This invention discloses a method for preparing rum with high total ester content. The method includes the following steps: pretreating molasses; preparing a first fermentation medium using the pretreated molasses; expanding the culture of fissile yeast seed liquid in the first fermentation medium to obtain fissile yeast fermentation broth; continuously adding the pretreated molasses to the fissile yeast fermentation broth, culturing to obtain a fermentation product, wherein the residual sugar content of the fermentation product is controlled at 0.5-2%; preparing a second fermentation medium using the pretreated molasses; inoculating the fermentation bacteria into the second fermentation medium, culturing to obtain a fermentation broth; the fermentation bacteria include at least one of Clostridium acetic acid and Acetobacter pasteurella; adding the fermentation broth to the fermentation product, culturing to obtain a mash; continuously distilling the mash, using a kettle heating method for three-part distillation, mixing the second fraction with oak shavings, and aging; obtaining the base spirit, which is then blended to obtain rum with high total ester content. This method can produce mash with high alcohol content and high ester content in a short time.

The scheme discloses a mildewy dregs treatment method in the technical field of brewing, which comprises the following steps: step one, using hot water above 95 DEG C to disinfect and kill the mildewy dregs with 95 DEG C; step two, putting the disinfected and killed mildewy dregs into a retort to steam for 20-40 min, taking out the steamed mildewy dregs to spread and air, to thresh, and to fold after the mildewy dregs are cooled; step three, putting the folded mildewy dregs into the retort to steam for 20-40 min after 5-8 h, taking out the steamed mildewy dregs to spread and air, to thresh, and to fold after the mildewy dregs are cooled; step four, repeating the operation of step three for 1-3 times to obtain the treated mildewy dregs. Through the mildewy dregs treatment method, the mildewy dregs can be effectively removed, and the mildew can be completely killed.
