需要发酵1个月,具体做法如下:
需要提前准备好的材料包括:紫葡萄2500克、白糖300克、盐10克、面粉100克。
1、买回来的葡萄先把有破损的挑选出来。

2、把葡萄放进一个大些的盆子里加入清水和适量面粉,用手顺着一个方向搅拌清洗。

3、洗净灰尘的葡萄再用淡盐水浸泡15分钟,清除表面残留农药。

7、在25-30度的室温里发酵1个月。

注意事项:
葡萄必须是红的发紫的才行,发青的做出的口感很差的,白糖比例看个人喜欢口感。
自酿葡萄酒不限制时间,随时都可以喝。酒酿好以后,稍微放的时间长一点,可以使葡萄酒更澄澈透亮。

扩展资料
将葡萄和白糖按一定比例放到到器皿中发酵,过一段时间就可以尝到味道甘醇的自酿葡萄美酒,不仅成本低,而且操作方便。喝红酒能保健,是指干红葡萄酒。干红里面含有很多酚类物质,具有抗氧化、通血管、降血脂的作用。
单宁等酚类物质,主要存在于葡萄皮和葡萄核中,家庭自酿葡萄酒时提取出的酚类物质非常有限。此外,葡萄酒的酿造是把糖转化成醇的过程,规范地酿造葡萄酒是去除一部分糖,而自酿葡萄酒不仅没有去除糖分,反而通过加糖来增加甜度和酒精度,按照葡萄酒国家标准对酒精度大于7%的要求,在酿造葡萄酒过程中有必要适量加一些糖,以保证酒精度达标,但过量加糖毫无必要,对特定人群还有害。
从化学的角度来说,无论是自酿葡萄酒还是别的酒,只要是自酿酒想要降低其甲醇都可以选择加热的方式。从食品安全角度,自酿葡萄酒一定要严格挑选原材料,酿制容器要做好清洗、消毒工作,严格控制酿制过程的卫生状况。只要是卫生状况良好、没有被污染、无变质、无有毒有害物质、甲醇没有超标的自酿葡萄酒,可以适度饮用。
网易新闻--自酿葡萄酒可以放心喝吗
一般一次发酵20天,2次发酵15天,一共35天左右!不过我还是不建议你饮用自酿的葡萄酒,
自酿葡萄酒含有不同浓度的甲醇和杂醇油。甲醇、杂醇油的产生主要来源于原料。一方面,葡萄皮中的果胶在果胶酶或热能的作用下分解出甲醇,霉变也会产生大量甲醇,酵越彻底,甲醇含量会越高;另一方面,葡萄中的蛋白质水解为氨基酸,再经过酶的催化作用生成杂醇油。
此外,自酿葡萄酒的发酵过程中会产生大量的气体,所以不要用塑料瓶、不锈钢、铝器皿等来盛装,以免发生化学反应
自己酿造葡萄酒虽然实惠,但是目前,大多数家庭酿制葡萄酒过程还没有除去甲醇和杂醇油的工艺,在自行酿制和饮用时应该当心,避免此类有毒、有害物质对身体造成危害。
