    My experience is yes, I've started new batches of Replenished Xtol with year old Xtol stock.

    Thanks Ian.
    I'm trying to understand if the developer by-products (bromides?) present in a replenished line has any effect at all for longevity.

    The more I think about it I would assume they wouldn't either stifle or promote oxidation but we all know what happens when we assume. Especially where chemicals are involved

    Bruce, because I was spending most of my time in Turkey and only visiting the UK twice a year (last 4-5 years) my Replenished Xtol would sit idle for months in storage. I ran test films through before using and found no differences after a year in storage I would previously have been turning over a 5 litre batch split 50:50 stock and repleniosher in under a year, more like 6 months often continuing replenishment with another pack of Xtol for up to 2 years before starting afresh.

    Seems it's fairly robust despite the stories on the internet and possible problems they had with it at one time.

    Thanks for sharing your experiences.

    I have gotten one year in the past (though I usually use it up well before then). I mix with distilled water and store in one of those accordion-style containers. Xtol can last a long time if properly stored.

    I first tried XTol almost 2 years ago and then preceded to use it for all my pushes. That lasted for about 1.5 years before it went flat, with about 1 ltr left. The last run I actually put a leader in the stuff and made sure it turned black. It did, but my roll still came out clear.

    I worked out of a 4l and a 1l bottle. I actively used the 1l bottle and refilled it from the 4l. They were just juice jugs, nothing special.

    Now I was using 1:2, which made it go a long way. However 1:2 gave me the look and texture I needed. For the price, who cares....

    Since then, I am trying the replenisher approach. It gives me the dev times of 1:2 ish, but sort of gives me the guarantee that the working solution should not go flat.

    Now my drum only uses 150 ml per 35/120 roll of film. When I used 1:2, I only threw out 50ml of xtol for a one-shot. Replenishing takes a 70ml top up. I guess I am using more with replenishing, but I think it is less likely I will loose a roll of film with it. Again, for the price, who cares.....

    It depends a lot of the quality of the (tap-) water. So in doubt use destilled water for Xtol and you will be fine for at least 6 months of a 5 ltr. stock. Dividing in smaller bottles will of course prolong the life time however over 9-10 months is not very wise with this type of Ascorbic Acid developer. You can also use the same type developer from Foma: Fomadon Excel W27 in the 1 ltr. packing. A tick more grain, for the rest (almost) the same.

    Using replenished XTOL and adding stock XTOL after each development, I have kept the replenished XTOL for over two years. Note that when I used up the stock XTOL, I mixed up fresh stock XTOL and continued. As long as the stock XTOL is less than a year old, I have had no problems.

    I mix my Xtol with distilled water and store it in many small (330 ml) glass bottles. I set some aside for an age test. After 3 years it was still fine. But remember I never have any air in the bottles. I open it and use it all at once.

    XTOL in a replenished line will last a long time - if it uses nitrogen burst agitation. The nitrogen bubbling through the developer will carry away oxygen as well as prevent air from getting at the developer.

    I had a batch of XTOL fail while clear a year ago. Probably 6 months old, stored in topped-up bottles. I had heard rumor that Kodak had somehow addressed the issue and so I bought a brand-new bag - same old stuff...
