Will scaling a recipe lower to at least one gallon (i.e. dividing the quantity of each component by 5) create a pretty close approximation from the outcomes of a complete 5 gallon batch? What are the additional factors in brewing this type of small batch?
Let me perform some small experimental batches within the winter, utilizing a 2-gallon stockpot around the stovetop rather of my usual brew kettle with an outside burner setup. I wish to make certain they are pretty near to exactly what a 5-gallon would finish up like (esp. taste) in order to decide whether to go forward with full batches of those recipes early in the year.

The majority of things will scale all right linearly, the exception being hop utilization. Wort gravity impacts utilization the greater the gravity the low the employment. For this reason extract brewers that do not perform a full wort boil get less utilization that the full wort boil the gravity from the wort during boil is greater (then they add water after boil to dilute to focus on gravity).
I am unsure if going from 5 to at least one gallon have a important effect, however, you can enjoy with this particular calculator to determine what goes on. Many brewing software packages can perform this for you personally. Regrettably many of these are just techniques to estimate the ultimate IBUs. The only method to determine actual IBUs is to possess a lab measure it.
