Ok Cotes Des Blanc can sometimes take 3 days to start fermenting, trust me, i use it a lot and even then there will be very little action. Youll have to stick your head in the bucket and listen for the sizzle like a soda pop. Get the temp to around 75* always to get started hough and then let it drop to the temp where you will be storing it. This lets it get started faster thus protecting your must from spoilage in the beginning until alc can start protecting it.
