Deer and Grapes: Do Deer Eat This Fruit?
As a backyard gardener or grape enthusiast, you may have wondered: do deer actually eat grapes? The answer may surprise you. Deer are known to have quite a diverse diet, and grapes, both the fruit and the vines, can be a tempting treat for these herbivores. But how much of a problem are deer when it comes to your prized grape harvest? Let’s explore the relationship between deer and this popular fruit.
Key Takeaways
- Deer are known to enjoy both the fruit and tender leaves/twigs of grape vines.
- Grape vines can be a significant food source for deer, especially in late summer and early fall when the grapes ripen.
- Deer can cause substantial damage to young, newly established grape vines by stripping the leaves and fruit.

The Deer’s Love for Grapes
Grape vines are a prime target for hungry deer. Numerous eyewitness accounts have documented deer enthusiastically grazing on grape leaves, shoots, and ripe fruit. Whitetail deer, in particular, display a strong preference for grapes and grape vines, devouring them with relish.
Grape Vines: A Favorite Snack for Deer
Deer find grape vines, especially young and tender ones, to be an irresistible delicacy. The damage they can inflict on vineyards is substantial, as they strip leaves, consume the fruit, and even trample the vines underfoot. This behavior can lead to significant losses for grape growers if proper deterrents are not implemented.
The problem is exacerbated by the fact that deer have a diverse diet, with a particular fondness for forbs (herbaceous flowering plants) over other food sources. Grapes and grape vines rank highly among their preferred foods, making them a constant threat to vineyards.
“Deer can go over a 6 feet fence, making it ineffective in deterring them.”
According to wildlife experts, the best way to identify deer’s preferred food sources in a specific region is by observing the signs of browsing in the area. Trampled plants, crushed fruits, and ragged, broken ends of branches are all telltale signs of deer activity.
Protecting vineyards from deer requires a multi-faceted approach, as a single deterrent method is often not enough to keep these determined foragers at bay. A combination of tactics, such as fencing, repellents, and other deterrents, is necessary to effectively safeguard grape vines from deer damage.
Protecting Your Vineyard from Deer
As a grape grower, protecting your vineyard from deer is a critical aspect of wildlife management. Deer can pose a significant threat to the health and productivity of your grape vines, consuming up to 50% of your Tempranillo grapes if left unchecked. Implementing an effective deer deterrent system is essential to safeguarding your valuable crop and ensuring a bountiful harvest.
Fencing: The Most Effective Deterrent
The most reliable method for protecting your vineyard from deer is the installation of tall, deer-resistant fencing. A 7-foot-tall fence spanning over a mile has proven to be highly effective in keeping deer out of the grape-growing area. This exclusionary barrier, combined with an electric fence, creates a comprehensive defense system that deters deer from accessing your valuable vines.
Other Deer-Deterrent Methods
In addition to fencing, grape growers can employ various other deer-deterrent methods to enhance their vineyard protection efforts. Motion-activated sprinklers, reflective devices, and repellents can all play a role in deterring deer from your property. For example, Nite Guard Solar Lights mimic the blinking eyes of a nocturnal predator, triggering the “fight or flight” response in deer and birds, while Plantskydd Animal Repellent has been shown to reduce damage by over 30% on 1,000 acres of treated vineyards.
Implementing a comprehensive deer management plan, which combines multiple deterrent strategies, is the key to successfully protecting your vineyard from deer.

Deer Diet: Do Deer Eat Grapes?
Deer are indeed known to eat grapes, both the fruit and the leaves of grape vines. Their fondness for grapes is well-documented, with numerous eyewitness accounts and reports of deer causing damage in vineyards. While grapes are not a primary component of a deer’s natural diet, they are considered a favored snack that deer will seek out and consume when available.
According to research, deer feed at dawn and dusk when they typically browse for food. A single slice of bread can be lethal for a deer, and they can starve to death with a gut full of hay due to its lack of nutrition. Deer enjoy a variety of fruits, including apples, grapes, blueberries, cranberries, raisins, bananas, and ripe pears.
Interestingly, deer are not interested in certain plants such as oregano, sage, rosemary, English and Spanish lavenders, and arugula. They leave small black poop balls as waste, and some deer buddies may leave behind fawns as caregivers take over. Deer feeding can be a rewarding hobby, although an expensive one, as their feeding needs are substantial.
“On average, an adult white-tailed deer consumes about 5-7 pounds of food per day, indicating their substantial feeding needs.”
White-tailed deer, in particular, prefer trees and shrubs such as white cedar, birches, aspens, and American yew, which are among their favorite food sources. During the winter months, when food sources become scarcer, it is common for people to provide supplemental feed deer to help sustain them.
However, it’s important to note that local laws may regulate feeding wildlife, with some states prohibiting deer feeding altogether. Gradually introducing new foods to deer is also crucial, as their systems take 2-4 weeks to adjust to a new diet, emphasizing the importance of a gradual dietary transition.
In conclusion, deer’s love for grapes is well-established, and their fondness for this fruit is evident in the numerous reports of their presence in vineyards. While grapes are not a primary component of their diet, they are considered a favored snack that deer will seek out and consume when available, highlighting the deer’s diverse diet preferences and wild deer feeding habits.
Grapes vs. Raisins: What’s the Difference?
While both grapes and raisins (dried grapes) are enjoyed by deer, there are some notable nutritional differences between the two. Understanding these variations can provide valuable insights into the dietary preferences and needs of these captivating creatures.
Nutritional Comparison
Raisins are significantly more calorie-dense than fresh grapes, containing almost four times the number of calories per serving. However, grapes are richer in certain vitamins and antioxidants, such as vitamin C and resveratrol. On the other hand, raisins have higher concentrations of minerals like copper and iron.
| Nutrient | Grapes | Raisins |
|---|---|---|
| Calories (per 100g) | 67 | 299 |
| Vitamin C (mg) | 3.7 | 0.3 |
| Resveratrol (mg) | 0.11 | 0.03 |
| Copper (mg) | 0.12 | 0.64 |
| Iron (mg) | 0.36 | 2.93 |
While deer can safely consume both grapes and raisins in moderation, the distinct nutritional profiles of these two fruits may influence their dietary preferences and selections. Deer’s natural inclination towards sweet and calorie-dense foods could contribute to their attraction to raisins, while the higher vitamin and antioxidant content of grapes may also appeal to their nutritional needs.
“Grapes have been part of the Indigenous North American diet for over 10,000 years, with various Native American nations utilizing them for food, medicine, and other purposes.”
By understanding the nutritional differences between grapes and raisins, wildlife enthusiasts and deer management professionals can gain valuable insights into the dietary preferences and needs of these fascinating animals.
