Terry,

Keep it simple mate.
Off flavours must be eliminated & you need to follow the simple steps
correctly to make life bearable & produce sound brews:
Practice good sanitation on all items used. Use iodine based sanitisers,
peroxide,  bleach, or sodium metabisulphite as your bug killing agents. I
recommend household bleach 50:50 with hot water. You need to finally rinse
clean in hot water &/or cold FILTERED water.
"Metabisulphite" is a sanitising solution made up & favoured by many
brewers. Available at any brew shop & requires less careful rinsing.
Your fermenter must be as sanitary as you can make it, & should be covered
every moment until you finally seal for primary fermentation. Always use a
bubble trap lock with salty water or metabisulphite solution as the fluid
seal.
Your bottles & caps must be sanitary also but need not receive meticulous
attention, suggest an initial bleach treatment, store dry protected from
insect & dust intrusion.
Get the yeast culture started in the wort within 4 to 8 hours, should be
vigorous at 8 hours. To do this I always use two different but "same style"
yeasts.  Pitch at controlled temperature (use refrigerated water or hot
water to adjust) in range 22-24 degrees, I pitch directly onto the wort
foam, I do not favour the starter technique.
Use a reliable (& sterile) thermometer & not the stick on strip indicaters.
This will pretty much guarantee an infection free fermentation & the rest is
relatively easy.
Hope this helps & probably confirms what you alredy knew.

Household bleach can be a two edged sword.  Although it will work, it
requires, as you noted, LOTS of rinsing.  Also, it is just to easy to
buy the scented stuff which is bad.

A 50:50 mix is WAY WAY WAY too much bleach.  We used to put just a few
capfuls of bleach into a military water buffalo (holding several
hundred gallons) to reach the appropriate amount to sanitize the
inside of the thing.

Agreed about keeping the fermenter as sanitary as possible, but you
seem to go a little overboard.  I've never used anything except plain
old water in my airlock with no problems or infections to date.

Just tone down the amount of your bleach mix and I agree.

Depending on the type of yeast you are using, a starter may or may not
be necessary.  I've never used two different kinds, nor have I ever
had fermentation producing bubbles at only 8 hours.  Yeast need some
lag time to use the dissolved oxygen in the wort to reproduce before
they start fermenting the sugars - and that takes several hours.

Re: protection against bacteria


sodium metabisulphide, ammonia and bleach and iodine are actually all
poisons.
i got off that years ago.
my failure rate is usually 1 in 20 batches.

i chalk that up to maybe the helper crew was not washing their hands
properly.
But they enjoy being put into a slavery work gang.
and what the hell, they make drudgery and tedium into a bit of fun.
(don't tell them that.)

Re: protection against bacteria


I've never had a problem using plain tap water to rise & for wort. As long
as the bottle is clean after you rinse, you will be fine. In my experience,
I have not needed to sanitize and I get good beer naturally.

Re: protection against bacteria


i like pete
loads of good info out of him.

only comment is personal sanitary situations while you make beer.
sanitize this
sterilize that.
so you washed your last tuesday, and make beer, and went to the bathroom
five times, and shoved your finger up your n ose 4 times.
the weakest link. the easiest way of infection is not boiling the hell out
of anything, but just simple sanitary rules.
hand cleaners are, things like, scented oranges, maybe fruit essence.
Perhaps, it is skin moisturizing, delicate.
You wash your hands but you still have fingernails fuill of black grease and
grine.
but you want to be clean?
Sing the happy birthday song 3 times while you wash your hands, and use a
nail scrubber if you need it.
actually when some opf my helpers show up on beer day.
i just send them down to the sauna and the pool with a good quality cleaner.
wow they almost look human.
