I'm new here. I haven't even started homebrewing yet, but I have a question about using malted grains rather than a malt extract kit.
When using a kit that combines malt extract with specialty grains, the usual approach (or so I have been told) is
1. boil and seep the specialty grains in a bag,
2. remove the grains from the water,
3. bring the water back to a boil,
4. remove the water pot from the burner,
5. add malt extract and stir,
6. return water pot (wort) to a boil for 45 - 60 minutes,
7. add hops,
8. cool wort as quickly as possible,
9. strain wort into a carboy and mix with enough water for five gallons,
10. etc., etc.
Now the question: All else being equal to the liquid extract kit procedure, if I simply boiled specialty grains and malted barley in a grain bag instead of using the malt extract, would I have decent beer from the endeavor?
The reason for my question, unfortunately, is another question: If I use barley that is already malted, why would I have to use a partial mashing process to make wort?
Thanks in advance for your response.
