Using Maxi-BIAB to Brew a 'Single Batch' Mini-BIAB.
by Ralph deVoil (Ralph)
What is MaxiBIAB?
MaxiBIAB is a Brew In A Bag, All- Grain (or “All Mash”) method which is useful for making a full- sized batch where the kettle volume is less than the usual 23 L brew length. It is also a relatively simple and effective means for a novice brewer to try All- Grain brewing at full- scale early, so without the annoyance of small batches or a half- empty fermenter. Ordinarily, the de- facto standard brew length is around 23 L, MiniBIAB is around 13 L, but brewers can use the MaxiBIAB method to make full- sized 23 L batches in the same cheap and commonly- available 19 L stockpot they use for MiniBIAB.
MaxiBIAB involves sparging and post- boil dilution, processes which sound complex, but are really quite simple while also lending some clever advantages to the novice and experienced brewer in extracting decent efficiency and eliminating most of the reliance on brewing software to calculate volumes, temperatures and concentrations, actually making brew day simpler and much less hassle.
MaxiBIAB is very similar to MiniBIAB, but with a couple of simple tweaks, those smaller batches are a thing of the past and all that a MiniBIAB brewer requires is a food- grade 10L bucket and a common domestic kettle (about 1.5- 2L is fine).
Cost- For any brewer already making kits, extracts or kits & bits, even MiniBIAB, upgrading to MaxiBIAB is trivial (see equipment below).
Simplicity- As with most BIAB brewing, the actual operations are very simple- compared to traditional 3-V brewing the method and equipment are both trivial, but the equipment is also readily- available.
Easy- Most of the anxiety and fiddling around in hitting volume and Specific Gravity targets are a thing of the past.
Space- Just the stockpot and bucket, often one even fits inside the other.
Low- risk All- Grain- MaxiBIAB is one method to try All- Grain brewing at full- batch scale that doesn't have significant equipment outlays or doing multiple batches to fill the fermenter and just like MiniBIAB, even if the brewer tries MaxiBIAB and for what ever reason doesn't like it, there's no great loss or expensive and now- useless pile of equipment in the shed/ garage.
