It's made by Antonio Vence, a hobbyist txakoli producer turned vermouth producer out of Bizkaia. The guy is a total amaro-head, so he set out to make a fortified wine with his txakoli that would be popular in the area. Though txurrut is a pretty classic spanish sipping vermouth, some worm-woody bitterness in txurrut is a clear nod to amaro.
