I would suspect that homebrewing is illegal in Jordan as it is in many other Muslim nations. Certainly you will find out when you try to import any products such as malt, yeast, etc. they'll probably get confiscated by Customs if the making of beer at home is not legal. Perhaps before you try importing any and risk confiscation, you should check if the products are locally available. The availablility (or absence thereof) of brewing ingredients would be a fairly clear indicator of the legality of homebrewing in Jordan.
