Ok, my first Brew Day (see here) is worrying me a bit now regarding the yeast. It has really ‘taken off’ and I am unsure what to do, if anything. The yeast has climbed all the way to the top of the FV and up through the airlock – it actually blew the top off.
Here is a picture of it this morning:

Should I remove the top of the FV, scrape off some of the yeast, clean and sanitise the top + airlock, and then replace top, or something else?
Bit worried

Thanks in advance
Mark.
