If you’ve been following this blog, and have tried your hand at homebrewing, you know that you can make some truly excellent beers using extracts, specialty grains, and hops.

You should also have realized by now that good, solid basic techniques and practices, such as religious sanitation, and a few others, can result in good beer and more fun than watching back-to-back Star Wars reruns (well maybe).

And as I’ve written before, there’s really no point in being an all-grain snob. Really none at all. But that doesn’t mean that making an all-grain brew isn’t a fantastic challenge. In my previous post, I discussed the basic theory of all-grain brewing. Today, we tackle the how-to, starting with equipment.

When it comes to equipment, one option is to go full hog. Buy larger brew kettles, get a hot liquor tank, convert a cooler into a mash tun, and buy various other bits and pieces to construct a state-of-the-art all-grain home brewery. John Palmer’s site has a nice setup that you can take a look at here. There’s one problem though. Full hog = full price. Building a three-tiered, 50 liter electric pump brewing wonder-machine might be awesome, but for many homebrewers, it’s just too costly.

Even if you have the money (you lucky bastard), you may not have the space. So if you’ve got a tiny apartment (or bank account), is all-grain brewing out of reach? Not at all. There’s a quick, easy, and cheap way of trying your hand at brewing all-grain beer.

This method of brewing is called brew-in-a-bag or BIAB. It’s an excellent way of getting into all-grain brewing without massive investment. In fact, if you’ve got the equipment I’ve listed in my basics and nice-to-have equipment posts, you’re just about ready to go.

BIAB Basic Equipment

Here’s what you’ll need for BIAB:

The Bag.

The obvious one.

As the name suggests, you’re going to be using a rather large mesh bag. Most homebrew supply stores sell these, and they’re generally made from voile mesh (the kind old folks made inner curtains from) and can carry up to (or more than) 5-6 kgs of grains.


 Make sure you buy a bag that is large enough to line your brew kettle (see below), and that it is strong enough to hold weight (flimsy ain’t going to do it). So if you want to make your own, make sure to double stitch or something (I don’t know anything about sewing. Sorry.).

A good way of knowing how big your bag should be is to use your brew kettle. If the kettle can fit inside the bag and leave enough space for the bag to be tied, your bag is spot on. Speaking of kettles..

Bigger Brew Kettle

If you haven’t yet bought a bigger brew kettle (shame on you), you will definitely need one for BIAB.

I recommend a kettle of at least 30 liter capacity. Try for a nice, big stock pot made from either aluminum (cheaper), or stainless steel (bling-ier).

Avoid pots that are very wide and squat. It’ll be difficult to maintain a good rolling boil in those (not to mention finding a bag that will fit).

Small Metal Colander

Viole mesh is a great fabric for BIAB, but it isn’t 100% heat resistant. So to keep the mesh off the bottom of your brew kettle where it can get scorched, I recommend placing a metal colander upside-down in the kettle.

That will keep your bag safe and in one piece for multiple brews.

Binder Clips

Yep, everyday binder clips from the stationary shop. You’ll use these to secure the bag to the sides of the kettle, and in turn, prevent the bag from falling into the kettle, thus making it difficult to retrieve at the end of the mash.

Brew Spoonr Clips

A nice, long handled brew spoon, preferably with holes or slots (also known as a mash paddle), is useful for mixing in your grains and preventing clumps and dough balls from forming.

Digital Thermometer

Keeping an (accurate) eye on your mash temperature is crucial for all grain brewing. Try and get an accurate digital thermometer that gives you an instant reading of the mash temperature.

A probe-like thermometer like the ones used to measure the inside of cooked meats (yum) can also be used successfully.

Nice-to-haves: Grain Mill.

If you’re going to be doing more all-grain brews, the ability to mill your own grain is very convenient.
Of course, you can have your malts pre-milled by the homebrew supplier, but milled grains don’t keep fresh as long as whole one.
So if you buy pre-milled, use the malts as soon as possible.
Well, that’s it. Now you’re ready to tackle all-grain brewing with BIAB! Next time, I’ll discuss your first all-grain, BIAB recipe for a hoppy, refreshing American Pale Ale. See you then!
