When's a Cyser not a Cyser

If I made Apfelwien and a Show Mead... and blended them before bottling. Would that be considered a Cyser?

If I made a White wine, and blended it with a show mead would that not be a Pyment?


Does a pyment and a cyser have to be defined before fermentation?

Are there rules, and who made them?

Rules, no not really and the BATF won't come knocking if you mix your brews. But like beer or other wines there are style guidlines like those from the BJCP for meads and braggots. The Mazer Cup follows the BJCP guidlines for submissions. If you are just brewing for yourself and your friends do you really care? And why do all the mixing? Wouldn't it be more prudent to just brew a pyment or cyser and not risk the aeration or off flavors?
