THE FRUIT

• young: Green• Ripe: Black/Purple• 50/60 flowers → 1 olive• Olive weighs 1-14 grams• 10-20% oil (yield) • On 1 tree: 0-800 kilos??• Approx 1-2 liter on 10 kilo olives

THE GROVE

• Milking (handpicking) (100 kg per day)• Mechanical stick ( 400- 900 kg per day)

PRODUCTION - HARVEST

• Shaker (10-15 sec per tree)• Super Intensive: ( a lot!)

PRODUCTION - HARVEST

PRODUCTION - TRANSPORT

• Within 24 hours• Ventilation• Wash & Deleaf

NOT THIS:

PRODUCTION EXTRACTION

Oldskool: Modern

There is nothing romantic about modern press. We need as less contact as possible with air to avoid the natural process of fertilization and solely extract the juice (oil).

PRODUCTION EXTRACTION

FILTER - NO FILTER?

”IT DEPENDS” on chemical and sensory profiles, quality of the initial oil, type of filter system and storage conditions.

PRODUCTIE - STORAGE

Oldskool: Now:

When oil is stored in open tanks or other Wanneer de olie in open vaten of andere oxidizing conditions the most valuable oxidants will ‘sacrifice” themselves to protect the

oil. That's why producers store their oil in dark stainless steel tanks away from air. ( done with nitrogen or argon )

EVOO CHARACTERISTICS

“Color means nothing on quality”1. Cultivar of olive2. Harvest timing (green or ripe)3. Exposure UV light, discolouration over time

SENSORY ANALYSIS

DEFECTS The main reasons for defects are the presence of "volatile particles" produced by "ripe fruits", oxidation of the unsaturated fatty acids, and / or attack by fungi and bacteria.

TASTING EXPERIENCE

“An appreciation of high quality oil is a matter of culture. ”

TASTING EXPERIENCE

Aroma of EVOO is formed by volatile particles

Aldehydes - C6 aldehydes:● Hexanal.● 3(Z)-Hexenal.● 2(E)-Hexenal

Alcohol:● Hexanol● 3(Z)-Hexanol● 2(E)-Hexanol

Aromatic and flavor componentsAcetyl esters:

● Hexyl acetate.● 3(Z)-Hexenyl acetate

FOODPAIRINGLight & Fruity oils: Delicate dishes

Medium sharp & bitter: Pasta’s, soups & salads

Intensive oils: Grilled, smoked food, fruits

FRAUDE/SELECTIONHow do you buy wine?

• Marketing, packaging, price?• Tasting sessions• Books, reviews (Flos Olei)

5 TIPS:• Dark packaging / cover• Harvest date• Type variety/blend• Look where it comes from• Google it!
