No Boil Vitality Starter (Whoops)

[troglodytes]

I was brewing a Westy 12 clone last night and just realized this morning a grave error I made. I always do a vitality starter, and my exact process is to mash, sparge, transfer, boil. Draw off 1.5L of wort, cool down and let the yeast start going to town so that in about 4 hours they are active and starting to kruasen.

The problem is, last night I was preoccupied with the wort reduction for the quad and without thinking, drew off my 1.5L for my starter prior to it getting to boil. My guess is that the beer sat in the high 150s to low 160s temp range for about 15 minutes post sparge in the boil kettle, but with this beer being one that ages for a year plus I'm super worried about what I've done, and all of the potential bugs that could have just made its way in.

Do I have hope that the temp was high enough to pasteurize? Also, does the fact that I pitched 1.5L of 1.054 wort onto about 300B cells give me hope that the yeast in that huge of a concentration crowded any potential bugs out?

Low 160's is supposedly enough for flash pasteurization. IMO the issue is getting enough of your equipment to that temperature, I.E. The edge of the kettle the stirring ladle, brew bag etc. I routinely do no boil I like to go to the 165-170 range, though 75% of my beer gets consumed within two weeks. I have been boiling my starters though.

I've done many vitality starters and never boiled. I think after the mash at pretty high temps for an hour and with yeast going right into the starter you should be ok. though i've never kept beer for months.
