It remains liquid for a long time, it may become turbid due to the presence of crystals but it hardly crystallises completely.
Colour from dark amber to brick, almost black.
Medium intensity smell and characteristic, very rich: balsamic, wood, resin, smoked and dull fireplace or burnt wood, wet dry leaves, also with references to animal connotations; also fruity, with fragrances of caramel, malt, dried apricots.
Slightly sweet, slightly to reasonably sour. Smell reminiscent of syrup and dates or panna cotta, fig jam, slightly savoury. Quite persistent.
