1. 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!

   Hi Scott quite the opposite it may have had more punch to it but it only made it more drinkable it's quite difficult to describe but it just oozed aroma and freshness a bit like the difference between opening a fresh bag of hops along side a bag that's been kicking around for a while even though both batches used a share of the same packs of hops.

Had to head out of town to see a sick uncle so I put my fermenter in my spare fridge. It was at my expected og.

   I have brewed a lot of beer using the 3 vessel method, and I've completely revamped my brew rig to a single vessel, brew in a basket design. I have a picture but it won't load....file size too large, so here is a diagram of my Keggle with the grain basket in it, and the way I am recirculating is via a vertical pipe with holes in it. I've ordered a custom grain basket, 800 microns stainless steel mesh, that just fits into the opening I cut into the Keggle, and I've got feet on the basket so...

   Interesting design, any fear of creating channels where the wort returns through the pipe? Seems there are a number of people moving to a basket setup versus fabric filter these days. Good luck with the system, definitely post back here after you have a go with it.

   Hey Guys,
   
   I'm sure this has been addressed before but I couldn't find an answer by searching. The recipe I want to brew calls for a hop stand with 57g of 10.3% AA Centennial, starting 10 mins after flame out and steeping for 20 mins. I'm not sure how this should be entered in the BIABacus especially regarding target IBU calculation.

   It’s a reminder about “recipe integrity” discussed elsewhere on this site. The variables in play during a brew day seem innumerable and any data that could make a difference in the outcome (beer) should be included.
   
   I am working toward using my Inkbird temperature recorder to eventually give a time / temp graph that has tick marks for when things changed. eg. stirring mash, end of mash mashout period, pulled bag,, hop additions, FO, post knockout additions, transfer from...

My first batch was based on a recipe entered into BIABacus PR1.3 T , and the second batch will be the same recipe but entered into PR1.3 U . However, I am seeing a discrepancy between the 2 versions for the final gravity (as well as the predicted ABV). For PR1.3 T , FG is 1.012 (7.8% ABV) while PR1.3 U shows 1.018 (7.0% ABV). There is not much in terms of fermentables: 78.6% pils malt and 21.4% cane sugar -- for both...

   Dang, you're smart, MS! I have it set to 84% in T and the default 75% in U :headhit: Thanks!
   
   Now I have to remember where the 84% came from -- the recipe is from BCS so I'll need reread the previous discussions on using it with the BIABacus.

   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.

   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.

    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 .

    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.

    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...

    I haven't tried it before but thought I'd give yeast washing/re-using a go. I've got a bottle of my old yeast which has been washed in the fridge, I've gotten rid of any trub and any top floating beer/water to leave me with about 200mls or so of yeast slurry.
    I only do small batches of around 2.5G/10L (into fermenter) so I was wondering how much of this yeast slurry I should pitch into my next brew (OG ~ 1.050)?
    I tried using the Mrmalty.com website but it suggested I only need 43 ml, that's...
