Brew-in-a-Bag (BIAB)

As I said in the first post about National Homebrew day, my brewing method is based on the BIAB method described by ‘Thirsty Boy’ on the Brewing Network’s forums. I have put together a few shots of my brewing day, just to compare to Justin’s more normal home-brewing set up. Please note that Justin brews 10 gallons per batch, compared to my 3.3 gallons – it may be difficult to scale the BIAB method much above 5 gallons, or so I hear.

The usual procedure in home brewing is to gently mill your grain – taking care to crush the grain rather than grind it, as the husks should be kept as entire as possible. These are put into a mash tun – usually some sort of picnic cooler with a manifold of one type or another at the bottom to allow drainage of the mash. Water is heated in the brew kettle to a strike temperature considerably above the mash temperature – it will decline when mixed with the milled grain. The mash is allowed to rest for about an hour. The mash mixture is then drained – the first runnings are ‘recirculated’ back into the tun, to ensure clear wort. Additional hot water is poured into the mash tun to ‘sparge’ the grain – wash out remaining sugars. This wort is then boiled with hops, and fermented.

In contrast, here is the method I use:

  1. BIAB has turned out to be a great brewing method for me – I used to batch sparge but now have over 50 BIABs under my belt.

    Just a quick tip re the doughing in. You will find it easier to add your water to your kettle first, raise it to strike temperature (for a standard sized BIAB usually about 2 degrees above your mash temperature,) add your bag and THEN pour your grain in. You’ll have no doughballs this way and no heavy stirring to do either.

    Hope this helps and all the best from down under,
