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 invention belongs to the technical field of wine brewing, and relates to a method for judging that a saccharification pile reaches a high-yield wine pile turning standard. According to the distinguishing method, the saccharification heap is distinguished to reach the high-yield wine turning standard according to the stacking fermentation indexes of the saccharification heap, and the stacking fermentation indexes comprise the saccharification heap top temperature, the saccharification heap bottom temperature, the saccharification heap medium temperature and the like. The method comprises the following steps: (1) obtaining modeling characteristic data; (2) sorting model data feature importance; (3) screening and combining modeling data; and (4) constructing a saccharification pile high-yield wine turning standard judgment model and predicting. The method provided by the invention has more comprehensive stacking fermentation indexes for saccharification piles in the high-temperature stacking process, and is also more scientific and reasonable. According to the method, the pile turning condition of the saccharification pile in the pile fermentation process is evaluated through the model, and whether the state of the saccharification pile meets the pile turning standard of high-yield wine or not is judged based on the model, so that the stable and high-yield wine yield is achieved.

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.
