Malted barley per gallon?

[Sttifyd35]

I want to a small test batch of beer. How much malted barley for 1 gallon?

Depends on the level of alcohol that you want to attain.

That is so dependent on what you are trying to achieve. A pale ale, an amber, a porter, a stout, a Belgian strong ale. All would use different amounts and different types of malted barley.

It is not how much per gallon, it is how much per gallon for a certain specific gravity. you also have to consider a few other factors about the beer such as body, then there are grains that effect color.
Asking how much per gallon is simplistic as you are asking how a question like how much sugar for a lemonade, there are endless recipes for lemonade that all have different amts.
Describe the beer you want to make and you will still get a lot of different answers

2 pounds.

Here's a good introductory article in BYO on "the five base malts," how to use them and build recipes around them.

The (sugar) extract potential of most base malts is around 36 points per pound per gallon (ppg). See this table of grains and other fermentables.

So if you want to brew one gallon of beer with an OG of 1.050 (= 50 points per gallon), you'd need 50/36=1.4 pounds of (malted) base grain (barley, wheat, rye, etc.). Since your mash efficiency is less than 100%, say 80%, you need to use a bit more of course:
1.4# / .80 = 1.75# of that grain for your gallon of 1.050 beer.

If you were to make 2 gallons of that same 1.050 beer, you'd need double the amount of grain:
2 gallons * 50 points per gallon = 100 points or 3.5# of base grain at 80% efficiency.
