8. Gluten free bread:

What is gluten free? Gluten free breads are a generic name for all breads that are free of the protein compound found in grain called gluten. Gluten is a protein that is responsible for the chewy and sticky compound so common towards dough. People go gluten free for a variety of reasons, whether due to allergy, celiac disease, or simply as a fad. Gluten is found in wheat and barley, and all wheat and barley derivative grains, such as spelt, rye, semolina, einkorn and other grains of that family. Oats are inherently gluten free although may be contaminated with gluten if not produced under proper supervision. A gluten free product simply means a product that does not contain those flours that have gluten and does not reveal the ingredients of the product which would make the difference regarding its blessing. A gluten free product can be made from a variety of flours. One can make gluten free bread using oat flour, which would make the bread Hamotzi, and one can make it using legume or seed flour [i.e. corn, millet, rice, amaranth, arrowroot, bean flour, buckwheat, coconut, nut, potato, quinoa, sorghum, soy, tapioca, teff]. One can also make the bread from a mixture of oat flour and other flours. The law of the before and after blessing on such bread depends on its flour ingredient, as explained below: 

Oat flour only gluten free bread: Gluten free bread that is made of only oat flour, without a mix of other flours, is Hamotzi and requires Birchas Hamazon just like any other bread.

Legume flour only [other than rice] gluten free bread: Gluten free bread that is made of only legume flour, without a mix of five grain flour, is Shehakol and requires Borei Nefashos.

Rice flour only gluten free bread:

Mixture of Oat and legume flour gluten free bread: If the bread is made of a mixture of legumes flour and oat flour, the before blessing is Hamotzi, even if the oat flour is the minority ingredient. [One is to wash prior to eating this bread. Regarding if a blessing is recited see above in A!] Regarding Birchas Hamazon, it depends on the amount of five grain flour included within the mixture, as well as on the amount that one ate. If the mixture contains enough oat flour that a Kezayis of it can be consumed within four minutes, and one indeed eats a Kezayis of oat flour within 4 minutes, then Birchas Hamazon is to be recited. If however one did not eat a Kezayis of oat flour within 4 minutes, then if the bread contains a Kezayis of oat flour within 174 grams of the bread, one is to recite Al Hamichyeah. If the bread does not contain a Kezayis of oat flour within 174 grams of the bread, then it is to only be eaten within a meal.
