There have been various fatwas regarding the status of coffee and caffeine as being halal according to Islamic scholars. Anything which does not cause inebriation or harm, including caffeine-containing drinks such as coffee and tea. Wine coffee however cannot be considered halal due to containing words related to wine which are forbidden within Islam.

Are decaf coffees halal? Yes, as long as they come from certified brands. Most companies that manufacture coffee use the Common Code for Coffee Community (4C) certification which meets all halal-friendly criteria and is issued by an impartial third-party organisation that certifies it accordingly.

This involves carefully cleansing and processing coffee beans before extraction, free from ingredients such as pork fat and meat, as well as treating civets used for extracting luwak coffee with care; consequently, the Indonesian Ulema Council issued a fatwa declaring this coffee halal – this statement also applies to other forms of civet-sourced coffee such as kopi sireng and tubruk coffees derived through this source.
