container – Prevent oxygen exposure in sealed mason jars, pitchers, or bottles.

Opaque – Block light in colored plastic or ceramic containers to slow reactions.

Refrigerate – Chill below 40°F, colder is better. Monitor fridge temperature.

Smaller volume – Less airspace means less oxidation. Use smaller containers.

Sanitize equipment – Clean utensils, containers, hands thoroughly before use.

Don’t sweeten until serving – Adding sugars speeds up spoilage. Sweeten each glass.

Clean serving tools – Don’t introduce bacteria through unclean cups, stirring instruments.

Date container – Mark when tea was brewed using labels or tape.

Proper refrigeration and sealed storage are the keys to maximizing how long iced tea stays fresh, delays deterioration, and prevents potential microbial hazards.

How Long Does Iced Tea Last in the Freezer?

While refrigerating iced tea is better for preserving fresh taste, properly frozen iced tea can last 6-8 months in the freezer before deteriorating in quality.

To freeze brewed tea:

– Chill brewed tea in the fridge before freezing for faster temperature reduction.

– Pour tea into freezer-safe plastic or glass containers, leaving 1⁄2 inch headspace.

– Seal tightly with freezer-safe lids or extra plastic wrap.

– Freeze for up to 6 months at 0°F or below.

– Thaw in the refrigerator before consuming for food safety.

Freezing stops the growth of bacteria and slows the chemical reactions that lower iced tea quality over time. However, condensation after thawing can lead to some dilution of flavors.

For best taste, drink thawed frozen tea within 24 hours. Discard if you notice any odor or color changes during storage.

Can You Refreeze Thawed Iced Tea?

Previously frozen iced tea should not be refrozen after thawing for both quality and safety reasons. The condensation formed as tea thaws will create undesirable ice crystals during a second freeze.

Dangerous pathogens like Listeria can also multiply faster in iced tea thawed at fridge temperatures then refrozen. For food safety, only refreeze iced tea if these conditions are met:

– Never thawed more than 2 days in the fridge

– No visible signs of spoilage

– Kept chilled below 40°F prior to refreezing

– Only thawed and refrozen once

Even if safely refrozen, the quality of the iced tea will degrade with each additional thaw cycle. The ice crystals disrupt the beverage’s texture and flavor.

For the best quality tea, avoid refreezing thawed iced tea. Either drink thawed tea within a day or two or discard and make a fresh batch.

How to Tell When Thawed Iced Tea Has Gone Bad?

Check for the following signs that thawed, previously frozen iced tea has spoiled and should be discarded:

– Unpleasant or strange odors

– Mold, sliminess, cloudiness

– Fizzing, bubbling, fermented taste

– Sour, bitter, or otherwise “off” flavors

– Changes in appearance or texture

– More than 5-7 days refrigerated after thawing

Trust your nose – if thawed tea smells odd or funky, do not consume it or taste it. Changes in aroma indicate microbial growth. Discard immediately.

Avoid leaving thawed tea for longer than 5-7 days refrigerated. To limit the time tea spends thawed, only remove the needed portion from the freezer, not the entire batch. Promptly refreeze anything not consumed.

When in doubt, throw it out. Iced tea is inexpensive and easy to brew fresh. Don’t risk getting sick from a questionable batch.


The shelf life of iced tea depends on ingredients, storage methods, and preparation. In general, homemade brewed tea keeps 1-2 weeks refrigerated while commercial bottled tea can last 2-3 months sealed. Once opened, store iced tea in the fridge and drink within a week for safety and optimal quality. Proper chilling inhibits microbial growth while sealed containers prevent oxygen exposure. Monitor the aroma, appearance, and flavor of iced tea, discarding if anything seems off. With appropriate refrigeration and handling, both brewed and bottled iced tea can be safely enjoyed within a reasonable timeframe before spoiling occurs.
