Sight Glass a Risk?

[Stevo2569]

This is an overheating situation, not uncommon but its burner dependent. Use a heat shield.

It happens on both my HLT(with heat shield) and BK(without but, flames don't hit it).

Did a batch this morning and put the thermometer down in the sight glass. 120 degrees measured at different points throughout the boil.

I posted a graph and further data here:

It's a bit of a surprise. I might have to consider a change to my process actually.

I appreciate your doing that. I'm planning on going electric. No site glass yet. I wondered if I was over thinking it but it appears not. I had thought sanitizer down the sight glass and then loosely capping it with aluminum foil. The reality is cleaning it is probably good most of the time but the one time it isn't is when you've made a big beer that ages for a year or more. Then little buggers have a chance to multiply and grow over time. Obviously you are at the mercy of what is in the air which may not matter 99.95% of the time.

In reality though... everything in the kettle has been at 150-160 for an hour to mash, then bumped up to 170 or so to mash out before it ever saw the sight glass, unless you are doing extract.

Then, unless you use an immersion chiller, it recombined with the 200+ degree worth before going through a chiller.?

I wouldn't worry about it.
