   Hi Guys.
   
   After 8 successful Mini-BIAB brews I decided it was time to record my process and upload the result to Youtube.
   
   I'm sure there are a few things I do differently to others but it works for me.
   
   Feel free to take a look and let me know what you think (1st ever vid so a bit basic lol)

   I like the video. Just the right amount of information. Also interested in pot size. Looks like a 15 litre fermenter. Could be a 19 litre pot

   Hey Ralph, thanks for making the guide. I've got a 70L kettle and have been doing some large VIF brews lately. I really want to brew more often though so I can test different recipes, so I think that stovetop BIAB is ideal!
   Thanks, Nick.

   Hi all,
   I'm doing a stovetop 10L brew of a popular recipe I found on Beersmith and just want some feedback to see if I have used the BIABacus to scale the recipe correctly. Here's a link to the Beersmith page:
   
   And here's the BIABacus recipe:

   Hi Scott, thanks for the info I'll have to get that book. This will only be my second BIAB so at this stage I don't really know much about yeasts and what flavour changes they can make. Maybe after a few more brews.

   I really like doing small batches. Small batches are super easy (no lifting, clean up is quick and easy) and your brewday can be accomplished on the stove and in the kitchen sink without little to no blood or sweat involved. As long as you have enough small fermentors, there is no limit to how many small batches you could do. Theoretically, I could line a shelf in my closet with small fermentors and have a solid pipeline full of variety at all times. The problem I run into is with yeast. A...

   I use dry yeast, a new packet for each batch that I do, which is usually a 2-2.5 Gal batch.
   
   Dry yeast is pretty inexpensive but most importantly, I can accurately measure dry yeast for the correct pitching rates.
   
   I tape up the packet of unused dry yeast and put it in the fridge. I just brewed my third small ale batch over the weekend from the same packet I first opened on aug 15th - that's 10 weeks - and the morning after pitching the last batch, I observed fermentation as active as the...

7. Heat loss during mash

   Hi. I am on the cusp of moving from extract/steeping grains brewing to mini BIAB. One question I have is regarding heat loss from the pot during the mash. I have ordered a 20l stock pot and was wondering how well a vessel that size typically retains mash temperature? Do you need to keep a constant watch on the temp over the 90 minutes and fire up the stove for a couple of minutes every now and again to keep the temp relatively steady? I have watched the short video posted in another thread...

   Is be giving it a go just with wrapping up the pot with a sleeping bag or yoga mat first.
   
   Losing a few degrees over the course of a 90 minute mash won't make a massive difference.

   Brumpj, if your Barrel is wood, it will release a bit of Pressure, so, the fill should be very close to full, as the headspace can be 7-10mm
   
   If the Barrel is a Corny Keg, the fill should stay around 25mm or 1 inch below the Gas fill tube.
   
   Also, the 20pt-uk volume will fill 1-case of 24 bottles of US 12oz/354ml beer bottles.

    Hello!
    
    First, please let me introduce myself - I am currently a kit brewer (therefore, of course, 5 gallon). This does not suit me because the brew length is too large based on my consumption meaning I brew less frequently and, while still honing my technique, have less-than-ideal brews to drink. The knock on effect is the excitement of variety - the very thing that got me into homebrew - is not something I get with my current brewing given the infrequency with which I brew. The solution that...

    A lot of what Josh mentioned above I would agree with except I don't think brewing a small batch in a large kettle is a problem in our situations. It would be if you left the lid partially on during the boil but not otherwise. A good rolling boil for 90 minutes will see any nasties easily carried out of...

    55 g of rice hulls (is this necessary for such a small batch? - and how does it affect the water volume for BIAB?)
    
    Rice hulls are used to prevent stuck sparges in traditional brewing. They are not really used in BIAB as far as I know. If you end up using them, I'd suggest they go in the bag first and then put your grain on top of the hulls.

    HIya, thought i would post my first BIAB brew. I have previously made a brooklyn brew shop beer, but have no other brewing experience.
    
    I decided to brew 1 gallon of a Single Malt and Single Hop (SMaSH) version of the ‘standard’ All Amarillo APA. (I know strictly speaking it should be called Mo/Am, but AMMO sounds cooler) ;)
    
    Although my glass demijohn holds 3.78L, I decided to aim at 4L. This meant using;
    
    7.92L water, (5.92L at the start, and 2L added before the boil)
    1160g Maris Otter Malt...

    Thanks PP, I should have explained myself better - I guess what i mean is, Is it possible to produce a 'full sized' 23L brew, with my 20-26L(ish) boiler? Or is this just going to open a can (or should that be 'boiler full') of worms??? ;)
    
    But anyway, I opened the last two bottles the other night (I gave the majority say to friends and family) - and heres the 'money shot; ;)
    
    thanks everyone for your help and support :salute:
