Now I am curious how much money I could save with starsan:
Price Comparison of Dry Heat (oven) vs. Starsan
Gas prices in LA
are 49.786 cents/therm (1 Therm = aprox. 100,000 BTU)
An average roasting oven uses 30,000 BTU/hr
3 hours of operation for 48 bottles
$0.49786/100,000*(3*30,000) = $0.448 cents per bottling session
$9.99 for 8 oz bottle
1 oz to 5 gal --> $1.24 for gallons sanitizer
Assumption: 12 oz of Starsan dilution in a Vinator is consumed/discarded while sanitizing 48 bottles.
$1.24 / (5 gal * 128 oz/gal) *12 oz = $0.023 per bottling session
WOW, please tell me the math is broken somewhere. Head-to-head Star San wins in an epic fashion.
Just for kicks let's account for equipment costs (I know we should never count equipment cost), a bottling tree and vinator
costs $46.98, at savings of $0.42 for santizing enough bottles for a 5 gal batch, it would take 111 5-gal batches to recoup the upfront equipment cost. That is assuming that you lose 12 oz of the Star San dilution with each bottling session.
I'm cheating a little bit and not counting the cost of the oven for the Dry-Heat numbers, but hey who buys their oven for the express purpose of sterilizing bottles?
That was fun, now my number crunching OCD has been placated.
