In the process of making roasted coffee beans, many coffee manufacturers use oak barrels in the process of roasting coffee beans, which will absorb all the smell around them. In order to avoid absorbing odors, coffee producers generally take two ways to solve this problem. One is to roast coffee beans quickly, and the other is to turn miscellaneous flavors into ideal aromas. Many coffee producers prefer the latter because the flavor of coffee can be sublimated.

Put raw coffee beans into various oak barrels to absorb the unique aroma of old oak barrels.

Rum oak barrel

Known as the "wine of pirates", rum is made from sucrose and aged in oak barrels. The remaining rum flavor in the oak barrel is a perfect combination of the bitterness of the coffee itself, making the final coffee with attractive aromas of raisins, caramel, toffee and spices.

Whisky oak barrel

Whisky wines passing through oak barrels have aromas of caramel, vanilla and wood. Similarly, such an attractive aroma can also be found in coffee beans. After the whisky wine is aged in a barrel, the coffee beans can also be put into the barrel to give off the unique aroma of whisky.

Earlier, Starbucks put a batch of selected Sulawesi beans in oak barrels provided by Woodinville Whiskey, a local spirits distiller in Washington state, and then roasted after weeks of ripening.

It's time to "brew" coffee in oak barrels. Whisky barrel aging technology has been widely used in the production of wine, beer, gin and even chocolate, and coffee may be the next popular drink affected by this technology.

The process of making aged coffee is like this: unroasted coffee beans are placed in used wine or spirits barrels and fermented for several weeks, during which time manual stirring is required to ensure that the surface of the coffee beans is in contact with the inner wall of the barrel.

The aroma of the original wine or spirits in the barrel is transferred to the coffee beans, which are roasted to remove the alcohol, while giving the coffee beans a "mixed soil and oak aroma" that the traditional baking process does not have. It is reported that Starbucks uses 800 pounds of Sulawesi beans at a time to get the taste of whiskey.

What are old coffee beans?

Old coffee beans do not mean that coffee beans are not allowed after they have been kept for a long time, because coffee beans will rot after they have been kept for a long time, changing from fresh cyan to white, then to yellow, becoming dull, and even growing worms. Like aged wine, raw beans must be properly processed and stored for a long time before they can be called real aged coffee.

Where should the aged coffee beans be stored?

Aged coffee beans should be stored in the country of origin and stored in high and cool warehouses so that ripe beans can "grow" again after harvest. In order to ensure the quality, the farm owner must also take care of it from time to time, turning over a bag of sacks from time to time, so that each side of raw coffee beans can be evenly exposed to air and water.

Third, how to store old coffee beans?

It should be stored in the inner peel. If the endocarp is removed, the raw beans will lose protection and deteriorate.

What is the flavor of the old coffee?

After aging treatment, the acidity of coffee beans becomes weaker, but the mellow degree becomes higher, the texture becomes thicker, and there is a kind of mature and serious feeling, which is very different from the lively and bright new beans. Roasted old coffee beans take a long time to develop before they appear full-bodied, so it is recommended to start drinking it 3 days later. Strictly speaking, the aged beans on the first day after baking have no special flavor.

What kind of coffee is suitable for old coffee?

Aged coffee is rich in consistency and is suitable for blending with other coffee with excellent acidity or special aroma. In this way, it can make some special coffee thicker. Some of Starbucks's mixed coffee is mixed with old Sumatran beans.

Ps: old coffee is not easy to store and is very precious. As the old coffee contains the farm owner's long-term commitment and painstaking efforts, it usually needs to be stored for 3-5 years, so it is very precious.
