  喝白酒就得喝高度的,酒桌上经常听到有人这样说。那么到底是低度酒好还是高度酒好呢?记者近日通过专家了解了一些白酒度数的相关知识,给各位朋友科普一下。

  低度白酒是降度处理而来

  据记者了解,纯粮固态发酵的白酒,经过发酵以后要形成蒸馏,蒸馏的过程就是把度数提高的过程。粮食经过发酵后酿出的酒一般是十几度,十几度的酒经过蒸馏后,前期出来的酒可达80多度(称酒头)。掐头去尾,就是要去掉蒸馏两头,取中间部分,一般可达65度左右。真正成品酒度数是要经过不同批次、度数酒互相勾调确定的。

  由于低度酒不易保存,成品低度酒是高度酒通过降度处理(酿酒工艺中称“加浆”)而来的,并不是简单的加水兑的。也可以这样解释,低度酒往往都是高度酒经过进一步加工而成的。

  多少度的白酒喝得最顺口

  现行的标准白酒度数从低到高,一般有28度、33度、35度、38度、39度、40度、42度、45度、48度、50度、52度、53度、56度、60度、68度。

  经过无数专家多次品评后一致认为,酒分子和水分子之间的融合点在52度-54度之间,在这个度数的酒的口感是最醇和的,如果度数过高,会过于烈,过低则水的味道会过重,这也是多数名酒的常规度数都是52度、53度的原因,这些纯粮酿造的高度白酒则更加有利于收藏,时间越久越有价值。

  清香型白酒,其香味成分含量较少,酒度不宜降到过低,降到45度,便难以保持原酒风味,因此以50一55度为宜。浓香型与酱香型白酒,原酒中的香味物质较多且含量高,所以白酒度数降至38一40度仍能基本保持原酒风味,但一旦降至35度以下,就失去了我国传统酒固有的特色。

  我国出产的白酒中,曾有过73度的基酒,市面上很罕见。不过最烈的酒恐怕是一些自酿的粮食酒,度数最高可达75度,“度数高的酒由于没有勾兑东西,醉酒和醒酒都很快,贪杯对身体器官有害,建议大家少喝。”酒类专家说。

  优质低度酒对身体伤害小

  如今,健康的饮酒方法以及健康的白酒都受到广泛关注,保证健康饮酒的方法之一就是适量饮用低度白酒,可以将酒精危害降到最低,所以说,适量饮用低度白酒更有利于人体的健康,对身体的伤害要小一些。适量饮用低度白酒,可使饮用者血液中的酒精含量不至太高,减少对身体器官的刺激性。

  生产优质低度酒有四要素:高质量基酒、处理过的纯净水、除浊过滤、高质量调味酒调味。这一套流程下来,不仅要有技术,还要有设备,更要有专业的调酒师和丰富的调味酒。

  某些酒厂,往往在生产过程中偷工减料,比如:基酒降度后,添加香精香料;或者食用酒精加水降度,添加调味酒;更过分的是食用酒精加水降度,添加香精香料。现如今优质低度白酒生产门槛很高,劣质低度酒生产门槛却非常低。所以如果买到劣质低度酒对身体健康的危害更大。

  总之,喜欢喝酒的人,适量饮酒才能保证健康,喝酒时一定不要贪杯,过度喝酒对自己的身体是有害无益的。
