5、葡萄倒搭闷入盆子里加入白糖搅匀用勺子压破。

6、装入玻璃罐用保鲜膜封口。

7、在25-30度的室温里发酵1个月。

8、用干净消过毒的细纱布把葡萄酒过滤一下。

9、倒出,完成。

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。
主发酵期一般7天左右,发酵瓶最好要用水封的那种,这样发酵过程中产生的气体可以排除,另外看已经发酵了一周时间,尝起来有点甜,可能糖加多了喝发酵还不彻底。可以倒坛,把上面的葡萄皮以及下面的沉淀过滤掉,然后让其继续发酵。
发酵时产生的二氧化碳会将葡萄皮推到酿酒槽顶端,无法达到浸皮的效果,可用人工脚踩、机器搅拌或直接用回自动旋转的酒槽,让皮和汁能够充分混合,另外也有用泵将酒抽到酒槽顶端进行淋汁。
浸皮的时间越长, 释入酒中的酚类物质及香味物质森渗稿越浓。当酒精发酵完成,浸皮达到预期的程度之后,就可以把葡萄酒导引到其他酒槽,这部分成为自流酒。葡萄皮的部分还含有少量的葡萄酒,需经过榨汁取得。
扩展资料:
为保证葡萄酒质量,在葡萄酒酿造时,可采取人工添加不同的糖,定向改善葡萄汁的组成,也可采取浓缩葡萄汁和控制葡萄采摘时间的手段,提高葡萄汁中糖类、维生素、酚类、氨基酸等物质含量。
总之,在葡萄酒生产中,合理选择此孝原料糖并控制初始糖含量,对降低葡萄酒发酵过程中有害副喊和产物的生成以及提高葡萄酒的质量有着重要的作用。
