1can LME

[JoanofArc]

What more do I need to make 5 gallon of wort? How much DME or dextrose do I need to add?

What size can?
What kind of beer do you want to make?

If 3.3lbs Briess Golden Light LME with Nottingham, you are looking at about 2.25 ABV.
That's beer.

3.3 lbs Briess Golden Light DME gets you up to about 5 ABV.

YMMV
