Hey! I hope I am not posting this question in the wrong forum - but I thought the people here might use the same type of equipment as I. Can anyone tell me where to find a heavy duty, polypropylene measuring container/pitcher - for measuring concentrates by the oz.??? probably between the 128 - 155 oz. size??? I've only seen one (Wirthco) but it is not graduated enough to be accurate. Thanks for any ideas.
