How does the cost of dry yeast compare to conventional yeast propagation?
The cost of propagation is often unknown to the brewer. The capital expenditure in a propagation plant only accounts for c. 20% of the overall cost of yeast propagation with the remaining 80% corresponding to utilities, labour & supervision, maintenance, QC and production materials (wort) costs. In most cases dry yeast compares favourably to propagated yeast and brings additional advantages (flexibility, pre-QC cleared product, etc.).
