+ 1 ON THAT
Every time you take that lid off you are giving the bugs a chance to get in!!!!!!!!!!!!!!!!!
Brewing is simple, no need to keep playing with it. I understand you are keen & interested but you need to relax & let it do it's thing.
At this stage of your brewing addiction you should be doing just 4 simple steps.
Sanitise.
Mix your ingredients & cover.
Wait two weeks.
Bottle.
You may get the odd dodgy one (which I don't think you have) when you first start out if your sanitation is not up to scratch but if you keep opening it up you will get MANY dodgy ones.
Remember, bacteria are all around us, in the air we breathe & almost every thing we touch. Even the air we breathe out will be laden with more bacteria than when it was breathed in. There will be a layer of Co2 sitting on top of your beer which helps protect it but it is by no means a barrier if disturbed.
You need to keep that space inside the fermenter totally isolated from the outside atmosphere.
Some of us use ClingWrap & a big rubber band in place of a lid so we can see in without taking a lid off.
