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 26mmx26mmx26mm. Burns 2h and longer. Each 1kg contains 64 pieces. Recommendation is 4 pieces for hot scree, 3 pieces for Provost or HMD, 3 pieces for foil setup on medium-large bowl, 2 pieces for small heads like 80FT80 or similar.
