Do Simply smoothies need to be refrigerated?

Simply Smoothies are a popular brand of pre-made fruit and vegetable smoothies that can be found in the refrigerated section of most grocery stores. But do they really need to be kept cold, or can they be stored at room temperature like other shelf-stable drinks? Here is a look at whether Simply Smoothies need to be refrigerated for optimal quality and safety.

The Importance of Proper Refrigeration

Simply Smoothies are made by blending together fruit juices, fruit purees, yogurt, and other ingredients. They do not contain any preservatives or heat treatment that would enable them to be shelf-stable. Refrigeration is important for a few key reasons:

  • Slows microbial growth – Keeping Simply Smoothies refrigerated at 40°F or below slows the growth of bacteria, mold, and other microbes that could spoil the smoothie or cause foodborne illness.
  • Maintains texture – Ingredients like yogurt and pureed fruit will break down over time at room temperature, changing the smoothie’s intended thick, creamy texture.
  • Preserves nutrients – Vitamins like C and B, antioxidants, and other nutrients degrade more quickly when not refrigerated.
  • Retains flavor – Warm temperatures hasten chemical reactions that cause loss of fresh, fruity flavors.

Proper refrigeration helps Simply Smoothies maintain their intended quality and safety throughout the printed shelf life.

Shelf Life When Refrigerated

When stored continuously at 40°F or below, the shelf life printed on Simply Smoothie bottles ranges from 14-21 days from the manufacturing date. The shelf life varies based on the specific ingredients in each smoothie variety. For example:

  • Simply Strawberry smoothie – 14 day shelf life when refrigerated.
  • Simply Mixed Berry – 21 day shelf life when refrigerated
  • Simply Peach smoothie – 14 day shelf life when refrigerated.

The shelf life refers to how long the smoothie maintains peak quality when refrigerated. The Smoothies do not instantly spoil or become unsafe to drink right after the printed date, but quality degradation will be noticeable. Always inspect refrigerated Simply Smoothies for signs of spoilage before drinking.

Signs of Spoilage

Here are some signs that a refrigerated Simply Smoothie has spoiled and should be discarded:

  • Change in texture – Smoothie becomes thinner and more watery or has lumps of thickened, gelled fruit puree.
  • Mold – Fuzzy mold growing on the surface or below the bottle lid.
  • Off odors – Smells yeasty, rotten, or unpleasant instead of fresh.
  • Fizzing – Bubbles or hissing sound when bottle is opened due to CO2 from microbial growth.
  • Discoloration – Unnatural colors like blue, green, or black from mold or bacterial pigments.

If a refrigerated smoothie exhibits any of these warning signs, it is best to err on the side of caution and discard it.

Can Simply Smoothies Be Left at Room Temperature?

Simply Smoothies are designed to be refrigerated for the entire shelf life. However, brief temperature fluctuations outside of refrigeration, such as during transport from the grocery store or while left on the counter for immediate consumption, are unlikely to make the smoothies unsafe. Here are some general guidelines for temperature abuse:

  • Less than 2 hours at temperatures <70°F - Smoothie quality and safety unlikely to be impacted.
  • 2-4 hours between 70-90°F – Quality begins degrading but smoothie still safe if cooled down to fridge temps.
  • Over 4 hours above 90°F – At increased risk for higher microbial growth and rapid quality loss. Best to discard.

When in doubt, it’s better to be safe and toss out Simply Smoothies that have sat at room temperature for over 4 hours. The vegetable-based smoothies are more prone to quality loss from temperature abuse than fruit-based ones. Leaving an opened bottle unrefrigerated is also riskier than an unopened one due to increased oxygen exposure.

Can Simply Smoothies Be Frozen?

Freezing is an excellent way to extend the shelf life of Simply Smoothies beyond the printed date. Here are some freezing tips:

  • Freeze unopened bottles up to 2-3 months past the “best by” date.
  • Let thawed smoothies sit at room temp for 15 min before consuming for optimal texture.
  • Do not refreeze a smoothie after thawing.
  • Freeze opened bottles in an airtight container up to 1 month.
  • Stir after thawing – separation is normal.

The high water content and lack of cream means Simply Smoothies freeze solid and thaw well. Fruity flavors remain intact but veggies may get slightly cooked flavors. Always inspect for signs of spoilage after thawing.

Tips for Maintaining Quality

Here are some tips for keeping Simply Smoothies fresh and delicious:

  • Minimize temperature fluctuations – Avoid leaving smoothies out of refrigeration as much as possible.
  • Check “best by” dates – Purchase bottles with furthest expiration dates.
  • Use oldest first – Rotate inventory to use up older bottles sooner.
  • Clean lids and bottles – Wash before opening to avoid contamination.
  • Store tightly sealed – Limit oxygen exposure for better preservation.
  • Consume promptly – Try to drink opened bottles within 3-4 days.

Adhering to proper refrigerated storage and avoiding prolonged warm temperatures are the most important factors for maintaining Simply Smoothie safety and quality.

Nutrition & Ingredient Facts

One 11 fluid ounce bottle of Simply Smoothies provides the following general nutrition:

Nutrient Amount
Calories 150-350
Total Fat 0-5g
Sodium 45-120mg
Total Carbohydrate 30-50g
Dietary Fiber 1-4g
Sugars 25-45g
Protein 2-6g

Simply Smoothies are made from fruit juices and purees such as strawberry, peach, mango, blueberry, and banana. Common additional ingredients include:

  • Nonfat yogurt
  • Whey protein
  • Natural flavors
  • Pectin
  • Vitamin C
  • Vegetable juices like carrot, spinach, or beet

Smoothies are lactose-free and some varieties are made with non-dairy yogurt. Always check labels for ingredients of concern due to allergies or dietary restrictions.


Simply Smoothies undergo a pasteurization process to destroy pathogens like Salmonella, E. Coli, and Listeria. Pasteurization involves heating the smoothie to at least 145°F for 30 minutes or 161°F for 15 seconds, then rapidly cooling it. This high-heat short-time (HHST) process preserves more nutrients than prolonged heating methods.

Pasteurization makes the smoothies safe for people with weakened immune systems like pregnant women, the elderly, and young children (though not intended for infants). However, the lack of preservatives means proper refrigeration is still critical.

Common Varieties

Simply Smoothies come in a wide range of flavor combinations. Here are some popular varieties:

Flavor Name Description
Strawberry Banana Blend of strawberry juice and banana puree
Tropical Fruit Pineapple, mango, passionfruit, and banana
Peach Pear Apricot Peach and pear juice with apricot puree
Super Berry Blueberry, pomegranate, and acai juices
Green Machine Apple, kale, spinach, cucumber, and avocado
Carrot Apple Ginger Carrot juice with apples and ginger

Limited edition and seasonal flavors are also rolled out throughout the year.

Potential Health Benefits

When consumed as part of a healthy diet, Simply Smoothies may provide:

  • Immune support – Vitamin C and antioxidants from fruit juices can boost immunity.
  • Hydration – High water content helps the body stay hydrated.
  • Fiber – Most varieties provide 2-4g of filling fiber per bottle.
  • Energy boost – Natural sugars and calories provide fast fuel for the body.
  • Nutrient intake – Good source of potassium, vitamins A and C, folate, and more.
  • Disease prevention – Phytonutrients in fruits and veggies may lower disease risk.

However, the high natural sugar content means smoothies should be consumed in moderation as part of an overall balanced approach to nutrition and health.

Downsides and Considerations

Potential downsides of Simply Smoothies to keep in mind include:

  • High in natural sugars – Added sugars are not used, but total sugars range from 25-45g per bottle.
  • Lower in fiber – Less viscous and fibrous compared to homemade smoothies.
  • Not a meal replacement – Still requires balanced eating for complete nutrition.
  • High perishability – Requires diligent refrigeration and has short shelf life.
  • Risk of contamination – Potential for bacteria growth if repeatedly opened or poorly handled.
  • Not for infants – Choking risk from thick texture.

Those monitoring sugar intake or with diabetes should exercise particular caution. As with any food product, proper safety and storage practices are essential as well.

Cost and Availability

Simply Smoothies typically retail for $2-3 per 11oz bottle at most major grocery chains such as Kroger, Safeway, Publix, Whole Foods, and Trader Joe’s. They are stocked in the refrigerated produce or juice section. Selection varies by retailer and region.

Simply Smoothies can also be purchased online through the company’s website, Amazon, and other major retailers. Delivery requires expedited cold shipping which increases the cost per bottle.


Those looking for shelf-stable, refrigeration-free smoothie options may want to consider:

  • Bottled protein shakes
  • Aseptic boxed smoothies
  • Powdered smoothie mixes
  • Canned or jarred smoothies
  • Dried fruit and veggie smoothie powders

However, these utilize preservation methods like pasteurization, concentrate forms, and preservatives which alter the flavor and nutrition profile. Homemade smoothies are the freshest alternative but require more time and ingredient access.


In summary, Simply Smoothies are a convenient on-the-go beverage made from blended fruits and vegetables. Due to the lack of preservatives or high pressure processing, refrigeration at 40°F or below is required to maintain quality and prevent potential microbial growth. The smoothies can withstand brief temperature fluctuations but should not be left unrefrigerated for more than 4 hours, especially if opened. Adhering to safe handling and the printed “best by” date is recommended. When stored properly, Simply Smoothies provide an easy way to increase fruit and vegetable intake and get essential vitamins and minerals.
