How Are Almonds Made? The Fascinating Journey Explained
How Are Almonds Made?
Almonds are made through a multi-step process.
First, they are harvested when the outer husk dries and splits open.
Smaller producers pick them by hand, while industrial processors use tree-shaking machines.
Once harvested, the almonds are filtered to remove loose debris and stones.
The outer hulls are then removed, and the almonds are sorted using vibrating sieves.
Imperfections and contaminants are removed through camera inspection and bursts of air.
Technicians hand-pick any remaining imperfect almonds.
Size separation is done using a sieve-like conveyor belt.
Only perfect almonds proceed to the final stage, while those with superficial chips are sold for other uses.
The almonds are packed into large boxes and transported to other facilities for further processing into various products.

Did You Know?
1. Almonds are not actually nuts; they are seeds. They come from the fruit of an almond tree, which is botanically classified as a drupe.
2. Almond trees are considered to be environmentally friendly because they are pollinated by bees, making them a crucial component of sustaining bee populations.
3. California, specifically the Central Valley, produces 80% of the world’s almonds! It is the largest almond-producing region globally.
4. To ensure almonds have a longer shelf life, they go through a pasteurization process. Two common methods are steam pasteurization and dry roasting.
5. Do you know the difference between “sweet” and “bitter” almonds? Sweet almonds are the ones we consume, while bitter almonds are toxic due to their natural cyanide content. However, bitter almond oil, which is derived from the seed, is used in small quantities as a flavoring agent in the culinary industry.
Harvesting And Processing Almonds
The journey of how almonds are made begins in late August to early September when the outer husk of the almond fruit dries and splits open, revealing the precious nut inside. The timing of the harvest is crucial to ensure that the almonds have reached their optimal maturity and flavor. Small-scale almond producers often rely on manual labor, with workers carefully hand-picking the almonds from the trees. On the other hand, industrial processors employ tree-shaking machines to vigorously shake the trees, allowing the ripe almonds to fall to the ground.
Once the almonds are harvested, the raw nuts undergo a series of processing steps to prepare them for consumption. The first step involves passing the almonds through a machine that filters out loose debris such as twigs and leaves. This ensures that only the pure almonds move forward in the production process, eliminating any unwanted foreign elements.
Removing Debris And Stones
After the initial filtration process, the almonds undergo an additional step to eliminate any remaining impurities. The nuts are fed into a destoner machine, which employs air pressure to separate stones or rocks from the almonds. This highly effective technique guarantees that only the wholesome nuts proceed on their journey.

- Destoner machine uses air pressure to separate impurities from almonds.
Removing The Outer Hulls
One of the distinguishing features of almonds is their outer hull, which needs to be removed to access the edible part of the nut. To accomplish this, the almonds are subjected to a process called hulling. This involves pushing the almonds between a heavy rubber roller and a belt, which gently crushes and separates the outer hulls from the almond kernels. The hulls are discarded, while the freed almonds move on to the next stage of the production process.
Sorting And Inspecting Almonds
In order to ensure the highest quality and consistency, almonds undergo a meticulous sorting and inspection process. Vibrating sieves with varying hole sizes are used to sort the almonds based on their size. Any empty or broken hulls are quickly vacuumed up, leaving behind only the perfect almonds that meet the desired size criteria.
To further enhance the quality control process, advanced camera systems are employed to inspect the almonds for imperfections and contaminants. If any are identified, bursts of air are released to remove them from the stream of almonds. Additionally, machines grade the almonds based on shell conditions and perform inspections to identify any broken shells.
- Vibrating sieves are used to sort the almonds based on size.
- Empty or broken hulls are vacuumed up.
- Advanced camera systems inspect the almonds for imperfections and contaminants.
- Bursts of air remove identified imperfections and contaminants.
- Machines grade almonds based on shell conditions.
- Inspections are done to identify broken shells.
Packaging And Processing Almonds
Once the almonds have been sorted and inspected, they are ready to be packaged and processed. Technicians on a slow-moving conveyor belt conduct a final inspection, hand-picking any almonds that do not meet the strict quality standards. This ensures that only the perfect almonds make it through to the final stage of the process.
The almonds are then separated by size using a sieve-like conveyor belt, ensuring uniformity in each batch. Only the highest quality almonds are selected for further processing, while almonds with superficial chips or imperfections are sold to manufacturers who utilize them for various products.
Finally, the perfectly sorted and inspected almonds are carefully packed into large boxes, typically weighing up to 25kg. These boxes are then transported to other facilities where almonds are processed into a wide variety of products. These may include:
- Roasted and salted almonds
- Flavored almonds
- Sugared almonds
- Almond pieces for baking and cooking.

Frequently Asked Questions
How do they produce almonds?
Almond production follows a fascinating process that begins in late January when the trees emerge from dormancy. During this time, the almond trees undergo a phase called “bloom” where buds and flowers start to appear. To ensure the growth of almonds, honey bees play a vital role by pollinating the flowers. As the bees visit these flowers, they transfer pollen, allowing the buds to develop into almonds over time.
Where do almonds come from naturally?
Almonds have their origins in southwestern Asia, specifically in the Mediterranean climates between 28° and 48° N and between 20° and 40° S. This region is where the native tree, Prunus dulcis, is found and where almonds are naturally grown. However, California has become the leading producer of almonds, accounting for approximately 80 percent of the world’s supply.
Is An almond a tree?
Yes, an almond is the seed of the almond tree. The almond tree, scientifically known as Prunus dulcis, is a deciduous flowering tree appreciated for its delightful spring blossoms and tasty nuts. With its branches forming an upright and spreading head, the almond tree showcases an enchanting display of small pale pink or white flowers during late winter and early spring, creating an eye-catching sight before the leaves emerge. It is truly a remarkable tree that not only adds beauty to landscapes but also provides us with the delicious almonds we enjoy.
What makes an almond a nut?
While almonds are commonly referred to as nuts, they don’t meet the strict botanical definition. Almonds are actually seeds that come from the fruit of the almond tree. The almond fruit resembles a peach, and inside it contains the seed we commonly consume. Therefore, even though almonds are often grouped with nuts, they are technically seeds rather than true nuts.
