The invention relates to the technical field of
wine brewing, and discloses a preparation method of a
viburnum macrocephalum pulp sweet
white wine, which comprises the following steps: accurately harvesting
viburnum macrocephalum pulp grapes, simultaneously removing diseased fruits and green fruits, treating the picked
viburnum macrocephalum pulp grapes by adopting an air bag squeezing process, and then carrying out low-temperature clarification treatment to obtain grape juice. According to the preparation method of the viburnum macrocephalum pulp sweet
white wine, through low-temperature squeezing and special
yeast low-temperature
fermentation processes, the
retention rate of core
terpene aroma substances of the viburnum macrocephalum pulp is larger than or equal to 90%, the finished product is rich in
aroma, the attenuation rate of the
aroma within the
shelf life of 24 months is smaller than or equal to 15%, and the preparation method is far superior to a traditional process; the problem of low natural acidity of the Jones-dried
scallop pulp is solved, residual
sugar and acidity form golden balance, and the Jones-dried
scallop pulp is full in
sweet taste but not greasy; the
palatability score is improved by 50% or above compared with that of a traditional process; through oak
barrel aging
process innovation, the finished product can present various
flavor structures, the limitation of single
flavor of a traditional product is broken through, and the high-end attribute is remarkable.
