Guidelines for steeping specialty grain.
100 gms roast malt in a stout or dark ale, can be called black or patent malt
150 grams of chocolate malt in a dark ale or stout
200 gms of crystal malt in any pale ale, dark ale or stout
150 gms carapils in a lager
This is for a standard brew of volume 23 litres and you will also need your standard kit and kilo of additives. All grains should be cracked, steeped in a litre of warm (40-60 degC) water for 30 minutes, strained, NO SQUEEZING THE GRAIN, grains thrown away, remaining wort simmered for 15 minutes and added to the fermenter with the rest of you kit and kilo.
Do not exceed these quantities of grain. If you brew this and like it, then, increase by 50%. This is definitely an area where too much will spoil a good thing.
While simmering, you can also add extra hops. Add some extra DME and a litre or two of water, 15 gms of your favourite hop and simmer for 10 minutes.
Add another 15 gms of hop and simmer for 10 minutes.
Add another 15 gms of hops, simmer for 2 minutes, cover with lid, turn off, chill in sink by standing in a few litres cold water, change the water to chill the saucepan, strain contents to fermenter and add your kit and kilo.
Do not use high alpha hops such as Pride of Ringwood, super alpha or cluster. Boiling 15 gms of high alpha hops for 20 minutes will impart too much bitterness. Use hops such as Fuggles or goldings in ales and hallertau, tettnang or saaz in lagers. If you wish to use POR, delete the first hop addition that is boiled for 20 minutes.
Adding some specialty grain and hops will really improve all kits.
Do not use base grains such as pale ale, schooner, sloop, smoked, amber malt, Munich, Vienna, wheat, lager or pilsner. These need mashing at 65 deg C rather than just steeping at 40-60 degrees. If you try and steep these grains, you will only get starch which will not help your brew.
Do not boil grains unless you are doing a decoction which is advanced mashing. Boiling extracts tannins which is nasty. Steep the specialty grains, strain and then boil the resulting solution.
