Orchard to Table Olive Trees: Arbequina, Manzanilla, Picual, Koroneiki, and Kalamata
Olive trees have a rich history that spans thousands of years, deeply intertwined with various cultures and traditions. The cultivation of olives can be traced back to ancient times, particularly throughout the Mediterranean region. The olive branch itself has long been a symbol of peace, and olives hold great significance in mythology and religion.
In ancient times, the Mediterranean was the center of olive production. The region's mild climate and fertile, volcanic soil provided the perfect conditions for growing olive trees. The cultivation of olives was a part of the Mediterranean culture, influencing their food, art, and even their social and economic systems.
Olive trees are primarily found in regions with a Mediterranean climate, characterized by hot, dry summers and mild, wet winters. They require a minimum of 180 frost-free days per year to flower and produce olives. The optimal temperature range for olive production is between 20 and 30 degrees Celsius (68-86 degrees Fahrenheit).
Olive trees prefer well-drained soil with a pH level between 5.5 and 8.5. They can tolerate various soil types, including sandy, loamy, and even clay soil, as long as it is well-drained. The volcanic based soil of the region provides all of the mineral (including trace) required for optimal growth, still to this day. Adequate sunlight is also crucial for olive tree growth, so they are typically planted in areas with full sun exposure. Olive trees require at least 9 sunshine hours per day.
Olive tree varieties - Arbequina, Manzanilla, Picual, Koroneiki, and Kalamata
There are several olive tree varieties, each with its own unique characteristics and flavors. Five of the main varieties include Arbequina, Manzanilla, Picual, Koroneiki, and Kalamata.
Arbequina: The Arbequina olive tree, originating from Puglia, Italy, is famous for its distinctive characteristics that set it apart from other olive varieties. Recognized by its relatively small stature, this Arbequina is well-suited for growth in diverse environments, including both traditional field row agriculture and modern, intensive drip irrigation orchards.
The Arbequina tree is characterized by its hardiness and adaptability, able to thrive in various climatic conditions, though it prefers a temperate Mediterranean climate. Its leaves are small and dark green, presenting a dense and bushy appearance which contributes to its appeal as a landscape tree.
The olives produced by the Arbequina tree are small and round, with a deep green color that gradually turns to a rich brown or purple as they ripen. These olives are celebrated for their uniquely delicate and fruity flavor profile, which is less intense than that of larger olive varieties. This subtle taste makes Arbequina olives highly sought after for the production of virgin and extra virgin olive oil.
The oil extracted from these olives is typically mild, slightly sweet, and exceptionally smooth, with hints of almond, fresh grass, and a touch of peppery finish. It's this gentle yet complex flavor that makes Arbequina olive oil a favorite in dressings and marinades where its nuances can be fully appreciated without overpowering other ingredients.
Manzanilla: The Manzanilla olive tree, with its origins in Catalonia, Portugal, is a robust and vigorous cultivar, known for its resilience and productivity. It's a medium-sized tree, often with a sprawling canopy that provides quite a bit of shade, which is of benefit in a hot climate. The leaves of the Manzanilla are a vibrant green, larger and broader than Arbequina.
This tree grows best best in the warm, sunny climates typical of the Mediterranean region, although it has also adapted well to various other olive-growing regions around the world. The Manzanilla is particularly resistant to drought, making it a reliable choice for growers in dryer climates like the American southwest.
Manzanilla olives themselves are a true representation of Catalonia, Spanish olive heritage. They are medium in size, with a symmetrical, oval shape and a smooth, shiny surface. The skin of these olives typically starts as a bright green and transitions to a darker hue as they mature. Known for their slightly bitter yet rich and nuanced flavor, Manzanilla olives have a firm, meaty texture, which makes them particularly popular as a table olive.
They are often served whole or pitted, sometimes stuffed with ingredients like garlic, pimientos, or almonds, enhancing their inherent rich and complex flavor.
The balance of their slight bitterness with a savory depth makes them an excellent choice for a variety of appetites, from appetizers to main dishes, and they are also a key ingredient in many traditional Spanish recipes.
For successful application, a thorough surface cleaning is crucial, which involves cleaning both the metal and wood surfaces to remove any grease, dust, or debris. Sanding the surfaces can also increase the adhesive's grip, providing a stronger bond. In some cases, applying a primer to the metal can enhance the epoxy's adhesion.
After applying the epoxy, you should use clamps to hold the metal and wood securely in place until the epoxy cures completely. This step is critical because any movement during the curing process can weaken or even break the bond.
Gluing Wood to Concrete
Attaching wood to concrete surfaces requires an adhesive that can cope with the distinct characteristics of both materials. Polyurethane construction adhesive, particularly products like Loctite PL Premium, is highly recommended for this application due to its exceptional bonding strength and durability.
Koroneiki: The Koroneiki olive tree, native to Crete, Greece, is a variety that has gained widespread acclaim for its exceptional olive oil. This variety is characterized by its compact size, making it well-suited for growth in high-density orchards.
Despite its smaller stature, the Koroneiki is a prolific producer, known for its adaptability to various climatic conditions. Its leaves are small and narrow, with a silvery-green hue that adds to its beauty as a landscape tree. The tree thrives in the warm, dry climate typical of the Mediterranean and is highly resistant to drought, a trait that contributes to its popularity in regions with similar climatic conditions like Arizona.
Although small, they are renowned for the intense flavor they pack. These tiny olives, typically harvested while still green, have a high oil yield despite their small size. The skin of the Koroneiki olive is smooth and taut, encapsulating the rich, flavorful flesh within.
When pressed, these olives yield an oil that is favored for its rich, complex flavor profile. It is often described as earthy, with hints of herbs and a pleasantly bitter undertone. The oil is also known for its intense aroma. Because of these characteristics, Koroneiki olive oil is often sought after for fresh dressings and drizzles, where its full bouquet of flavors can be appreciated. It's a staple in Greek cuisine and is increasingly valued worldwide for its distinctive taste and high-quality.
Kalamata: The Kalamata olive tree, originating from Lesbos, Greece and specifically the region around the city of Kalamata, is the most popular olive. This tree is distinguished by its robust growth and large, spreading canopy. The leaves of the Kalamata are longer and slenderer than those of many other varieties, with a deep green color that complements the blackness of the olives.
This variety thrives in the warm and dry Mediterranean climate, displaying a proclivity to arid conditions. While it adapts well to various soil types, the Kalamata olive tree prefers well-drained, fertile, volcanic ash soils to reach its full production potential.
