   Hi guys,
   
   I bottled my first BIAB today and batch primed with Dextrose. So I used the BIABacus which said use 2.7g per 500ml bottle (2.5Vol). which I worked out to be 24.3g as my batch size is one UK Gallon (9 bottles) so 9x2.7=24.3g. Ok.
   
   So just out of curiosity I had a look on the northern brewer priming calculator (after I had bottled) and it suggests less than half of that 5.44g. :nup:
   
   Also I only managed 8.5 bottles as I had a little trouble with my syphon.

2. Back to BIAB - is this kettle too small?

   I'm just getting back to BIAB - and mini-BIAB in particular after falling back to the 3-tier system I've had for years.
   
   This past weekend I bought a 5.5 gal pot to brew 2.5 gal to 3 gal batches with. However, after doing some numbers on the Calculator, I am thinking I should have bought a larger size??
   
   What I was going to start with was a 3 gallon batch of English Bitter with a OG of around 1.037. According to the calculator I will need a mash volume of 7.22 gal !? Maybe I missed something...

   Hi there Opalko and welcome back to BIAB :peace:,
   
   There's been a few developments here recently. For example, The Calculator has been replaced with a pre-release version of the BIABacus. The general principles of the Calculator remain the same however the BIABacus is far more powerful and will in fact do lots of stuff that no other software can do. I have put your recipe into the BIABacus here. BIABacus PR1.3A - English BItter Opalko.xls Before you do anything...

   Hi, I've only made brews from standard 40 pint kits, which I've transferred to corny kegs. I'd like to do a BIAB , but equipment, space and a disability limit me to a 19L stock pot so MINI BIAB's are ideal. but I'd like to keep using my kegs.
   
   Can I make 2 x 9+ litre brews, adding the second to the fermenter a few hours later, possibly even the next day if the temps are equal... ie brew first batch, cool. transfer to fermenter, pitch yeast , brew second 9+ litres, cool, add to fermenter so...

   pyrotech,
   You can also cube your first brew in a 10L cube ( Link ) - I've used when I only had a 15L kettle. Just thinking - you can then do is to put the cube overnight in a fridge and mix it with your fresh/new brew to cool it down quickly?! It should work... :think:

   Hey everybody,
   
   I'm new to this side of brewing and preparing for my first BIAB. I have a few questions (some are probably stupid ones) before I get started in the new year. I have a 32l stovetop boiler (not sure if it counts as mini-BIAB or not) and I'm looking to get ~23l from the brew for a 19l corny (+ a few glasses from the fermenter during kegging :P). I've done a water run and it lightly boils ~30l in about 25-30 minutes from cold.
   
   1) Is there a particular hop bag people recommend?...

   Hi rob,
   I would really recommend that you buy a decent thermometer. I've got 4 cheap ebay & amazon thermometers and two glass thermometers and the temperature difference between them is rather shocking. The one probe type thermometer developed the quaint characteristic of jumping by 5C whenever you taped the probe.
   I'm using this as my main instrument. This one also seems to be rather accurate - I bought it without the calibration certificate.

   i made a 1.25gal starter the other day with 1.5# 2-row and .5# rolled oats (steeped at 170F for 15 min) and when i was done, i had an extremely cloudy wort. comprised of such fine particulate i still got some into my flasks. does BIAB normally have such large amounts of trub, or could it have been the oatmeal? the mesh size on my material i made the bag from is quite a bit larger than the finest sized hop bags, so i crushed pretty darn large. any ideas?

   I'd stick with the calculator, you will find that it is surprisingly accurate and once you have 5 + brews done you can dial in your averages and it gets even more accurate.
   
   As to hops I'd use the Fuggles or EGK or a mix of the two :think: you ain't going to use many with a 2 gallon brew.
   
   Start another thread if you need to post your recipe and someone will check it over.

   Hi All,
   have done my first Mini Biab and have found an unexpected grain flavour to the resulting beer.
   Smells & tastes very much like a open bag of malted grain. Nothing offensive and certainly not an infection.
   Noticed it at bottling and have tried it after 2 weeks and still present.

   ok so perhaps I could do a full boil of the quantity of water and measure the evap or just wait for the next brew and ensure I get the right measurements. Ehh why waste the gas I spose.
   Did check the gravity and it was 1.010,so I'm guessing I missed the o.g. a little but a quick taste indicated it was a better brew than the 1st. I'll try and get another done this week with some additional accuracy.

    I pitched the Muntons Gervin English Ale instead as I didn't really have any other options, and that started fermenting nicely within a few hours. A bloomin' shame, but at least I'll have beer of some sort; even if it's not what I was aiming for.

    I brewed last night with 4.5kgs of grain in 10 or so litres. I took the gravity of the wort prior to boiling, and after 75 mins boil topped up in the fermenter to 12 litres and pitched yeast. Problem is, due to it being close to midnight come pitchig time, I forgot to take the OG.
    
    Is there any way to calculate the ABV ?

    So, is the theory of making a more 'concentrated' wort from grain and then 'diluting' in the FV a reasonable sound one? Glad to hear you are enjoying it all Gyro :thumbs:.
    
    I personally think when you want to get more out of your kettle than a full-volume mash will allow, the rule to follow is to add as much water as soon as you can and allow as much of this water to touch the grain before the boil.
    
    You have allowed as much water as possible to contact the grain from what I've seen. I think...

    Alternatively, I have done 2x 5 gallon batches by starting the second batch 1 hour later and mashing on the counter rather than leaving on the stove. Its a bit more work shifting the pots around, but it can easily be done.

Nowadays I think things a different, BIAB has become mainstream.

    With my 15ltr stockpot I plan on using 2kg of grain so how much space should I allow for displacement in the pot? I don't want to be topping up once I've got the mash on so what starting volume of water should I aim for that would then fill my pot once I've added my grain? Would 12ltrs be enough or could I get away with 13 and not risk overflowing the pot?
