ABSTRACT:
A yeast trap device for use in making fermented beverages includes a trap container having a tapered neck portion through which a fluid conduit is inserted. A closure seal on the container neck provides an airtight seal around the fluid conduit. In use, a lower end of the fluid conduit is inserted into a container filled with a fermentable beverage mixture. The upper end of the conduit has a circumferential array of drain apertures spaced slightly below the upper open end of the conduit. The trap container has an open top portion which may be covered with cheesecloth or with a rigid airtight cover provided with a labyrinth airlock. During fermentation, yeast and contaminants are transmitted in a fluid suspension through the conduit and into the trap container. The carbon dioxide produced during fermentation exits through the open upper end of the conduit. Yeast and contaminant material are retained within the trap container and prevented from returning to the beverage mixture.
