This is a guide of how to brew using a simple set up and methods. The methods followed are done for 3 main reasons.

  • It makes very good beer.
  • It allows for a short brew session
  • It keeps the equipment simple and therefore relativity cheap.

There maybe quicker, cheaper, simpler ways to brew but this is the way I do it. There are detailed articles on the reasons certain steps of a brew are done so this article will not explain why things are done but just how they are done. I know this method works and my water is suitable for brewing and gives good results.
In the interest of the KISS method. (Keep It Simple Stupid) I don't do the calculations for every brew unless I am doing a really high gravity brew. I don't test for starch conversion or treat my water. I also do not test for the gravity of my runnings because I know from experience that for a beer of around 5% to 6% my sparge runnings do not fall below 6%. For your first one or two brews you may wish to do some of these things.

Equipment used

  • HLT: A plastic pail with a domestic immersion heater
  • MLT: A converted cooler with a copper manifold and ball valve spigot
  • Kettle: A converted keg
  • Heat source : A 30,000 BTU propane burner.

Recipe

Hobgoblin Clone

Batch Size 23L
Pre Boil Volume 30L
Mash 68°C For 60 Mins
OG 1056
ABV 5.6%

4.80 kg Maris Otter Pale (2 Row) UK
0.25 kg Caramel/Crystal Malt - 60L
0.20 kg Cara-Pils/Dextrine
0.15 kg Chocolate Malt
45.00 gm Styrian Goldings
45.00 gm Fuggles
Danstar Nottingham Dry Yeast (1 pack)

Method

Preparations

Pre Boil a kettle of water and leave to cool. (For yeast hydration)

Water Volumes

Grain Bill: 5.4KG
Mash Ratio: 2.6L/KG
Mash Water: 14L (First runnings 6L)
Sparge Water: 24L

Set up the brewing equipment

Set up you HLT, MLT and Kettle. This equipment needs to be clean but not sanitised

Heat the sparge water

heat 14L of water to 77°C this take me around 30 minutes and gives time to prepare my grain and hops.

Weigh the ingredients

If you weigh and lay out all you ingredients then it's less likely that you will forget a step in the brewing process.

Mashing

Mashing at 68°C for 60 minutes will give the correct temperature and time for the enzymes in the malt to convert the starch to sugar.

  • Make sure the manifold is secured correctly
  • Make sure the tap is closed
  • Make sure the mash water is at the correct temp
  • Add the grain to the mash tun
  • Add the water to the mash tun and stir to make sure all the grain is wetted, don't forget the corners
  • Check the temperature to make sure it is 68°C
  • Close the lid and leave for 60 minutes

The time the mash takes can be used to mix a container of sanitiser and rehydrate the yeast

Rehydrate the yeast

Sanitise a glass, add the preboiled water, sprinkle on the yeast, cover with plastic wrap and leave in a warm place until required)

Heat your Sparge water

Heat 24L of water to 77°C Start to heat your sparge water around 30 minutes before the end of the mash.

First runnings

Use a jug to drain off some wort from the mash, return the first few jugfuls back to the mash until the runnings start to come out clearer. Drain all the first runnings into a pail and add to the kettle. In the interest of speeding up your brew day, you may wish to start heating the kettle at this point. If you do then be careful not to heat to vigorously or you'll caramelise the wort

Batch sparging

Depending on the size of you mash tun you will need to add your sparge water in one, two or even three parts. Add the water and stir to mix. leave for 5 to ten minutes, mix again then drain, returning the first few jugfuls to the mash until running clearer. Add to the kettle and repeat.

For your first one or two brews to may want to check that the runnings do not drop to a gravity of less the 1006. This can cause the extraction of tannins from the grain and cause and harsh/astringent off flavour. If the gravity does drop 2 low then stop sparging. You can top the kettle up to the required volume with water or just live with th3 smaller volume.

Boiling

Boiling is done for several reasons.

  • To reduce the volume of the wort and concentrate it's sugar contents
  • To allow for the addition of bittering and flavouring hops
  • To drive of unwanted volatile compounds
  • To sanitise the wort.
  • To cause proteins to coagulate and improve clarity
