Canning starters
Posted: Sat Aug 08, 2009 10:30 pm
I pressure canned 29 quarts and 6 half gallon yeast starters
. The process was basically just like making an all grain beer to have a preboil gravity of about 1.040. For me that was 14 lbs of US 2 row for 10 gallons. Once the wort was made I filled the canning type quart and half gallon jars till about 1 inch from the top, and placed 2-4 inches of water in the canner (after jars are in the pot). Heated the canner till steaming for a few minutes before putting on the weight (or jiggler). Let the canner climb in pressure till 15 lbs and maintained that for 15 min before turning off the heat. Allow the canner to cool and depressurize naturally. The jars and contents are still very hot at this time so be careful when removing the jars to start the canning process over again.
Sure took a long time canning 7 qts each time, but doing the math of how much time and money it takes to make a starter using DME it was worth it.
Here's the math: Using a very rough estimate of time and excluding energy costs since everyone can use whatever heat source they normally use for cooking.
Normal DME method:
Gather ingredients and equipment: 5 min
weigh out DME: 2 min
Reach boil and boil 15 min: 20 min
Cool in ice water bath: 20 min
Cleanup (if not done while wort is cooling) 13 min
Total for half gallon: 1 hr and cost of DME $1.88 (using 8 oz @ $3.75/lb)
Canning method:
wort production:
14 lbs US 2 row for 10 gallons:
Gather equipment and weigh grain: 10 min
Heat strike water: 20 min
Mash in: 5 min
Mash: 90 min
Mash out: 20 min
Sparge: 1 hr
Clean up 15 min
Total for this process: 220 min and $9.24 for the grain
Canning production:
Fill Jars: 15 min
Heat pressure canner to steaming: 15 min
Pressure maintained at 15 lbs: 15 min
Cool canner to open: 30 min
Total: (60 min each batch)*6 batches + 15 min at end for clean up=375 min
Adding the wort production time (220 min) + canning time (375 min) = 595 min (about 10 hrs). This makes 20, half gallon starters. So about 30 minutes for each starter. Cost: $0.47 each starter ($9.24 for the grain/20 starters).
