Canned wort: concentrate vs non-concentrate; hot break material

[EscapeArtistBrewing]

Couple of canned wort questions. I am assuming employing proper pressure canning techniques, using non-chlorinated water, the whole proper operation list...

1. Is there a downside, other than using more jars, to canning a 1.035 SG solution of DME for direct pitching vs the more common 1.080 SG (or higher), which requires dilution? It seems easier just to add the wort directly vs having to prepare a diluent. Might wort concentration affect the canning effectiveness?

2. It seems I get as much hot break when canning a 1.035 solution as when canning a concentrate. Should one attempt to decant the hot break in a canned wort, or do the yeasties do just as well with the proteins and other material in the break material?

1. I can all my wort around 1.040. Wort concentration may have an effect on canning, but since there is no known officially confirmed process for pressure canning wort, we can't tell. It would seem to me that the density differences in normal wort would not have an effect on canning times. I build safety factors into my canning process so that I can feel confident that the wort is sterilized. I base the times off of the tested methods for canning meat broth with bits of meat, then add time and pressure on top of that. The recipe that came with my canner says 25 min at 10psi for quarts of beef or chicken stock. I do >30 min at 15psi for quarts of wort.
2. If there is a lot of hot break and it is easy to decant, I'll leave some in the jar when pouring into the starter, but I don't stress about it. If it all goes in, so be it.

Ditto for me on time/pressure, Marc. Skimping on processing parameters seems dubious at best. What I like best is I can measure in a stock pot and tune the SG exactly, then ladle into jars. No guessing or approximations (for some reason I can never seem to hit the SG exactly just doing calculations). Thanks for voting with me on non-concentrated.

(for no other reason than reassurance...)
