Using PET bottles and the wrong fresh yeast strain would likely produce gushers.An important consideration if using glass bottles IMO.
In either case, paying attention to the details will prevent badly packaged batches.
As for "inventory management", always have a couple of packages of CBC-1 or EC-1118 in the fridge/freeze. If CBC-1 is "too expensive", EC-1118 is available in 10 packs for around $6.90 (plus shipping).
