I'd be worried if there's an increased risk of mold growth.

You're worried mold is going to grow in the 5 minutes between grinding and brewing?

More like in the 24*60 - 5 minutes between brewing and grinding again the next day. In all seriousness: it can takes surprisingly little time for ground wet coffee to form mold. Think 48h range especially when it's relatively hot.

I've been doing this for years and haven't seen any evidence of mold, even in more humid summer months.
