These are hard pressed, very dense premium charcoals. Al Duchan® is a long-established, very popular German brand and recognised as one of the best coals on the market.
No taste, no odour (only some minimal odour the first few minutes when lighting up the coal as with every charcoal), minimal ash. Burns very hot and long. Size 40mmx30mmx25mm. Each 1kg contains 36 pieces.
