All Grain Brewing Instructions
SUCCESSFUL BREWING
Due to the wide variety of brewing equipment, we have included generic instructions and should be used as basic guidelines.
You may find minor differences or a need to adjust times and amounts as you gain knowledge of your own system.
These recipes are based on a 75% efficiency. Efficiency can range from 65-80% depending on your system
MASH SCHEDULE (BOILING GRAIN TO MAKE WORT)
We
suggest you start with a single infusion mash schedule, which means you
infuse the malt with the strike water at a set temperature, usually for
60 minutes. On occasions, some recipes will call for step mashing which
means you step the temperatures up at different times to get the enzyme
activity from less highly modified malts. On occasion, a recipe with
adjuncts may call for a 90-minute mash to ensure conversion as opposed
to a 60-minute mash.
STRIKE WATER (WATER USED FOR MASHING)
We
suggest that you heat your strike water just slightly above the mash
temperature to allow for a small drop when adding the grains. If you're
using an all in one brewing system your mash temperature will be easily managed.
SPARGE WATER ((WATER USED FOR RINSING)
Sparging
is rinsing the grain used in the mash to get as much of the sugars out
as possible. Basically, you will separate the solids from the mash and
pour the sparge water through these solids to be collected into your
boiling vessel. The method used to do this will depend on your system.
The sparge water should be the same temperature as the strike water.
WATER AMOUNTS
The
amount of water you use can be calculated easily, check out our youtube
video “Brewery Mash & Sparge Water Calculations”. For mashing in we
suggest you use roughly 3 times the volume of water as to the Malt (e.g
5kg of grain = 15 litres of strike water). The absorption rate of the
grain is roughly 1litre per kilo leaving 10 litres so we need to sparge
to hit our pre-boil volume of 29.5 litres = 19 litres of sparge water.
BOIL ADDITIONS & TIMES
The boil will be for 60 minutes and your boiling time will only begin once your wort is at a rolling boil.
The
addition times start from when the boil begins, so if it states 60 min
addition, add that at the start of a 60-minute boil, if it states 10
mins you add that 10 mins before the end of the boil. We suggest that
you add the whirl floc tablet 10 mins before the end of the boil
You
will get a boil-off rate during the boil, which is about 4.5 litres in
an hour. So if you start with 29.5 litres, you should have 25 litres of
wort going into the fermenter.
AFTER THE BOIL
You want to cool the wort to your desired fermentation temperature as quickly as possible.
Make
sure you sanitise the fermentation equipment thoroughly and do not
forget to sanitise the yeast packet and the scissors used to cut the
pack open.
You should transfer the wort to the sanitised fermenter
and aerate the wort to get some oxygen into it. Then take a gravity
reading, also referred to as your SG (Starting Gravity). This is done
with a hydrometer to measure sugar content
Then cut open the yeast and sprinkle it onto the top of the wort
Place
your fermenter into your fermentation chamber and maintain a constant
temperature. Ensuring that the airlock is filled with water to protect
the wort whilst it ferments
PRIMARY FERMENTATION
Fermentation
progress can be observed visually with the activity in the airlock and
also by taking samples for gravity readings using your hydrometer. You
should also see a Krausen form on top of the wort, this shows
fermentation is active visually.
You will need to use the hydrometer
readings to monitor when you have hit the desired FG (Final Gravity),
and if it remains constant for 3 days then proceed to the next step.
DRY HOPPING
If
included, add dry hops after fermentation and following checking of
your gravity reading 1020 or below, the hops are added by placing the
hop tea bags into a cup of boiling water and allowing them to soak for a
few minutes then add the contents of the cup including the tea bags to
your fermenter. Ensure the lid with the airlock is sealed correctly. Hop
additions add a delicious aroma to your beer and are best added late in
fermentation, so allow them to soak in the fermenter for 2-3 days.
CRASH COOLING
At
this stage we suggest the wort is crashed cooled to drop out all the
sediment and hops, dropping the wort temperature below 4 degrees allows
this to take place.
SECONDARY FERMENTATION
This
step is optional, it means the beer can be transferred to another
fermentation vessel to condition for a period of time before proceeding
(usually 2 weeks). This time can be flexible for lager styles which can
take up to 6 weeks
BOTTLING OR KEGGING
There
is a lot of options available to you when it comes to packaging, you
can keg or bottle or indeed do a mixture of options. You also have
options to force carbonate with co2 or you can do bottle or keg
conditioning by adding priming sugar (dextrose monohydrate). If you are
priming you can do this in a batch or you can prime each bottle
individually. We suggest a level teaspoon per 500ml bottle is a good
guide for bottle priming, if using 5-litre mini-kegs we suggest 2-3g per
litre. You can use a bottling bucket and transfer the priming sugar and
beer into the bucket before starting to package, this leaves the
sediment behind in the primary fermenter and allows you to bottle with
ease. When bottling fill the bottles using a bottle filling stick and
cap as quickly as possible, avoid mixing and splashing. After the bottle
is primed with sugar and capped it needs to be kept somewhere warm for a
week to allow secondary fermentation to take place then we suggest
keeping it somewhere cold for 2 weeks to allow the beer to condition in
the bottle.
