So I bought all of my hops / grains / extracts to brew this wonderful beer but want to run a few processes by the experts to ensure that I do not eff this up - this one was expensive <60 - obviously mostly from the 1LB of hops!
Here is my situation - I am a beginner with just a few successful batches - and I can only boil about 3.5 - 4 gallons. This specific recipe was prepared with the final volume of 5 gallons (after trub and boil losses) - but essentially starting with 7.5 gallons in the kettle. The recipe states that the ingredients were adjusted in accordance with the boil volume. I have no idea what my exact boil evaporation rate is...
I guess my main problem is trying to reverse the process to recalculate the ingredients based on my boil capacity. At then end of the evening, I gather that I need to pour 5.5 gallons into the primary (.5 gal loss in fermentation trub).
Could I simply steep the grains, add the LME (substituted for DME), add my hop additions at the specified time intervals and then once the 90min boil is complete determine the volume I have? I could do this by marking my kettle in 1/2 qt increments. Then transfer the wort over to the primary and adding the remaining balance in water bringing my final volume to 5.5gal?
How much will this impact the FG and overall taste?
