    散裝白酒味道發苦是什么原因造成的?

    原輔料不凈或挑選不當發生的苦味:運用資料霉變,曲粉蛻變,輔料稻殼未清蒸或清蒸不完全或霉變;運用含脂量高的資料;散酒加盟運用含單寧高的資料等,用于釀酒出產,所產的酒均有苦味或霉味和其他邪雜味,主要是釀酒用的原輔料被有害微生物污染,資猜中的高脂肪被氧化,在進程中被分成某些酚類化合物所造成的。

    Bitterness caused by unclean raw and auxiliary materials or improper selection: mildew, Qu powder metamorphosis by using data, rice husk of auxiliary materials is not steamed or steamed incompletely or mildewed; Use data with high fat content; Bulk liquor uses materials with high tannins for brewing production. The produced liquor has bitter or musty taste and other evil and miscellaneous flavors, which is mainly caused by the pollution of raw and auxiliary materials for brewing by harmful microorganisms, the oxidation of high fat and the division into some phenolic compounds in the process.
    別的原輔料皮殼中含有較多的多縮戊糖。在微生物的效果下會生成帶有焦苦味的糠醛;多縮戊糖在高溫下蒸煮也會發生糠醛等,都是給散白酒帶來苦味物質的原始條件。配料不合理:稻殼用量過多,用水量過大或過少,用曲量過大或用劣質曲、新舊曲分配不合理。
    The shell of other raw and auxiliary materials contains more pentosan. Under the effect of microorganism, furfural with scorching and bitter taste will be produced; Baijiu can also produce furfural when cooking at high temperature, which is the original condition for bringing bitter substances to bulk liquor. Unreasonable ingredients: too much rice husk, too much or too little water, too much koji, or poor koji, and unreasonable distribution of new and old koji.
    御賢坊散裝酒加盟告訴您:填充料運用過多,窖內空地大,酵母繁衍過量、酵母自溶后生成酪醇并影響酵母效果,若酪醇含量適中,可使白酒具有愉快的芳香氣味,味感豐盛;若含量過高則會苦味嚴峻,用曲量大酒醅中蛋白質含量高,時必發生許多的酪氨酸,經酵母效果脫氨、脫羥而生成酪醇多,則導致酒的苦味。
    Our Baijiu bulk wine tells you: the filling material is too much, the cellar is empty, the yeast is overgrown, the yeast is self dissolved, the tyramol is formed and the yeast effect is affected. If the tyramol content is moderate, the liquor can have a pleasant aroma and a rich flavor. If the content is too high, the bitter taste will be severe. If the amount of starter is large and the protein content in the fermented grains is high, a lot of tyrosine will occur. After deamination and hydroxylation by yeast, more tyrosol will be generated, which will lead to the bitter taste of the wine.
    出產工藝條件控制溫度不合理:入窖溫度高或糧食、曲粉損壞過細或過粗,窖池密封不嚴,密封窖泥開裂并長霉,酒醅堆積時刻過長等都會使酒時發生倒燒味、苦味、辛辣味、霉味等。入窖溫度高、前期溫度不易控制,然后構成前期升溫過猛、糟醅品溫高、繼續時刻長。
    The control temperature of production process conditions is unreasonable: high pit entry temperature, too fine or too coarse grain and starter powder damage, lax pit sealing, cracking and mildew of sealed pit mud, long accumulation time of fermented grains, etc. will lead to backburning taste, bitterness, spicy taste, mildew taste, etc. It is difficult to control the temperature in the early stage due to high pit entry temperature, and then it forms excessive temperature rise in the early stage, high temperature of fermented grains and long continuous time.
    溫度高,有利酵母對氨基酸的脫氨,酒醅溫度高,酵母變老自溶快,自溶后發生的氨基酸及酪氨酸都會導制高等級的醇、酪醇含量的增加。然后發生的白酒帶有嚴峻并耐久的苦味。
    High temperature is conducive to the deamination of amino acids by yeast. High temperature of fermented grains makes yeast age and dissolve rapidly. The amino acids and tyrosine after autolysis will lead to the increase of high-grade alcohol and tyrosol content. The Baijiu liquor then has severe and persistent bitterness.
    溫度過高,發生的甘油易被酵母分成丙烯醛,丙烯醛有繼續性的苦味并刺激性強。若酒醅堆積時刻較長,侵入的雜菌也就多,甘油的分更快,發生了苦味。蒸餾時,前期用汽過大,將會發生焦鍋現象,使焦化物質帶入酒中,發生不良的焦苦味。
    When the temperature is too high, the glycerol produced is easy to be divided into acrolein by yeast. Acrolein has continuous bitterness and strong irritation. If the accumulation time of fermented grains is long, there will be more invasive miscellaneous bacteria, faster glycerol separation and bitter taste. During distillation, if the steam is used too much in the early stage, coke pot phenomenon will occur, which will bring coking substances into the wine and produce bad coke bitterness.
    一起前期的火汽大還將把其它邪雜味帶入酒中。大多數苦味物質成分的沸點都較高,酒尾部分含量較多。丙烯醛一般酒頭較多,雜醇油酒尾居多。然后蒸酒時一定要“量質摘酒,掐頭去尾”。
    Together with the fire and steam in the early stage, it will also bring other evil and miscellaneous flavors into the wine. The boiling point of most bitter substances is high, and the content of wine tail is high. Acrolein generally has more wine heads and fusel oil wine tails. Then, when steaming wine, we must "pick wine by quantity and quality, pinch the head and remove the tail".
