Beer Kit Instructions – How to brew beer from a kit

Two can or all malt beer kits are the pinnacle of beer kit brewing, these kits are available in a wide range of beer styles and are the best that can be experienced in home brewing before taking up extract or grain brewing.

This kit is Bardon bitter from Matchless Homebrew.

Brewing beer from a kit

The kit contains two cans of hopped malt extract, comprehensive instructions and a sachet of yeast.

Brewing Beer kits

Recommended equipment is two 30l fermentation buckets with lids and taps, your choice of sanitising solution, a kettle, thermometer, hydrometer and trial jar and campden tablets or campden powder.
The first stage of the process is to clean and sanitise the fermentation buckets.
My recommendation before doing anything further is to dechlorinate your brewing water. Using 1/2 a crushed campden tablet or the equivalent of campden powder stirred into 25L of tap water will immediately remove all chlorine and chloramines which can give your finished beer a chemical or medicine taste.
Adding the campden powder to the tap water

Adding Campden to brewing water

Take the water required to be heated from the treated water and boil it in your kettle.

Making beer from a kit

Standing the two cans in hot water for 5 minutes prior to opening will soften the contents and make them easier to work with. Make sure to use a clean can opener.

Cans of hopped malt extract

Empty the can contents into the fermenting vessel.

Pouring malt extract

Use some of the boiled treated water to rinse out all of the can contents.

Get the malt extract out of the can

Empty the dissolved contents of the cans into the fermenting vessel.
Warning the can will be very hot, use oven gloves or similar to protect your hands!
Stir to dissolve the bulk of the malt extract in the hot water added from the can.

Stir to disolve the Malt Extract

Using the tap on the bucket containing your treated water, drop your treated water into the dissolved kit contents. This will ensure thorough mixing and also aerate your wort to give the yeast the best possible start.

brewing with a beer kit

Check that the temperature of your wort is between 20 and 28 Celsius.

The right temperature for fermentation

If the temperature is correct add the yeast.

Adding yeast to a beer kit

Take a gravity reading. In this case 1.040. If you plan to return the sample to the fermenter make sure that the hydrometer and trial jar were sanitised.

28 hours in and the yeast head looks like this.

7 days later and fermentation is finished
This is how it looks after a week, after another 3 days, it’ll clear down considerably and be ready for kegging.

Fermentation complete

OK so it’s been 8 days, gravity is 1.012, but now it’s time to keg.
I will be using a plastic home brew keg for this how to.
The keg was cleaned with Oxyclean, then sanitised with a solution of cheap, thin, unscented bleach. Then rinsed well with cold tap water and finally swilled out with a kettle of boiling water. (Be careful)
50g of sugar (I used demerera, but use what you prefer) was weighed out.

Sugar for carbonating beer

The sugar was added to the keg.
Using a length of hose from the tap on the fermenter, the beer was run into the keg which mixed in the sugar.

Racking beer to keg

Once all the beer was in the keg a burst of gas from an S30 cylinder was added.

After 5 minutes to allow the CO2 to settle, the lid was cracked to vent the air in the keg and leave a protective blanket of CO2.
This keg has a mechanical pressure relief valve, a further squirt of gas and the indicator can be seen to be OK (Green showing)

This guide was written by The Homebrew Forum member, ‘Oblivious’. It’s a superbly simple ‘how to’ guide which tells you how to harvest yeast for brewing.
You can find the original thread here.

How to harvest yeast for brewing

This is my method of yeast harvesting, this was done for my last brew a Saison with WLP550

After racking the beer to the keg pour the remaining liquid, trub and yeast into a sterilized container. I find one around 2 liters to be a good size. Place the full container in the fridge for a few hours.

Harvesting yeast

The trub being heavier, will settle out faster than the live yeast. It is the liquid part we are interested in as this will have a greater concentration of viable yeast. Pour this liquid off into a new sterilized container, this can be of a smaller than the first and place in the fridge over night.

Reusing yeast

As the liquid we placed in the container is yeast rich, we want to harvest the sediment in this container. Decant of the majority of the liquid and transfer the rest includin the sediment to your storage vessel, I use sterilized 50ml tubes.

Yeast Sediment

Yeast harvesting

Decant off the majority of the liquid and pour the yeast in to your selected container. I find there is enough yeast  in each of these tubes to pitch into a starter for a month or so. Over that it I would add two of the tubes to a starter.

Yeast Vials

The answer is a lot simpler than you might think: Use a sanitised metal ruler!

Before you brew, fill your boil kettle up in small increments. Each time you add another litre of water (or whatever your unit of measurement is) – dip the ruler into the boil kettle and take a reading of the measurement. Then when you need to know how much liquid is in your kettle during brewing, simply dip the ruler in and check what volume was recorded at that measurement!

You could also do the same thing but using a wooden spoon – score a line for each litre and a thicker line for every 5 litres to make it easy to read.

An airlock is a water-barrier that allows co2 to escape during fermentation, without allowing airborne particles, bacteria or insects to enter the fermentation vessel.

A U-bend Style Airlock

A blow-off tube replaces the airlock in a fermentation vessel. One end attaches to the top of the fermentation vessel and the other end is submersed in a container full of water.

A Blow-off Tube

Which one should I use?

For most brews, an airlock is fine. The advantage of an airlock is that it is relatively small compared to the blow-off tube, and is much easier to maintain. The problem with airlocks is that a very aggressive fermentation can clog the airlock with Krausen, causing a build up of pressure in the fermentation vessel. When that pressure gets too much, either the airlock or the lid of the fermentation vessel will pop off with great force, causing a big mess. A blow-off tube is much less likely to clog up than an airlock.

A Clogged Airlock

If you are brewing a beer using a top-fermenting yeast (most wheat-beers are brewed using this type of yeast), then you should always use a blow-off tube. This is because top-fermenting yeast produce a much higher, thicker krausen than regular ale yeasts and are much more likely to cause problems when using an airlock.

How to make a blow-off tube.

1. Attach a piece of sanitised tubing to the opening of your demijohn (or lid of your fermentation bucket) using a sanitised stopper with a hole in it.
2. Half-fill a small container such as a measuring jug or pint glass with water, and place the other end of the tube inside, below the level of the water. You do NOT need to use bleach or sanitising solution for this!
