Hey again guys,
I am planning my fourth recipe atm, but I keep getting stuck on some details. I am new to brewing and therefore, I want to try to explore LME instead of DME this time. I am planning a simple recipe, but the IBU calculations are giving me headaches.
I want to use some X amount of LME (in KG). I only have access to a 10L pot, so I will add 8L of water to my boil. Because of this, I need to calculate how much LME I wanna boil to get a pasteurized wort for my hop additions, and then later on add the remaining LME at flameout.
I had the recipe all done and tidy, but now when I change a large part of my LME to late additions the IBUs go through the roof. Could someone explain this to me, and tell me what to believe?
My recipe (WIP):
19L batch
8L water in the pot
The manufacturer reports 80-82 brix for the LME. I don't understand this number as this translates into massive SG, which recipe calculators can't even take in as the yield is larger than 100%! So Instead, I calculate with 300PKL (36PPG) as some average number for LME.
This gives me the following calculations if I wish to have a pre-boil gravity of around 1.040
LME in boil = (40 points * 8L) / 300PKL = 1,07Kg so about 1Kg.
Fermentables:
Hop additions (a bit unorthodox perhaps but it is all my left over pellets):
Yeast: US-05
Brew father reports this as 114 IBU, Brew target some 90. Is this true? Considering I top of in fermentor to 19L? Or am I missing something. I am aiming for some 35-50 IBUs and perhaps just above 5% abv.
Also, feedback on the recipe overall? As mentioned, I got the hops and these are all I got. The LME is still to be purchased and so is the yeast. So nothing is final except the hops, though their schedule could be altered.
