Kava-kava General Question

[Rob290482]

I Rob is new to this and would like a bit of advice.

He has managed to find a supplier who will send Kava root powder to the UK for quite cheap, but is a bit worried about how much is required to get the nice effect.

He read on the web that between 14-28g powdered root mixed in water (and massaged in a net bag for 30 min or so) is ideal.

He doesnt want to drop to sleep, but again doesnt want to waste a load of powder.

If he puts 70g Kava powder in a bit tub containing just over 2 litres and let settle for 30 min, then do the massaging in netting etc... would this result in a good drink? Also how long can this drink be stored (in the fridge i assume)

Thank you
