What yeast came with your kit? It may have been a Champagne type yeast anyway. What was the starting SG of kit? Should be no reason since you are not adding k-meta plus sorbate that there would not be live yeast available. They will continue to reproduce as long as they have sugar UNLESS they die off due to ETOH toxicity.
You could try some with #1 and #2 if you were curious about best result for you.
