Today's research topic: coffee beans are easy to be preserved by light roasting or deep roasting. To find this answer, we need to do an experiment: which is the longer exhaust time for light-roasted beans or deep-roasted coffee beans? As long as we compare the exhaust volume of coffee beans with different roasting degrees, we can know the amount of gas that coffee beans need to emit during preservation, and infer from the formula of exhaust = flavor loss that it is more difficult to preserve coffee beans with exuberant exhaust.

Compare two beans today:

The first one: before the second explosion, the bean gold Mantenin wet planing method G1

The second one: after 1 minute 45 seconds after the first explosion, the bean Yega Xuefeichel washing method G1

Two beans were baked at the same time in the same hour on the 24th.

It will be cooked on the 25th after an interval of 24 hours.

● here, let's put aside the cooking process and extraction effect, and simply look at which exhaust time is longer.

Divided into two groups:

Use the bean grinder BARATZA BG

Use steaming water temperature of 90 ℃

The amount of steam used is 35g ±1

The first group: fine grinding suitable for hand-punching range

Shallow baking Yega Shirley Fischer

Medium and deep baked gold Manning

The second group: rough grinding suitable for hand-punching range

1. Shallow baking Yega Shirley Fischer

two。 Medium and deep baked gold Manning

Steaming is to let coffee powder particles completely contact with water, fiber gap to absorb enough water, the gas will be discharged, more conducive to the later extraction and release of substances.

●, from the above, we can see from the timer

The light-baked Yega snow caffeine exhaled for longer, as if he didn't want to lose his life and kept breathing.

The deep Manning had already stopped his heartbeat and stretched out the gap to reach the maximum value of exhaust.

As the fiber of shallow baked beans is relatively tight, the fiber gap is relatively much less, and the diameter of the fiber gap is also much smaller, it takes longer to absorb water, and some places where the powder is denser will last longer.

The gap between the internal fibers of coffee beans will be looser and more and more as the degree of baking is deeper, because the expansion of beans will also break, and beans are more brittle, so the exhaust time of steaming will be earlier than that of shallow baked beans.

● Deep-baked Coffee beans Brand recommendation
