How to Protect Wine During Summer

As summer temperatures increase, the likelihood of wine spoilage during transportation also escalates. Planning and appropriate packaging can significantly contribute to maintaining flavor, aroma, and overall customer satisfaction. Let us explore the most effective methods for protecting wine during summer shipping and storage.

Why Summer Heat Is a Problem for Wine

Wine is delicate. It doesn’t like temperature swings or direct heat, and summer brings plenty of both. Prolonged exposure to temperatures above 75°F (24°C) can “cook” your wine, ruining its taste and aging potential. When wine gets too warm, it expands. That expansion can push the cork out slightly or create pressure that compromises the seal letting oxygen in, which leads to oxidation and spoilage.

In short, heat is wine’s worst enemy, especially in transit.

Choose the Right Packaging Materials

Your first line of defense? Smart packaging.

• Insulated Shippers: Use wine shipping boxes designed with insulation. Foam or molded pulp inserts add extra protection by minimizing temperature transfer and keeping bottles stable.

• Air Cushion Shippers: These add thermal and shock resistance while keeping bottles securely in place. They're ideal for short- to mid-range shipping.

• Double-Walled Outer Boxes: Durable, corrugated outer boxes add a thermal buffer and help shield from external heat.

All these work together to keep the wine bottle’s environment stable—just what you need during summer.

Time It Right

Timing is everything.

• Avoid Weekend Shipping: Ship early in the week. Monday or Tuesday so your wine doesn’t get stuck in a hot warehouse over the weekend.

• Choose Express Shipping: It may cost a bit more, but faster delivery means less exposure to temperature changes.

• Check the Forecast: If a heatwave is expected in your recipient’s area, delay your shipment for a few days. It’s worth the wait.

Cold Packs and Gel Packs

Another good option is adding cold packs to your shipment. These gel-based inserts help regulate temperature inside the box for 24 to 72 hours. They work well when combined with insulated wine shipping kits.

Make sure the cold packs are properly positioned, ideally around but not touching the bottle, to avoid any direct freezing or damage to the label.

Use Temperature-Controlled Shipping Services

Some shipping carriers offer temperature-controlled trucks or refrigerated shipping for alcohol and perishables. This is especially important for longer routes or bulk orders. You can also look into summer shipping programs offered by fulfillment companies that specialize in wine.

Store Smart Before Shipping

If you’re storing wine before shipment, make sure it’s in a cool, dark space. Ideal conditions for wine storage are around 55°F (13°C), with stable humidity and minimal light exposure. Keeping wine cool until the moment it’s boxed up adds an extra layer of protection.

Label Clearly

When shipping wine during hot months, it ia a good idea to mark your boxes with "Perishable" or "Keep Cool." This alerts handlers and shipping carriers to treat the package with a bit more care.
