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 25mmx25mmx15mm. Each 1kg contains 108 pieces.
