Can someone tell me if DAP has an expiry period. Iâm using a DAP in my wine which I bought 1 year ago. I just donât think itâs bubbling like it should. Is the DAP maybe old?
I meant that I haven't noticed anyone else using it as an acronym. A Google search of the forum did find a few other instances, although users usually said âDAP nutrientâ.
It isn't in the forum glossary either, although Wikipedia does recognise it.
