Things have, in fact, been going on despite all appearances.
I've been working on a utility for BrewCalc that will enable the user to scale recipes up or down. It will even adjust amounts of your ingredients based upon extract efficiency. I have the grain portion of this sheet worked out, now I'm working on adding the hops portion. Here's how it will work when its finished: The user will enter a recipe that he/she has been given in the first worksheet ('OG, IBUs, ABV%, etc.'). The user will then click on the Scale Up/Down sheet where figures will be calculated based upon batch size, extract efficiency, and new hop utilization figures (as per Tinseth). The end result will be the new amounts for each ingredient listed in the original recipe.
Secondly, I've been putting together some new charts as of late. I've been working on graphing out similar styles on a graph whose Y-axis is Original Gravity and whose X-axis is IBUs. These graphs show ranges of OG/IBUs and even show where the intersections are of similar styles. I only have a few complete thus far, but I'll begin to post them as I continue to work on them.
Lastly, I just took the BJCP exam for the second time last night. It was as long and arduous as I recalled, though I suspect I bettered my score substantially this time around. I'll find out exactly how I fared in the next three to four months. That being said, I'm a little burnt out on technical homebrewing information right now, which means that Tech Tues will have to get pushed back to next week once again. Hope to see you then.
