the boil

[chris+spain]

somebody told me that when you are doing the boil you should never put the lid on to stop steam escaping.
is this true or just a beer myth?

ps just poured 25 L down the drain ( eggy !!!! ) very sad.

cheers lads

I usually put lid on till boil is achieved then remove lid so nasties can boil off it just speeds the boil up

As Eddie says, put the lid on till it reaches the boil, then remove once the boil gets going.

The boil removes DMS ( the cabbagy taste ) along with other nasties so leaving the lid on is a no no :nono:
If you want to reduce the evaporation cut a hole in the lid about 2/3rds of the size of the lid. Look for one of Tubby_shaw's post of his brewdays he uses a lid like the above.

 

I deliberately sparge to 5ltrs more than my final length.
This is to allow for the reduction during boiling (lid off).
