# What do we need
|
|
|
|
I'll outline how my brewing process unfolds over time to help list out all the things we need in the basement.
|
|
All amounts are based on a **20l to 25l** end product.
|
|
|
|
## Brew day
|
|
|
|
My brew day takes about **3 to 4 hours** from start to finish.
|
|
Doing 10l or 20l is pretty much the same time.
|
|
I haven't done any brews much bigger than that but I suspect anything up to 30l is doable in the same amount of time with a similar system as the one I'm describing.
|
|
|
|
### Preparation
|
|
|
|
I start my brewing session by milling grains, about 5kg for a 20l batch.
|
|
For this you need two things.
|
|
|
|
1. a kitchen scale to weigh the grains
|
|
1. a mill with adjustable spacing
|
|
1. a container of some sorts to weigh the grains in
|
|
1. a container of some sorts to catch the milled grains in
|
|
|
|
I use my Kenwood kitchen aid to mill and a 10l food grade bucket to collect the milled grains.
|
|
This takes about 10min.
|
|
|
|
### Mashing
|
|
|
|
I used to mash on my stove top, but recently switched to a bucket system.
|
|
For the stove top brew I did a BIAB (brew in a bag) system which is basically a huge tea bag you dump into the pot.
|
|
Anyway, the point of mashing is to steep the grains for **60min** at about **64°C** in about **20l** of water.
|
|
I use a 2000watt submersion boiler I got off amazon which takes about 30min to go from 40°C to, what we call striking temperate, which is about 67°C.
|
|
My heating element is plugged into a temperature controller, also from amazon, and this keep the mash stable for the whole duration.
|
|
So, in short we'll need:
|
|
|
|
1. a source of fresh water
|
|
1. a mashtun (big vessel we can heat up to our desired temperature)
|
|
1. a heat source of some sorts (can be electric, gas, ...)
|
|
1. a big spoon to stir the mash from time to time so it doesn't get stuck
|
|
|
|
During this hour there is not much to do but wait and have a beer.
|
|
At about 15min from the end, I start heating up about 10l of **sparge** water to about 70°C.
|
|
This will be used in the next stage.
|
|
I often weigh my hops at this stage, so we'll also need:
|
|
|
|
1. a kitchen scale
|
|
1. a couple, two or three, small containers to put the weighed hops in
|
|
|
|
### From mashing to boiling
|
|
|
|
Once the 60min are up it is time to extract the wort from the mash.
|
|
Wort is basically the water without the spent grains.
|
|
For this we'll need a filter system.
|
|
With a BIAB system this is super easy, you just lift the grains out and let them leak into a **second** bucket.
|
|
We'll probably end up with a all-in-one system that has this built in though.
|
|
|
|
We'll now try to extract the most sugars as possible from the mash.
|
|
The spent grains will have absorbed a lot of water, probably about 5l so we'll need to make up for that.
|
|
This is what the **sparge** water is for.
|
|
It is poured over the spent grains and caught in the **second bucket**.
|
|
While this is happening, which takes some time, we can already bring the wort to a boil.
|
|
|
|
At this stage we'll need:
|
|
|
|
1. a bucket to collect the sparge water in
|
|
1. a heating source to go from 67°C to a rolling boil
|
|
1. a vessel to boil the wort in
|
|
|
|
The sparge water is added to the wort and brought to a boil all together.
|
|
Going from 67°C to 100°C takes about 30min on my 2000watt system.
|
|
|
|
### Boiling
|
|
|
|
Not a lot is happening here so it's time for an other beer.
|
|
We need to boil the wort for about 60min and add hops at specific times.
|
|
The amount of hops and timing is very variable but I tend to go for two additions.
|
|
One in the beginning for bitterness, and one at flameout (the end) for flavor.
|
|
At the minimum we'll need:
|
|
|
|
1. a couple of hop bags
|
|
|
|
I use this time to prepare the fermentation vessels.
|
|
This is basic sanitization.
|
|
For this we'll need some specialized products, the most famous one is called Starsan.
|
|
|
|
1. sanitization product
|
|
|
|
### Chilling
|
|
|
|
Once the boil is finished we want to cool the wort as quickly as possible.
|
|
We want the wort to go to about 30°C at the maximum, and colder is better, with 20°C as a minimum.
|
|
My current system is very ghetto, I cool by placing a bit metal pot in my sink with cold water that I refresh every 15min, but there are very nice systems on the market.
|
|
|
|
1. a chilling coil
|
|
1. a water pump
|
|
1. about 100l of cold water
|
|
|
|
### Transfer to fermentation
|
|
|
|
Once the wort is at room temperature we can go ahead and transfer it to a sanitized fermentation vessel.
|
|
Here we'll add the yeast, put on a water lock and clean up.
|
|
|
|
1. precision scale to weigh the yeast (about 10g for a 20l batch)
|
|
1. fermentation vessel
|
|
1. water lock
|
|
|
|
### Clean up
|
|
|
|
We'll have about 10kg of spent grains to get rid of, plus heaps of tools to clean.
|
|
I do everything by hand in my shower and kitchen so some sort of flexible wet room is advised.
|
|
|
|
1. basic cleaning products
|
|
1. lot's of water and a way to get rid of it
|
|
|
|
## Fermentation
|
|
|
|
Nothing to do here but wait.
|
|
It takes about 2 weeks for the main fermentation to complete.
|
|
|
|
## Dry hopping
|
|
|
|
When making an IPA, you'll want to add fresh hops after about 2 weeks, and let them in for a small week.
|
|
For this we'll need an other hop bag and scale.
|
|
The bag should be sanitized.
|
|
|
|
1. a kitchen scale
|
|
1. hop bag
|
|
|
|
## Bottle day
|
|
|
|
For a 20l batch you'll need about 70 bottles cleaned, sanitized and ready to go.
|
|
Make no mistake, cleaning takes a lot of time.
|
|
To clean a big batch of bottles I need about an hour and a half by myself.
|
|
The tools are easy though.
|
|
|
|
1. steady flow of water
|
|
1. bottles to clean
|
|
1. sanitizing product
|
|
|
|
To actually *bottle* we'll first transfer the fermented liquid to a **second** vessel with a **tap** at the bottom that has been sanitized.
|
|
In this vessel we'll need about 7grams/liter of dissolved sugar (in water) for bottle carbonation.
|
|
I do this with a silicone tube and old school suction power.
|
|
|
|
1. silicone tube (about 2m max)
|
|
1. scale to weigh the sugar
|
|
1. kettle to boil some water
|
|
|
|
Once the fermented beer is in the secondary vessel we can bottle.
|
|
For this we need a bottling tool and a capping tool.
|
|
It's handy to have the bottling tool on some tubing so you're more flexible.
|
|
Anyway.
|
|
|
|
1. some tubing
|
|
1. a bottling tool
|
|
1. a capping device
|
|
|
|
## Final cleaning
|
|
|
|
There is not much to clean up on bottling day.
|
|
A *just* bottling day takes about two hours for a 25l batch with a very minimal cleanup.
