Roasted Walnut Oil: How long will it keep?

Just picked up some roasted walnut oil at Whole Foods and am now concerned that it will go rancid before I can use the whole thing. How long will this last if kept in the fridge?

  1. anywhere from 2-6 months, though the quality & flavor will begin to deteriorate before it goes rancid. usually best to use within a few months.

    1. Don't keep it in the door - rather, the lower rear (coldest area) or the freezer.

      1. The stuff is so special and expensive and doesn't keep. I've resolved the next time I need some to take the rest of the bottle and divide it into smaller bottles for friends. (Hopefully they will do the same when they have some toasted nut oils!) Better than letting it spoil.

        1. I've kept a container of La Tourangelle for over a year in the fridge with no problems. And I'm quite sensitive to rancid oil. It makes a fabulous vinaigrette. Lovely on steamed vegetables too.

          1. I use it for part of the oil in granola, breads and pastries, as well as vinaigrette. It's great on green beans and sweet potatoes and brushed over roasted pumpkin or winter squashes.
