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.
From The KIB: Pesach News – Avocado Oil and Spray
All Pure Virgin Avocado Oil & Spray (without additives), are fine for use on Pesach without a special Pesach designation on the label.
