Liquid extract has about 36 ppg or points/pound/gal. That means that one lb. of LME in one gal. of water gives you an OG of 1.036. You have 5 kg or about 11 lb. Multiply that by 36 and you have a total of 396 gravity points. Divide that 5.5 (gal., roughly 23 L) and you get 72, so your OG would be 1.072. Because you're doing a concentrated boil, your hop ...

One way to evaluate beer bitterness is through the IBU/OG ratio. In your case that would be 151/63=2.396. Now this is hugely bitter! I don't know which style of beer you are trying to brew, but to take some guidelines, the Imperial IPA style (taken as an example of extreme bitterness) should have the following parameters: OG: 1.070-1.090 IBU: 60-120.

But, yes, we're really trying to control the bitterness:sweetness ratio in the consumed beer, and FG ...
