Just souped 4 rolls of film at 1:1 and all the rolls came out perfect! The D76 was stored in a half full large dark plastic photo chemical jug. Room temp is around a chilly 58-60 degrees F.
I put mine in 750ml liquor bottles and have used it up to a year later. Those with a taste for Canadian Whisky (or is it Whiskey in Canada) will have a ready supply of brown bottles. Personally, my taste runs to bourbon and rye which are typically in clear bottles.
