While grapes from the Mediterranean may be considered more desirable, the US has a substantial amount of domestic vineyards, particularly in California. If you have grapes to ship within the United States, learning more about the process before you start can save you trouble later down the road.

Key Takeaways

  • Due to their delicate skins and short shelf life, grapes must be transported in refrigerated trucks at approximately 32°F with humidity control and minimal handling.
  • Consumer grapes are often shipped in ventilated plastic bags or clamshells, packed in 10kg cartons, and palletized.
  • Only ship healthy, fully ripened grapes free of bruises, odors, and mold. Even visually unappealing grapes may be rejected by buyers despite being edible.
  • Sulfur dioxide treatment is commonly used to prevent mold during transit. It is safe for consumption when properly applied.

In this article, I’ll cover all the juicy details of transporting grapes via freight.

Transporting Grapes in the United States

In order to transport grapes, they need to be ripe and healthy. Grapes won’t continue to ripen after they are harvested, so they must be picked at just the right time. 

Before transport, grapes need to:

  • Show no abnormal odors or flavors
  • Be free of bruises or pressure marks
  • Not have any atypical moisture
  • Be free of burst or shriveled specimens 

Customers may turn down a shipment of grapes if it’s simply not visually appealing, even if there is nothing technically wrong with it. Ensure that all grapes are the correct color, size, and ripeness before attempting to transport them. Otherwise, they may get rejected for not meeting quality standards.

Securely Packaging Table Grapes

Grapes not intended for processing into juice or wine must be packaged in a particular way to minimize shipping damage. Grapes often have a long transit when shipped within the US, which means they can’t exactly be thrown in a buggy and pulled by horses anymore. 

Most of the time, table grapes are shipped in plastic bags with little holes for ventilation, and a ziplock style slider seal. Sometimes, standard clamshell packaging is used to offer more protection to the delicate fruits. Those smaller containers are packaged in a sturdy 10kg (22lb) crate or carton with wool, polyethylene, or cardboard to protect it. Finally, these cartons are palletized for easy shipping.

To palletize grape shipments, here are a few best practices to employ:

  • Ensure that the crates are sturdy, so the bottom layer can support the weight of the other crates stacked on top of it.
  • Stagger the crates if possible to maximize airflow.
  • Distribute the weight of each box evenly.
  • Place large sheets of cardboard between layers to increase structural integrity.
  • Ensure that the pallet does not exceed 5 feet (or 60 inches) in height.
  • Wrap the entire pallet in shrink wrap at least three times, and make sure the wrap is firmly attached to the pallet.
  • For added security, consider strapping the entire stack of crates to the pallet with nylon straps. 

Palletizing your shipment has many benefits. Not only does it protect the freight, it also makes it much easier to handle for the carrier transporting it. In some cases, your freight may incur extra fees if it is not palletized, or if it was palletized incorrectly.

Packaging Grapes for Wholesale

Grapes intended for wine or juice must be packaged differently from consumer table grapes. Because juice and wine grapes are not sold to supermarkets for consumers, they do not need to be individually packaged for the grocery store shelves. Instead, wine and juice grapes are best packaged in bulk containers to be sent to juice makers and winemakers. 

To transport grapes for wholesale, growers typically utilize wooden or plastic pallet bins. The bins are the same width and length as a normal pallet, so that makes it easy to transport with a forklift. There is no standard height for a pallet bin, and it may be able to accommodate as few as 12 to as many as 50 bushels depending on the type. Once packed, these pallet bins can be stacked on top of each other just like normal pallets. 

Although pallet bins are a popular choice because of the low cost, there are many other options for shipping bulk grapes to a juice maker or winemaker, like:

  • Wire-bound or wooden crates
  • Baskets
  • Hampers
  • Corrugated fiberboard

Whether intended for eating or processing into wine and grape juice, these delicate fruits have specific temperature requirements that must be followed to prevent spoilage.

Cold Chain Logistics in Grape Transport

Transporting grapes and other fresh fruit with a short shelf life means employing cold chain logistics. This process involves moving and storing fruits, vegetables, and other commodities at cool/cold temperatures to maintain freshness. This is especially important for grapes, as they are delicate and sensitive to changes in temperature.

Since there are often many stops in the logistics process, that means more than just the truck that moves the grapes needs to be kept cold. Warehouses, trucks, and destination ports must all be the correct temperature to keep the grapes fresh. 

A temperature of 0 degrees Celsius, or 32 degrees Fahrenheit, is recommended for storing and transporting grapes. If at any point in the process, the shipment is stored at the wrong temperature, it is likely to be rejected at the destination. This can result in profit loss for the carrier, the shipper, and any involved third parties. To ensure that this does not happen, it is important to only work with trusted, highly qualified carriers.

Time Sensitive Delivery

As with any perishable food, grapes must be transported quickly to ensure freshness. If a shipment takes too long, it may spoil before it reaches its destination—even if it was kept at the correct temperature the whole time! 

Even though grapes won’t continue to ripen after harvest, the fruit’s metabolic processes will continue. The grapes can absorb oxygen and excrete carbon dioxide after harvest. This causes starch in the grapes to turn into sugar and can make them go bad. It is important to be aware of this natural process during shipping.

For this reason, grape shippers benefit from having warehousing options in multiple areas if you intend to ship your grapes around the nation. This way, the transit time between the warehouse and the destination can be significantly reduced, and the grapes can arrive as fresh as possible. 

Humidity and Moisture Control

It is very important to be aware of fungus and bacteria when transporting grapes. In fact, fungus is one of the most common and obvious causes of grape deterioration when in storage and being transported. A fungus called Botrytis cinerea is a common cause of grape deterioration. It causes grapes to rot and covers them with a gray coating. 

Bacteria and fungi require a moist environment to grow, so precautions should be made to ensure that the packaging is not too moist, but not so dry that the grapes shrivel up. Crates and cartons should be well ventilated to encourage airflow, so moisture does not accumulate or stagnate. Grapes should be kept in a semi-humid environment for best results, but there is a fine line between humidity and moisture.

To make sure the shipment is kept at the proper humidity levels, you should inform your carrier of the specific requirements that apply to your shipment. If you fail to do so, they won’t be held liable for grapes that spoil in transit. 

Alternatively, you could enlist the help of a freight broker, who would communicate with the carrier on your behalf. They would also be responsible for researching the requirements of your shipment and keeping the carrier informed of your expectations. Since they keep track of all the rules that apply to freight shipping grapes, they’re a huge asset to a busy shipper.

Fumigating Grapes to Prevent Fungal and Bacterial Infection

Another tactic used to try to control bacteria, fungi, and diseases is fumigation. Grapes that are selected for shipment are treated with a gas called Sulfur Dioxide to kill the Botrytis cinerea that may have already infected the plant and protect against future contamination of the disease. This form of fumigation is not detrimental to the quality of the grapes or the health of the consumer.

There are two main ways that grapes get fumigated with sulfur dioxide: Total Utilization and sulfur dioxide releasing pads.

  • Total Utilization: The process leaves no trace of the fumigant, meaning that it is not only better for the grapes, but it is also better for the environment since the sulfur dioxide is not released into the air. Because it does not leave a residue behind, the grapes need to be treated on a weekly basis in order to remain safe while in storage.
  • Release Pads: This method involves placing a pad that releases a strategic amount of sulfur dioxide over a period of time underneath the grapes during transport. This pad also has the added benefit of absorbing excess moisture in the crate, discouraging mold growth.

Fumigating grapes is tricky due to their delicate nature. The levels of sulfur dioxide used during fumigation have to be carefully calculated, since overexposure could ruin the quality of the fruit.

Signs that the grapes were overexposed to sulfur dioxide are:

  • Brown or bleached spots on the skin
  • Brown or gray discoloration where the grape connects to the stem
  • Sunken or deflated looking areas

As an added benefit to sulfur dioxide fumigation, the process actually prevents the stems of the grapes from turning brown, which makes the bunch look much more visually pleasing and marketable.

Cost of Transporting Grapes

Freight costs are a major consideration for any producer or manufacturer. Shipping your products around the U.S. and the world brings it to consumers, so they can more readily make a purchase, and drive immense revenue. If you only sold locally, you would severely limit your potential revenue, so it is incredibly important for any growing business to expand into the realm of interstate shipping. 

Grapes must be shipped in a full truckload, or FTL, shipment. This is mostly because they must be kept at a specific temperature during the shipping process, and flavors from other produce may contaminate the grapes. Additionally, the container should not be opened until it reaches the destination to avoid temperature increases. This makes shipping grapes a little more expensive than shipping something like plastic trinkets, which can be shipped LTL. 

Some of the factors that are used to determine the cost of the shipment are:

  • The distance to its destination
  • Whether the destination is in a major city, like New York or Houston
  • When the shipment needs to arrive
  • Whether there are any abnormal weather conditions that could make driving more difficult, like rain, snow, or hail
  • The value of the shipment
  • The size of the shipment, and the number of trucks that would be needed 

If you want to know the cost of your specific shipment, the best way to do that is to get a quote from a shipping company or a third-party logistics company.
