When and How to Harvest Juniper Berries

Juniper berries – which are actually cones, not berries at all – are incredibly versatile. They can be used to flavor drinks, savory dishes, and desserts.

They can also be used medicinally, or even to make a sourdough starter!

The trees that produce them thrive across the Northern Hemisphere, and if you live somewhere with extreme temperature variations between heat and cold, and long periods of dry weather, they probably grow happily in your neck of the woods.

If so, you’ve probably noticed them around. Maybe you’ve even wondered how to harvest the berries.

That’s what this guide will address. We’ll help you figure out when to harvest, how to do it, and how to preserve the fruits once you’ve gotten your hands on them.

But first, you need to ensure that you have a species that’s good to cook with or use in medicine.

Here’s what to expect:

Identify Your Species

Before you go nabbing the cones to eat or use medicinally, be sure of the species you are harvesting from.

Almost all species that are native to the US are totally fine to eat, but there are a few species from Europe and China that are poisonous, such as Juniperus sabina and J. oxycedrus.

If you eat a lot of juniper berries in one sitting, regardless of the species, it can make you sick. Don’t gorge yourself once you’ve harvested a bunch.

If you’re harvesting the cones to try to propagate a tree or for decorative purposes, the species isn’t important with regards to potential toxicity.

You should also keep in mind that there are some cedars and cypresses out there that look like junipers, but aren’t. The berries are the key to determining what species you’re dealing with.

Cypresses don’t produce small blue berries. Cedars have angular blue ones that may come to a point. Juniper berries, on the other hand, are round and blue.

Neither cypresses nor cedars smell distinctly pine-like, as the fruits from a juniper do.

How to Identify a Ripe Berry

You can’t eat or plant unripe berries, so it’s important that you know how to identify the ones that are ripe.

They can take up to three years to mature, depending on the species, and each tree or shrub will have berries of varying ripeness because they don’t all form and ripen uniformly.

The easiest way to tell if a berry is ripe is to tug it. It should give easily. You can even shake a juniper and the ripe ones will fall to the ground. If a berry resists, it’s probably not ready.

Most species have fruit that develops into some shade of blue, though some can be nearly white and others are practically indigo when ripe.

That’s why color isn’t a reliable indicator, unless you know which species you’re dealing with and what color the ripe fruits are.

You can also give the berries a little squeeze. They should feel plump with a little give. They won’t be as soft and juicy as, say, a blueberry, but they will have a definite give to them. Unripe ones feel firm and solid.

Many guides recommend harvesting in the fall and winter, and this is the most reliable time to find ripe fruits. But you can technically harvest year-round, depending on the species.

Be aware, however, that lots of birds and mammals like to eat them, so if you wait too long, they’re likely to get to them first. Fully ripe fruits may also fall off the tree before you can use them.

Don’t pick ripe berries up off the ground unless you laid a tarp there yourself, and shook the tree to make them fall.

The exception to all this is if you’re planning to make gin the traditional way, rather than flavoring a base like vodka that has already been distilled. In that case, you want to wait until the cone is fully formed and mature in terms of size, but still green. J. communis is the species typically used to produce gin.

How to Harvest

Before you start, ensure that you are foraging in safe areas away from roads, and only collect from plants that have not been sprayed with chemicals.

Technically, you can just lay a tarp down and shake that juniper tree until it gives up the goods. But this can knock unripe fruits off as well, depriving you and the fauna who eat them of future harvests. Better to hand pick the berries you want.

To do this, don some thick gloves and a long-sleeved shirt. Some junipers have soft scaly needles, but the same plant can also have spiky, sharp needles. You don’t want to get stabbed during your foraging adventures, so suit up.

That said, if you happen to be out wandering about and come across a juniper you can positively identify, even if you’re not appropriately adorned, you can carefully and safely pull the fruit off the plant. It just takes a little extra time and care.

Gently tug away any berry that looks ripe. It helps to have a basket or foraging pouch so you can keep your hands free.

Something water-resistant that attaches to your belt and has a wax lining, like this pouch made by Asenie, is ideal. It’s available on Amazon.

If you intend to use the wild yeast that covers the berries for home fermenting (that’s the powdery bloom you see), you might want to use a plastic or cotton bag so the yeast doesn’t get rubbed off.

Preservation and Storage Tips

You can dry the fruits to make them last longer, but be aware that this reduces the flavor.

To dry, wash them first if you wish, and place them in a food dehydrator or in a single layer on a cookie sheet in the oven at the lowest setting.

Leave the fruits to dry until they are hard and dry, much like a peppercorn with a slightly leathery skin.

Place in a resealable jar and store in a cool, dry spot out of the light.

Otherwise, you can just place the fresh fruits in a container. Only fill it about halfway to allow for some airflow.

Even better, use a container that doesn’t seal entirely but allows the air to flow. I like to use canning jars with a few holes poked in the lids.

This should also be placed in a cool, dry place without exposure to direct sunlight.

Dried fruits can last for years in a sealed container. Fresh fruits can last a year, if stored properly.
