Ok so I am the newbest of newb at brewing and just now delving into the information. I want to try to reproduce the ales that would have been around in the 10th-14th century. As I understand it there were no hops used in this time period and instead were bittered using various herbs and spices for instance wormwood. I have never done brewing of any sort but from what information I have gathered over the past 2 days is that an extremely simplified brewing process goes as follows " Boil water, make mash, drain wort, sparge, boil wort, add spice, cool, put wort into fermentation container, pitch yeast." I understand (or atleast think I understand) that the boiling of the wort is to kill any remaining bacteria because it reaches at least a temperature of 160F. Also because that is the temperature that are best for hops to be added (?).
What is to prevent me from the following process " boil water, make mash (mash includes some spices), drain wort, sparge, cool., into fermentation container, pitch yeast" If the water to make the mash goes in at ~175 degrees would that not sanitize the wort and grain itself? If the herbs that I plan to bitter with (havent figured out what herbs and spices yet but it will not be hops) do not need me to do it at a specific temperature can I safely skip the boil step?
This is the first questions I have asked anyone on brewing so dont bust my balls too bad (unless you are into that sort of thing). There is such a thing as stupid questions and I plan to ask them all. Thanks for any help.
