   Hi everyone
   
   I've been using BIABacus successfully for a few years now. I've recently been wanting to get more out of my brew days however space and equipement limitations have made it difficult. A Brulosophy experiment looking at full vs partial boil volumes and adding water the to the fermenter prompted me to try brewing a concerntrated wort and splitting it into two beers.
   
   I'm attempting to use BIABacus to do this however when I enter something in section W, water added to fermentor, it...

   Wow thanks Mally.
   
   I checked this just now by changing the gravity of ambient wort of the full mash to match the partial mash (prior to adding water) and the hop amounts were exactly the same. I never considered hop utilisation reduces the thicker the wort gets... I guess I should've actually studied the tinseth formular...
   
   Based on this I'm considering adding the full amount, or atleast part of the water prior to boil to reduce the amount of hops I'll need so the recipe will be more efficient.

3. Less hop Aroma in BIAB than other methods

   Hi all,
   
   Just curious. Has anyone else noticed less hop aroma from late addition & dry hopping with BIAB? No matter what I do, I feel that my hop aroma is restrained with this method (I can get beautiful malt aroma).
   Perhaps it is from the cold crashing or the extra protein from the extra trub. I no sparge BIAB.
   
   Let me know if you have experienced this!

   Sounds like the discussion is really about the chilling method you use. That's why, when trying to copy a recipe, it's great if you can get details of the chilling method. (Have a read of this .) Often you can't and most recipe software doesn't have a place where you can state the method. The BIABAcus has a place for that in Section G but with some of today's hop schedules, sometimes you really need to add some explanatory notes in Section I as well.
   
   There's a lot we don't know about hops....

   I've wanted, for a long time, to write a procedure for using the BIABacus to partigyle. One main problem is that I generally do not brew high gravity beers ( Sarah Sarah has forced me several times) and the grain bill on those done has not lent itself to being re-used for a lower gravity brew e.g. Cherry Chocolate Stout! Since tasting Rocky Ridge's absolutely beautiful Rock Juice, I now have the desire!!!

   I use no-chill cubes so I do not go straight from the boil kettle to the fermenter.

By that time, the wort in the cube is just the right temp to go into the conical fermenter and all...

   Taking early steps to manage trub would be better, as mentioned by others with bag and sock porosity etc. I started with poor quality bags and eventually made up a few fine mesh Swiss voile bags (thank you beachbum/bribie for the simple circle design) the difference in trub was massive. Added whirlpooling at the end of boiling and slow transfer to the cube, again big improvement.

   After 2 years of traditional mashing, I'm coming back to the BIAB fold. :o
   
   I am wondering if the BIABacus provides any way to take into account the IBUs from a hopstand. For example, in a Blonde Ale recipe I am looking at, there is a 30-minute hopstand before chilling and pitching yeast. According to BeerSmith, the 60-minute boil hop addition contributes 17.9 IBU and the 30-minute hopstand contributes 6.9 IBUs, so for this recipe the hopstand contribution is significant (28% of the total...

   Last post

   Dave.....A 30 minute hopstand will impart aromas plus very few IBUs .Just like adding hops at flameout. I will try to find the article I read on adding hops at these time and post the link. If you are looking for IBUs , try adding around 15 minutes. At that time you will get 50% flavor & 50% aroma utilization .

10. 90 Minute boil with no early hops?

    First post by Primavera, 1 year ago

    If there are no hop additions planned before :20 remaining, is it still necessary to boil for 90 minutes?
    
    I understand why hop additions happen after the first 30 minutes - wouldn't it be a time and propane saver to cut the boil to 60 minutes when only hopbursting?

    Last post

    There's a few things (Edit: actually, a lot of things) worth understanding here.
    
    - Hop addition times are really not that relevant to boil time. For example, if you add x grams of hop A at 90 mins versus adding it at 60 mins, there is very little difference in the end result. So, boiling is not really about hops.
    - A home-brew 90 minute boil is not the same as a craft brewery 90 minute boil. Certain techniques might be employed in a craft brewery that are unavailable to us.

Across the board there were discrepancies of up to 30%. Glenn Tinseth was on hand to discuss the results. What I found really interesting is that Glenn said that his formulas are based on whole leaf hops and not...

    I realize there is already a ton of documentation on the inaccuracies of ibu calculations. What I found most interesting is the fact that Glenn used whole hops in his testing and believes that once the hops were covered in the sugars in the wort that hop oil extraction dropped and that pellets are probably more efficient.

    I have never read that you ' can't ' use dry yeast in a starter. I think the general consensus is just that it is unnecessary, since a dry yeast pack has more than enough cells to ferment the standard 5 or 6 gallon batch, where as with liquid yeast the count is lower, and more variable.
    
    In your situation I would do the same thing, especially if yeast is hard to come by. I've noticed around these parts the price of dry yeast has gone up quite a bit over the past couple years too, as well as...
