For Jehovah's Witnesses, what are the ingredients to the bread and the wine? I am wondering what ingredients do the Jehovah's Witnesses use in the bread and the wine. I talked to one of my friends who is a active member of the Jehovah's Witness religion but was not satisfied with her answer.
To find a proper answer to this good question, have a look at their 12/15 2013 Watchtower magazine. The paragraphs 5-7, under the subtitle 'The Emblems' should interest you.

As a summary, the bread was made from wheat flour and water, without any leaven or seasoning, such as salt, being added. Because it was unleavened, it would not have risen.

[UPDATE] They recently edited a video on how to make the bread : How to Make Memorial Bread

For the wine, as there was no need for augmenting or fortifying the value of Jesus’ blood, the wine used is not a type fortified with brandy or spices. Plain red wine should be used, a homemade wine or a commercial wine, such as Beaujolais, Burgundy, or Chianti.
