Does anyone know if it would be permissible to drink Sake from this brewery?
I met one of the owners Brian and he invited me to stop by.

Additionally in general does Sake need a hechsher?
From the CRC:
Unflavored sake is acceptable without hashgacha.
Flavored sake (e.g., Coconut Sake) and sake which
states on the label that it was aged in wine casks
require hashgacha. Nevertheless, due to potential
kashrus concerns, it is preferable to only consume
premium sake labeled as Honjozo, Ginjo, or Daiginjo.
