Genever is the juniper-flavored grain spirit of the Netherlands and Belgium — the malty ancestor that gin grew out of. But where gin is juniper-forward and dry, genever’s signature is malty, bready grain, with juniper only a background note.
Gin can stand in as a small juniper modifier, but not as the base — no gin has the malt-wine body of oude or korenwijn. A young jonge, or a soft Old Tom, is nearest in spirit.
London dry is neutral spirit redistilled with botanicals, juniper in front. Genever is built on malt wine, a distillate of malted grain closer to young whisky than to neutral spirit — pour dry gin into a genever recipe and the drink loses its grain body and turns lean.
Old Tom is a gin: neutral spirit, lightly sweetened. Genever predates gin and belongs to a different category altogether, so a recipe written for genever gains sugar and loses its bready weight.
"genever is just Dutch gin"
The other way round: it is the ancestor, not a variant. Gin in its place keeps the drink dry and juniper-led but takes away the grain weight genever is built on.
