It has to be fresh doesn't it? Due to having a 24 hour or so lifespan?
ECW had such a short lifespan, but is meanwhile expanded. EAW allways was longer lasting. Basicaly EAW and ECW starts to decay after a while - back to water.
Freshness is importand and has much to do with the quality of the activation since ECA water is only metastable (Back in the years it was like some weeks). Meanwhile the activation of the Swiss devices produces a very potent high quality product what is able to hold the load longer and decay slower, but remains metastable. Thats why it is produced fresh each time.
