Brew in a Bag (BIAB) Down Under – BeerSmith Podcast 10

by Brad Smith on February 24, 2011 · 14 comments

From half a world away in Australia, Patrick Hollingdale is my guest for this week’s episode. We talk about the Brew-in-a-Bag (BIAB) all grain brewing technique that started in Australia but has become popular worldwide. BIAB lets an all grain brewer start with nothing more than a large pot and grain bag and brew a full all grain batch in a single vessel (the boiler).

Topics in This Week’s Episode (35:15)

  • This week my guest is Pat Hollingdale from BIABrewer.info – one of the early brewers who helped develop the BIAB technique in Australia.
  • I talk briefly about the BeerSmith Blog – where you can find a lot of articles on home brewing including BIAB techniques
  • We talk about home brewing in Australia which is incredibly popular – they are actually the #2 English speaking country for home brewing in terms of overall popularity
  • Pat introduces BIAB brewing which involves doing the mash over heat in the main boiler using a full boil mash and then lautering with a simple grain bag.
  • He talks about the equipment to get started – nothing more than a full boil pot (about 9 gallons for a 5 gallon batch) and a large polyester grain bag.
  • We talk about the BIAB process
  • Pat discusses the very high water to grain ratio used (essentially the full boil volume plus more is used for the mash) and how that does not necessarily hurt the efficiency of the mash or lead to off flavors.
  • We talk about formulating a recipe for BIAB
  • Pat discusses some of the advantages of BIAB – including lower cost of equipment (its all done from a single boiler) and less cleanup.
  • I have a detailed article on BIAB brewing if you want to learn more and Pat mentions BIABrewer.info and the AussieHomeBrewer forum as two places to find more information

Thanks again to Pat Hollingdale for getting up early and agreeing to do the interview!
