All-Grain Brewing Guide: Step Up from Extract to Advanced Homebrewing

What is All-Grain Brewing?

All-grain brewing means making beer entirely from malted grains rather than using pre-made malt extract. You’ll mash crushed grains in hot water to convert starches to fermentable sugars, then lauter (rinse) to collect sweet wort. It’s more complex than extract brewing but offers complete control over your beer’s flavor, body, and character.

Why Go All-Grain?

• Cost savings – Grain costs 50% less than extract per batch
• Unlimited recipes – Access to thousands of grain combinations
• Fresher ingredients – Grain stays fresh longer than extract
• Better beer – More control means better consistency and flavor
• Creative freedom – Design your own recipes from scratch

Additional Equipment Needed

Beyond basic homebrew equipment, you’ll need:

• Mash Tun – Insulated cooler with false bottom or bag

False bottom
Krome AG405 Stainless Steel False Bottom for Homebrew Pot: 12"
Holds the grain bed off the bottom so wort can be drawn from underneath it. This is the part that makes step 5's sparge possible without the stuck sparge listed at the end of the article.

Or the bag instead
Brew Bags Reusable 3 Pack, 26"x22" Fine Mesh Strainer Bag
Brew-in-a-bag skips the mash tun entirely: mash in the kettle, lift the bag out, boil. It costs a few points of efficiency and saves the whole hot liquor tank and sparge apparatus.

• Hot Liquor Tank – Second pot for heating sparge water
• Larger Brew Kettle – Minimum 8 gallons for 5-gallon batches

Kettle with the fittings already in it
Northern Brewer MegaPot Stainless Steel Brew Kettle with Volume Markings
Why it fits
Volume markings are the feature that matters most here, because step 5 asks you to collect 6-6.5 gallons and every efficiency calculation in all-grain brewing depends on knowing your volumes rather than estimating them.
Limitations
Expensive for a pot, and a bare kettle still needs a chiller and a way to hold the grain bed before it can brew all-grain on its own.

Same job, weldless fittings
CONCORD Stainless Steel Home Brew Kettle Stock Pot with Weldless Fittings
Why it fits
Ships with a ball valve and thermometer already fitted, so wort is drained through a tap rather than poured from a full boiling pot. That is a genuine safety difference at 6 gallons.
Limitations
Weldless fittings seal with an O-ring and will eventually weep if the nut is not kept tight. They also add crevices that need dismantling to clean properly.

Or replace the whole three-vessel setup
Kegland 35L BrewZilla, 9 Gallon All-in-One
Why it fits
An all-in-one electric system mashes, recirculates, sparges and boils in a single vessel, which removes the mash tun, the hot liquor tank and the burner from the equipment list above at a stroke.
Limitations
It is a larger single purchase than any one item on that list, and 120V electric heating brings a 6 gallon volume to a boil more slowly than propane.

• Wort Chiller – Immersion or plate chiller speeds cooling

Immersion chiller
Northern Brewer Copperhead Copper Immersion Wort Chiller
Copper conducts heat faster than stainless, which is the whole reason to pay more for it. Drops into the kettle at flameout; nothing to dismantle afterwards.

Plate chiller
Ferroday 20 Plate Wort Chiller, Stainless Steel Brazed Plate Heat Exchanger
Chills wort as it flows out of the kettle rather than in a batch, so cooling happens during the transfer. It needs a pump and a back-flush routine, which an immersion coil does not.

• pH Meter or Strips – For monitoring mash pH
• Grain Mill – Or buy pre-crushed

Grain mill
FERRODAY Malted Grain Mill, 2 Roller Stainless Steel
An adjustable two-roller mill cracks the kernel while leaving the husk intact, and the husk is the filter bed step 5 drains through. A gap you control is also the first lever to pull against the low efficiency listed under common issues.

The All-Grain Process

Step 1: Crush Your Grains

Crush 10-12 lbs grain depending on recipe. Grain should be cracked, not pulverized. Pre-crushed works fine for beginners.

Step 2: Heat Strike Water

Heat 4-5 gallons water to strike temperature (usually 165-170°F). This will drop to mash temp (148-158°F) when you add grain.

Step 3: Mash (60-90 minutes)

Add grain to heated water in mash tun. Stir well, check temperature (target 150-154°F). Maintain temperature for 60 minutes. This converts starches to sugars.

Step 4: Mash Out

Raise temperature to 168°F for 10 minutes. This stops enzyme activity and makes wort flow easier.

Step 5: Sparge

Slowly rinse grains with 170°F water while draining wort into brew kettle. Collect 6-6.5 gallons total wort. This takes 45-60 minutes.

Step 6: Boil, Cool, Ferment

From here, process is same as extract brewing: 60-minute boil with hops, cool to 70°F, pitch yeast, ferment for 1-2 weeks.

Mash Temperature Guide

• 148-150°F – Highly fermentable, dry, crisp (IPAs, Saisons)
• 152-154°F – Balanced (most ales)

Check your gravity as you go
Brix Refractometer with ATC for Wine Making and Home Brewing
A refractometer reads gravity from two drops of wort rather than a full test jar, so you can measure first runnings and pre-boil gravity mid-brew without losing volume. Note that it needs correction once alcohol is present, so keep a hydrometer for finished beer.

• 156-158°F – Fuller body, sweeter (Stouts, Scottish ales)

Common All-Grain Issues

• Stuck sparge – Grain bed too compacted, flow stops
• Low efficiency – Not extracting enough sugar from grain
• pH too high – Affects flavor and extraction
• Inconsistent temperatures – Affects final gravity
