Large mutation Maragogype ·From Typica.

·This mutant plant is taller than normal coffee in all characters, but lower in yield.

·The genetic factor is a pair of dominant Mg, and the progeny of normal coffee are large, but the yield is higher, so they are often used as rootstocks and hybrid parents.

Small Mutation Mokka

It evolved naturally from bourbon in Yemen and later spread to Reunion Island, where it was transplanted to Brazil, Hawaii, Guatemala, and Colombia. This mutant has short plant, small leaves, large glands, small fruit, naturally small bean shape (bean width 0.39--0.43 cm) and round, but good quality, low yield. Small mocha also has small round (male) beans, but the proportion is only 2%, far lower than the average Arabica 5- 10%.

After arriving in Hawaii, the small mocha was crossed with Typica by the research unit and became a tall mocha to adapt to the terroir of Maui Island in Hawaii, but the bean shape still maintained its original cute appearance. Guatemala or Colombia mocha may be from Brazil or Hawaii, retaining the original dwarf characteristics if from Brazil, or modified tall mocha if from Hawaii.

The genetic factors were two pairs of factors, one pair was the complete recessive factor lrlr of coffee law (pointed bourbon) mutation, and the other pair was the complete recessive factor momo.

Mokka was originally a place name, now a taste, and perhaps a scientific revolution in the future.

Mocha used to be one of the most sought-after coffee beans in the world. The name mocha coffee originated from the yemeni town of mocha on the red sea coast. This region monopolized coffee exports in the 15th century, especially in the Arabian Peninsula. This particular coffee bean is now known as Arabica and still grows in the hills of Yemen.

It's from Muha, a now-abandoned port.

Although production rose and prices fell, the coffee remained expensive.

Expensive, and hot.

Arabica coffee has been grown in a wider area, but Yemeni varieties are available.

It can still be the most delicious. Just like grapes, these crops suck from the soil

take nutrients and create a unique flavor that is difficult to replicate elsewhere.

It's over.

Now mocha history has taken a new turn. In 2004, a type of Arabica coffee grown in Ethiopia was found to contain far less caffeine than other types of coffee. Generally speaking, coffee flavor is lost by removing coffee, so this natural decaf coffee bean is very exciting. A chemical in coffee beans called theobromine (also found in cocoa beans) is added a methyl group to make caffeine: this chemical process is called methylation. However, in this coffee bean, this process seems to be limited. Scientists are trying to transplant similar traits into other species. So maybe one day mocha will mean high-quality decaf coffee.
