Rose summer, as the most outstanding variety of coffee, is very popular with coffee lovers. Among them, the rose summer treated with water can best highlight the flavor characteristics of the rose summer itself. Rose summer is special in that it has very obvious and clear floral and citrus flavor, very high cleanliness, soft and elegant acidity, long-lasting cotton sweetness, and the taste of high-grade black tea.

To fully show these qualities, you have to work on baking. Rosa rugosa is generally planted at a high altitude of more than 1500 meters, which is a kind of beans with high hardness and high density. Its shape is full, medium particle size, thick and long bean body, pointed at both ends.

This time, take the blue label rose summer of the jadeite manor in Panama as an example to see how to express the unique flavor of rose summer through baking.

The idea of baking is that because of the high hardness and density of beans, a large fire will be used to dehydrate in the early stage, and the temperature difference between the bean surface and the bean core will be quickly established. In order to have more fragrance of flowers, Maillard's reaction time is relatively short, so after turning yellow, it will adjust the fire to medium to high, quickly let the beans into an explosion, and shorten the period from yellowing to the beginning of the explosion can also increase cleanliness. The temperature rises too quickly after an explosion will aggravate the caramelization reaction and grind off the aroma of flowers and fruits, so it will greatly reduce the fire after entering the explosion, pull the low temperature to rise, and the throttle will be fully opened at the beginning of the explosion. Drop the beans at the end of a dense explosion to let the bean core develop and mature with the most residual aroma and sugar.

This baking uses Taiwan Yang family 800n semi-direct fire roaster, the maximum baking capacity is 500g.

Amount of beans: 300g

Speed: 60 revolutions per minute

The start of the explosion: 181.8 degrees @ 7 minutes 52 seconds

Exit point: 190 degrees @ 1 minutes 28 seconds

Fire throttle adjustment:

As a result of the cup test, the entrance acidity is delicate and soft, and sweetness soon appears on the tongue and lasts for a long time. The taste is clean and bright, like black tea. There are aromas of jasmine, honeysuckle, grapefruit, lemon, black tea and sugar. The level is clear and the rhyme is long.

In the process of baking, it should be noted that the curve of rose baking should not be too long, otherwise the flavor will be rigid. After an explosion, the temperature rise should not be too high, the two ends of Rose Summer are sharp, it is easy to have a black focus of less than 6 degrees temperature rise will be better.
