Who drank Thebana in 1972?

You drank the 1982 Lafite, but have you ever drunk the 1972 Tiberna? In the technical archives of Zhangyu Company, there is a research report completed in 1976, "Isolation and Application of Wine Yeast", which mentions the "Xiebaina Red Original Wine" in 1972 and 1973, which is one of the "red raisin wines" in the "5 red and white raisin wines" of the research subjects, that is, "dry red wine".

The authors of the study are signed as "Yantai Grape Wine Company Laboratory". The so-called "Yantai Grape WineMaking Company", that is, the company name used by Zhangyu Grape Winemaking Company since 1966, was restored to its original name in 1982. The foreword to the report reads: "From the grape season in 1972 to the grape season in 1974, in a three-year period, we isolated 163 yeast strains from 27 grape varieties and 5 red and white raisin wines grown in different regions, and identified their fermentation capacity and aroma properties one by one. Five promising strains of wine yeast were selected. Small tests and medium-sized tests believe that the selected strains have their own characteristics, in line with the needs of wine and brandy, and some strains have been applied to brandy production, which improves the quality of products. ”

One of the tables in the report, "Separation of Yeast from Different Grape Varieties and Dry Wine", shows that the red grape varieties of the 27 grape varieties include Snake Dragon Ball, Cabernet Sauvignon, Cabernet Franc, etc.; white grape varieties include Riesling, Qiong Yao Pulp, Guiren Xiang and so on. The "5 red and white raisin wines" include "Riesling White Plains", "Longan White Plains", "Vermes original wines", "Xie baina red original wines", and another "red original wine" without specifying a specific name. The "original wine" in the report, taken from "dry wine in the post-fermentation period", said: "There are also many excellent wine yeasts in the dry wine of the post-fermentation period. Therefore, we also list dry wine as the object of selective sampling. Among them, the number of yeast strains isolated from "Xie Bai Na Red Original Wine" in the laboratory in 1972 and 1973 was 3 strains each.

The laboratory selected "5 more promising wine yeast strains", the strain numbers are 7318, 7329, 7448, 7480, 7510, the first two digits in the number 73, 74, 75, representing the completion of the identification time in 1973, 1974, 1975. The report details the aroma properties and characteristics of each strain, and indicates which type of wine is suitable for fermentation. According to the report: "Wine yeast has a certain dependence on grape varieties. In general, good grape varieties can isolate better wine yeast strains. For example, Cabernet Sauvignon is a famous grape variety at home and abroad, and we have isolated a very ideal yeast strain on this grape variety for two consecutive years. ”

The main chapters of the report are "Isolation and Selection of Strains" (including "Selection sampling", "Isolation Method", "Strain Selection"),"Screening and Identification of Strains" (including "Basis for Screening and Identification", "Screening and Identification Work in 72 Years", "Screening and Identification Work in 73 and 74 Years", "Characteristics of Selected Strains")," "Application of Selected Strains" (including "Application to Wine Fermentation", "Application of Single Strains to Proto-Brandy Fermentation", "Combined Application of Two Strains", "Combination Application of Two Strains", "Application of Two Strains", "Identification of Two Strains", "Identification of Strains", "Identification of Selected Strains", "Identification of Selected Strains", "Identification of Selected Strains", "Identification of Selected Strains", "Identification of Selected Strains", "Identification of Combination of three strains applied"). This study not only reflects the scientific research level of Chinese winemaking researchers in the field of yeast isolation and application in the 1970s, but also records the existence of Xie Baina and Riesling in 1972 and 1973, respectively, dry red wine and dry white wine.

More importantly, the study's account of Xie Bai Na and Riesling means that the history of Zhangyu Company's production of Xie Bai Na dry red and Riesling dry white has been accurately recorded in the original literature in each of the 10 years of the 1930s, 1940s, 1950s, 1960s and 1970s. This once again confirms that the so-called "China's first bottle of dry white was born in 1976" and "China's first bottle of dry red was born in 1983" and other statements, which are pure nonsense that ignore history.
