Individually priming each bottle before
filling is a time consuming, messy and potentially inaccurate
method of conditioning (carbonating) your beer.
This is how to go about bulk priming
using your R&B bin (racking & bottling bin)
1 EXTRA FERMENTER- (R&B bin) the same
size as your primary fermenter.
1 LENGTH OF TUBING- about 2m in length.
1 TUBE TO TAP ADAPTOR.
1 EXTRA TAP- for your R&B bin.
It goes without saying that the first
step is to thoroughly sterilize all the equipment.
Next, place your fermenter (the one with
your brew in it) on the bench and position your R&B bin on the
floor below it. Fit the length of tubing onto the tap of your
fermenter with the brew in it, using the adaptor if necessary,
then run the other end of the tubing through the grommet hole in
the R&B bin lid pushing the tubing right to the bottom of the
bin, keep going until the tubing is curled at least a half
circle, this will ensure the brew is moved gently into the
bottom of the bottling bin helping to eliminate the introduction
of oxygen to the brew, it also mixes the priming solution.
The priming solution is simply 220g
to 230g Dextrose dissolved in 400ml of boiling water,
have this prepared in a covered container.
OK, you’ve got your R&B bin in position
and ready to go, tip the priming solution into it and put the
lid back on, next release the seal on the fermented containing
With screw top fermenters simply
unscrew the lid and leave in position, with clip lid types just
unclip one section, doing this will stop the liquid in your
airlock being sucked back into the brew, alternatively, pull the
airlock out of the lid.
Turn on the tap, get yourself a glass of
HomeBrew, essential for the next step, bottling.
As soon as the tap starts to suck air,
either turn it off or tilt the fermented to pick up the last
litre or so. Now gently stir the brew, about 6 revolutions is
It is now time to bottle – of course you
have your already sterilized bottles waiting to be filled. Lift
the now filled R&B bin onto your work bench, leaving the tubing
attached if you can, now change the tubing from the fermented
tap to the R&B bin tap, withdraw the tube from the R&B bin and
attach your brewers bottler to it. You can fill your bottles by
lining them up on the floor and going from bottle to bottle with
the flexible tube. Better still arrange things so your R&B bin
is up above your bench work surface then you can bottle your
beer in comfort at about waist height.
The reason I started bulk priming was
the same reason the Yanks do, I wanted to bottle my brews into
stubbies (in the US they don’t have 750’s) and priming 60
bottles is bad enough but I usually do a couple of batches at a
time hence my interest. What I didn’t anticipate was the
improvement in the condition of the beer. It seems that the use
of dextrose, which we already knew was a faster and cleaner
fermentable, greatly enhances the beading of the beer. That is
it quickly produces a finished beer with very fine bubbles, this
presents as a fine creamy head which provides excellent lace on
the glass – just what the home brewer ordered!
