Jenever (also called Genever) is a Dutch version of gin made in the Netherlands and Belgium. It is much like the grandfather of modern day gin. Jenever is flavoured with juniper, though it is distilled in a similar manner to whisky; from malt wine in a pot still.
Jenever (or Genever) comes in two styles two styles: old (oude) and young (jonge). Rather than being aged for different amounts of time, the two styles are dictated by distillation methods.
Oude Jenever must be distilled from at least 15% malt wine, with no more than 20g sugar per litre, whilst Jonge Jenever is made with no more than 15% malt wine, and 10 grams of sugar per litre. Jonge tends to be more neutral in flavour, whilst Oude Jenever is more like whisky, with a malty, woody and sometimes even smoky flavour.
