Hi,

Because my batch of cider didn't turn out as strong as it should due to a
measuring hiccup (it's still tastes ok though) I thought I would do an
experiment. To save me heaps of time, I thought I would put my 750ml glass
home brew bottles in my dish washer and put it on an intensive (70 degree)
program. I also let it finish the cycle with the normal drying process.

I have gone ahead and bottled the cider in these bottles which looked
sparkling when they came out of the dish washer. I didn't sterilise the
bottles, I only sterilised the caps.

Would such a dish washing cycle be enough to sterilise the bottles? If this
works, it'll save me several hours. It took me about 30 minutes to bottle 25
750ml today, instead of the usual 3 to 3.5 hours (when I'd be cleaning and
sterilising each one by hand).

I rinse the freshly drunk bottles with hot water, and store upside down in
dish washer rack.  When I'm ready to bottle, I run them through the
dishwasher (no soap/detergent) with the heated drying turned on.  The heat
from drying zaps most nasties.  I have been doing this for 5+ years with no
problems.  Since I started with mini kegs (thanks Dan L.)  I only need a
dozen or so bottles per batch so I soak the bottles in bleach water
overnight and rinse with bottle washer until I can no longer smell the
bleach.  YMMV.

The problem with relying on a dishwasher to clean/sanitize your
bottles is two-fold:

1.  The design of beer bottles, with the narrow neck flaring out into
the main body, prevent a good stream of water from making it to all
parts of the bottle.  Thus, many portions of the bottle receive no
benefit and remain uncleaned by the hot water.

2.  The heated drying cycle of the dishwasher does not provide near
enough heat to properly sanitize the bottles either.

Using a 5 gallon bucket of Iodophor, I can sanitize 2 cases of 12 oz
bottles in less than an hour.  This includes time for them to drip
dry.  That's about how long a dishwasher cycle, with a heated dry,
takes, and I KNOW that every portion of the bottle was coated with a
proper sanitizer.

Sanitize, possibly.  (70 degrees C?  Probably good enough to kill most
wild yeast.)  Sterilize?  No, for that you'd need about 315 C, which
would probably crack the bottles.  (I'm assuming you mean sterilized
of all bacteria that could affect human beings.  Sterilized of all
life?  Probably in the neighborhood of 1100 C.  Remember, there's life
at the 300 C sea vents.)

And a dishwasher most likely won't get water up into all the bottles,
or into all of a bottle it gets some water into.

Clean and sanitize the bottles in a batch - soak them in cleaner (or
rinse each one right after emptying it), then in sanitizer, then rinse
one at a time.  25 bottles should take about 10 minutes to rinse, less
if you have a jet washer.  If you do, picking the bottles up and
setting them down takes most of the time.  The rinse is about 1
second.

Re: using a dish washer to clean & sterilise bottles


I have just recently bought bottles and found that sanitizing them took
forever!

Originally I was using a bleach so rinsing them out involved filling with
cold water and giving a good shake then repeating. This I found seemed to be
enough to get rid of the bleach smell.

I have since bought a sanitizing powder from my brew shop but have yet to
use this. Would this need less of a rinse?

Also, I do have a couple of 'grolch' style bottles. Is it okay to sanitize
these and then use them at a later date? I presume that they would stay
sanitized since nothing extra can get into the bottle...

Thanks,
Simon

The sanitizing powders sold for home brewing are much easier to rinse
(some advertise "no rinse") than bleach.

If you haven't gotten one of the faucet mounted jet washers,
definitely get that.  It is a brass U shaped tube that has a garden
hose thread.  It may require an adapter from the hardware store to
mount on a kitchen faucet.  Mine cost ~$5.  It saves lots of time.
Rinsing is just a matter of pressing the upside down bottle onto the
rinse tube and water shoots into the bottle and drains right out.  

The adapter stays mounted to the faucet and the regular aerator screws
into it when I'm not using the jet washer.  That little adapter has
proven handy for filling the aquarium, and my bottle washing bucket
with a length of garden hose.

Takes a second or two to rinse a bottle.  Especially good for rinsing
the yeast out of just poured bottles of home brew.

I don't know that I'd trust a grolch style bottle to remain clean.  In
theory it should work.  There's a good chance of a few droplets of
water being left behind (or condensing in the bottle) and if there's
any bacteria or mold, that and some traces of old yeast may be all
they need.  Water may stay between the cap and gasket and allow mold
to flourish there as well.

If the bottle was perfectly dry, I don't see why it wouldn't work.
(the caps look like they would seal with pressure or vacuum)

Re: using a dish washer to clean & sterilise bottles


do not use regular bleach in a dishwasher
it dissolves the rubber components of the system
somehow coca cola and pepsi do the same thing.
here is a helpful hint.
if your windshield wipers are old and squeak, then pour a used cola on the
windshield in a good rain.
good rain duz not mean drizzle.
it will dissolve the rubber
AND people drink this stuff?

the only addituive to use in a dishwasher is washing soda.
never more than 30 percent.

a superior clean when you need the bottles to be clean

It depends on YOUR dishwasher.  If it's got a sanitize cycle, it's
probably OK.  If not, I wouldn't trust it.  I've seen studies where a
palte is innoculated from a dishwasher "sanitized" bottle and there was
definitely cuture growth indicationg that the bottle had not been
sanitized.  It depends on how much risk you want to take to save a
minimal amount of effort.

wow
if you were in canada, you could run as a politician.
say little, speak lots.
reminds me of the guy who hooked up his dishwasher to the cold water pipe
and was pissed off it took 15 hours for the sani cycle to work.

and life does not begin at 40 when ya went like 60 at 20.
but ya is close.

Forget the dishwasher, notice it's called a dishwasher!  Not a
dishwasher and home brew bottle sanitizer.   Forget "sterilize" think
"sanitize".   Les says " rinse the freshly drunk bottles..." this is
 the key to success".  I use the dishwasher, I rinse the bottlles
immediately after use, and set aside; before refilling I soak 2 min or
more in iodophor, give a quick rinse (just 'cause), then stick the
bottles upside down on the dishwasher spikes to dry.  I have found two
bad bottles in the last two years, because I've failed to follow my
own advice.  Some where between "rinse after use" and "refilling",l
eyeball the bottles and make sure there is no debris in the bottom!!!

Good luck and worry not,

Re: using a dish washer to clean & sterilise bottles


i like you
clean the bottle immediate, since the brewers yeast sets like concrete.
bottom rack is best for cleaning
then ya wash it again before you use it again.
simplicity.
you can pull up your pants anytime.
ignore the dry cycle
a waste of time

my personal routine is to store the bottles in the oven.
until my batch is ready to go.

Re: using a dish washer to clean & sterilise bottles


I have a newer dishwasher with a sanitize cycle, and the salesman wondered
why I was similing at the "sanitize the baby bottles" line he was feeding
us.  I've run all my bottles through it for the last 3 years and have not
had a single problem.  Even though I take the lazy way, I use Cascade or
whatever in the 1st cup, and use 1-Step or similar in the 2nd stage.
I've even put the brew-ware tools in there, and have removed the top rack
for buckets, etc.
