First of all, freezing isn't the best option. Micro-nasties can still survive the freezing. This is especially bad if you are using these starters to re-culture from a yeast bank. It gives the micro-nasties a better chance at taking over. Also it takes up space in the freezer that could be better utilized (yeast bank
). Lastly, freezing just means you have to thaw, which doesn't really save any time/steps compared to making single starters.
If he's got the tools for PRESSURE canning, then canning is the best option. You literally take a jar off the shelf, pop it open, flame or spray the rim and you are done.
And with that, my jars of starter wort for the year or more
