bubbles between MT and boiler

[matthewdick23]

So I finally was able to add tubes to my MT and hlt.  Did a brew on Sat- and when I was moving the wort from mash to boiler, there was a lot of bubbles in the tube.

From what I understand, hot side aeration is debated.  I've attached a pic, but its not the clearest in the world

brewday went fine. no off flavours in beer at any stage.  the bubbles were very small

any thoughts?

thanks

I'd say your beer is screwed. When it ferments out get it into bottles and gimme a call. Ill come round and dispose of it for you:)

the valve between mash and boiler isn't airtight and air is being drawn in with your flow.
I deliberately unscrew slightly the barb after the tap on my boiler as I flush into fermenter and get loads of air bubbles, "every little helps"!

Thats looks like it was some party

Did you say the bubbles were from Mash tun to Boiler?
Is that a problem?

yes, it's between mash tun and boiler- as I'm sparging

ciderhead- ur saying u introduce air in at that stage on purpose, so Im not to worry?

[johnrm]

Air at this stage is fine.
After fermentation is when you don't want any more air.

You have to aerate wort after pitching yeast anyway so few bubbles on that stage shouldn't do any harm.

before or after?

He was trasferring from Mash to boiler so bubbles are not good.

I've read and listened to  prof Charlie Bamford talking about hot side aeration. It seems it really is nothing to be worried about at the hb level. Just no getting into the boiler and doing a dance.

Good to know, I never gave this much thought.
What is the effect at this stage?
Surely and oxygen picked up is going to be boiled out.

Re:bubbles in the tubing - I had this issue when bottling with a little bottler.
What I used to do was add the bottler pointing down (Ready for filling) but on starting bottling there would always be a small amount of bubbles in the tube.

Solution...
Purge your tubing of air:
Add bottle filling stick POINTING UP.
Open Spigot/Tap
Place the first empty bottle on the stick as if filling, filler stick will start to fill.
Keeping pressure on, rotate the bottle and stick to filling position.
Filling should now be bubble free.

The same thinking should apply to Mash > Boiler transfer.
