On the Saturday of Herri Eguna, at the start of the Errosaixuak festivities (the first weekend of October), Oñati turns its Herriko Plaza into an open-air cider house: txotx with more than twenty producers from midday, a custom now four decades old. Around it, a fair of crafts and farm produce, livestock, talos, a cheese contest, trikitixa and txistu.
