Good enough for my chickens good enough for me. Honestly this is what makes it fun for me just winging it following recipes and rules takes the fun out of it for me. So far I have done pretty good I haven't thrown away anything. The only thing I might throw away is the quick brew stuff I bought from more beer that stuff was no good well to be fair one was ok but one sucked don't ask me which was which
Update for anyone who cares. Everything seemed to have turned out right except the beer is extremely bitter. I even tried mixing 50 50 with another Beer and still it was way too bitter. The hops I used said low alpha acids in the 5s Gemini and cashmere but I guess I used way too much in my boil so I am taking the beer and I will distill it today and see what I get. I'll update later
Not making a recipe usually results in wondering what went wrong. It would have taken < 2 minutes to figure out how much hops of the alpha acid you bought should actually be used to get the result you want.
How many ounces of hops for what volume of brew? If not over hopped, wondering if bitter taste could be from tannins from the grain & chaff.
This comment about tannins is pretty much spot on as your pH was most likely way off (high), combined with all the chaff and straw, it would be tannin city. Again, taking < 2 minutes to calculate the amount of acid to add to your mash and/or boil might have saved the beer.
There's a reason malt is made with plump kerneled grain and is cleaned and rinsed in the steeping process.
Why waste all the time/effort and money to do this sort of thing when it can be done right (even with feed grade grain) with very little effort? To me that's not fun.
Repeat the whole exercise (make beer with feed grain grain) but this time use a beer recipe calculator and a mash water calculator to determine the amounts of grain, water, hops, yeast and if (how much) pH correction is needed. You'll have a better chance of success and won't waste your time and money.
To get rid of the chaff/straw, try dropping the grain on a tarp in front of a fan (poor mans fanning mill). That's what I do (in addition to stirring) to deculm my home malted barley and wheat. Also make sure your homebrew mill is actually crushing the grains appropriately.
Your mash didn’t produce a sweet sugary wort. The hops had nothing to counter act.
He did use some actual malt (5lbs 2-row) and got an OG of 1.045, so there was some of something in there, but most likely used too much hops.
Here's a Brewers Friend screenshot - a best shot at your recipe, though I'm not sure of the volumes, yeast, and hops, etc... but should give you a start for filling in your own recipe. ~30% efficiency is horrible. The high IBU's are with just 1 oz each of the varieties of hops you specified. 74 IBUS @ 1.64 BU:GU, will not be drinkable at that gravity.
Also note the Diastatic Power of 17, well below the recommended level for a mash, though you did add amylase enzyme, which means your grain was not crushed or not crushed appropiately and the mash pH was not appropriate for the enzymes.
