Don't ignore odour (of anything)... that's our bodies warning system. It's easy to tell if it smells right... snif then ask "does that smell offend me?". If the answer is yes, pour it out. If no, bottle it and put it in the fridge. Don't forget it doesn't last forever...(I wont drink it if it's over a week old).

Blending? Blending is just a method I came across through trial and error. Other methods work, but blending is really easy.
