Hand-Roasted Coffee to order.

Craft of roasting

At ZOIS Coffee Roasters we know that roasting is a skill that can be taught but it takes years of experience to master.

Roasting is a very complex process in which many changes occur continuously and throughout the coffee batch.

The experience in roasting helps us to achieve, batch by batch the desired roast profile.

The way in which air circulation and heat is applied will significantly influence the sensory perception of flavour and taste in coffee.

Different climate conditions and origins of the coffee bean require different roasting parameters which an experienced roaster can apply.

All ZOIS coffees you buy from our website are Hand Roasted to order .

Colour change of coffee bean from Green to Roasted coffee.


Types of Roasts

Light Roast: This type of roast is light brown in colour and preferred for mild bodied coffees.

The light roasted coffee beans have no oil on the surface because they are not roasted enough

for the oils to break through to the surface. AKA: City, Cinnamon (relates to the colour)

Medium Roast: This type of roast is medium brown in colour with a non- oily surface and

it is the most preferred type of roast in the United States. AKA: City, American

Medium-Dark Roast: This type of roast is dark brown in colour and has an oily surface and a slight bittersweet aftertaste. AKA: Full City

Dark Roast: This type of roast produces nearly black and oily beans with a pronounced bitterness.

The darker the roast, the less acidity will be found in the cup and it is the most popular roast profile in Europe;

Our mission is to change this by introducing higher quality coffee with lighter roasted profiles

where consumers can taste more flavours and aromas in their cup. AKA: Italian, French,Viennese

Much more information about roasting can be found in the book of Scott Rao,The Coffee Roasters Companion and websites of quality roasters

About the Green

Coffee bean before being roasted has a Green colour; not brown, dark brown, or black, just Green

How it was discovered- As usual by accident!

The popular theory is that coffee was really ‘discovered’ by a sheep herder from Caffa Ethiopia. The herder was known as Kaldi, and he happened to notice that his sheep would get hyperactive after eating red “cherries” from the plant we now know to be coffee.

Intrigued as to what the plant was doing to his flock, Kaldi tried a couple himself, and was soon in a caffeine frenzy. Initially, the local monks scolded Kaldi for his new found drug, but they soon found that if they took some coffee themselves, the monks could stay up later for their prayers- or so the story goes.

By the 15th century, coffee was being grown in the Yemeni district of Arabia and by the 16th century it was known in Persia, Egypt, Syria, and Turkey.

Coffee was not only enjoyed in homes, but also in the many public coffee houses — called qahveh khaneh — which began to appear in cities across the Near East.

Papal approval

When this beverage came to Europe, some people reacted to this new beverage with suspicion or fear, calling it the “bitter invention of Satan.” The local clergy condemned coffee when it came to Venice in 1615.

The controversy was so great that Pope Clement VIII was asked to intervene. He decided to taste the beverage for himself before making a decision, and found the drink so satisfying that he gave it papal approval.

By the 15th Century,coffee was being grown in the Yemeni district of Arabia and by the 16th century it was known in Persia,Egypt,Syria and Turkey.

In 1714, the Mayor of Amsterdam presented a gift of a young coffee plant to King Louis XIV of France. The King ordered it to be planted in the Royal Botanical Garden in Paris. In 1723, a young naval officer, Gabriel de Clieu obtained a seedling from the King’s plant.

Gabriel managed to transport it and plant it to Martinique where it spread over the next 50 years and its parent of all coffee trees throughout the Caribbean,South and Central America.
