======================= *Islamic Questions & Answers* Darul Iftaa Canada with Mufti Faisal al-Mahmudi (fatwa.ca) ======================= *Sharing Link:* https://qna.ilmhub.com/question/will-such-milk-be-halal-if-brewers-spent-grain-is-used-to-make-milk/ *Question:* As per this link brewers spent grain is being transformed into vegan milk or even leather. https://www.bbc.com/future/article/20250206-how-brewers-spent-grain-is-being-turned-into-vegan-barley-milk-leather-and-cakes 1. Would such milk be halal suitable for consumption? 2. Would the leather made from this process be pure? *Answer:* *Bismillahi Ta'ala* *Walaikum Assalam Warahmatullah,* At the outset, we establish the *shar‘ī* distinction between *khamr* and synthetic alcohol. *Khamr* refers specifically to fermented substances derived from dates or grapes. In contrast, alcohol from all other sources is classified as non-khamr (or, for our terminology, synthetic alcohol). Secondly, we note the primary *shar‘ī* rulings derived from the Qur’an concerning *khamr*: a. It is *harām* for consumption, even in small quantities. b. It is *najis* (impure) with a status of *ghalīẓa* (severe impurity). However, *non-khamr* alcohol is governed by different rulings: a. It is *harām* for consumption only when: - It is used for intoxication. - It is consumed in vain or for futile purposes. - It is consumed in a quantity that leads to intoxication. b. It is *not* considered *najis* (impure). For further details on the use of alcohol in products, you may refer to our blog posts: [https://ilmhub.com/?s=alcohol]. *BSG: Brewer’s Spent Grain* During brewing, malted barley is mashed to extract fermentable sugars, leaving behind the solid residue known as *Brewer’s Spent Grain* (BSG). This material does not undergo fermentation; rather, it consists of the leftover grain husks and other components after the sugars have been extracted. Thus: 1. *Milk made from BSG mulch* is *Halal Suitable* since the grains are not fermented and do not contain alcohol. Even if fermentation were to occur, it would not be a concern, as it would fall under *non-khamr*. 2. *Leather made from BSG mulch* follows the *non-khamr* ruling regarding purity. Therefore, such leather is *Halal Suitable* for use. *Wallahu A'lam* *And Allah Ta’āla Knows Best* *Mufti Faisal al-Mahmudi*
