I see version of this question has been asked, so apologies for the repeat but its never quite answered in the way I need.
I made a batch last night and noticed half way through the process that lowering the boil size had seriously dropped my IBU's (40 vs 8). My pot size limits me to about 5L once the hops are in. Its a simple recipe using LME, DME, dextrose and fresh hops. The recipe didn't address when to add the sugars, only the hops so I had to wing it. I boiled 2/3 hops for 60 mins, added the LME at 40 mins into the boil, hops at 7 mins and the DME after flame out.
After reading around I am still left with a couple of questions:
- Can hopes add bittering without sugar? I've made hop tea before using only water.
- Is my IBU reduced to the same extent if I did not add LME until late in the boil?
- Is there a formula for figuring this out as I now have no idea what I just made. My only gauge is that the wort had a strong bitter aftertaste.
Thanks for your help.
