TL;DR

All-grain brewing replaces malt extract with raw grain, giving you full control over flavor, body, and fermentation character. A typical first brew day takes 5–6 hours. You need a mash tun, hot liquor tank, boil kettle, thermometer, and a basic understanding of mashing, sparging, and boiling. Expect a brewhouse efficiency of 60–70 % on your first attempt — that is perfectly normal. This guide walks you through every step, from crushing your malt to pitching yeast, with a timing chart, equipment checklist, and the most common first-batch mistakes so you can avoid them.

Why Go All-Grain?

Extract brewing is a fine way to learn. But at some point, every homebrewer feels the pull of all-grain. The reasons are straightforward:

If you have brewed a few extract batches successfully and understand basic sanitation, you are ready. For a detailed comparison of both methods, see our guide on All Grain Vs Extract Brewing.

Step-by-Step Walkthrough

Step 1: Calculate and Heat Your Strike Water

Strike water is the initial water you add to the mash tun. You need enough to achieve your target mash thickness — typically 1.25–1.5 quarts per pound of grain.

For 11 lb of grain at 1.33 qt/lb:

11 × 1.33 = 14.6 quarts ≈ 3.65 gallons

The strike water temperature must be higher than your target mash temperature because the cool grain will absorb heat. A common formula:

Strike Temp = (0.2 / R) × (T_mash − T_grain) + T_mash

Where R is the water-to-grain ratio in quarts per pound, T_mash is your target mash temperature, and T_grain is the grain temperature (usually room temp, ~68 °F).

For a target mash of 152 °F with grain at 68 °F and R = 1.33:

(0.2 / 1.33) × (152 − 68) + 152 = 0.15 × 84 + 152 = 12.6 + 152 = 164.6 °F

Heat your strike water to approximately 165 °F. For complete sparge volume calculations, see Sparge Water Calculation Guide.

Step 2: Mill Your Grain

If you own a grain mill, set the gap to 0.035–0.045 inches. You want the husks cracked open — not shredded into flour. Intact husks form the filter bed during sparging. If the grain is too finely crushed, you will get a stuck sparge.

If your local homebrew shop (LHBS) offers milling, use it. Tell them it is for all-grain batch sparging; they will set the gap appropriately.

Step 3: Dough In (Mash In)

Add your strike water to the mash tun first, then slowly pour in the grain while stirring. This prevents dough balls — clumps of dry grain surrounded by water that never convert properly.

Stir thoroughly for 2–3 minutes. Check the temperature. You should be within 1–2 degrees of your target. If you are low, add a small amount of boiling water. If you are high, stir and wait — temperature drops are easier to manage than temperature raises.

Close the mash tun lid and set a timer for 60 minutes.

Step 4: The Mash Rest

During the mash, enzymes in the malt — primarily alpha-amylase and beta-amylase — convert starches into fermentable sugars. Temperature determines the balance between fermentable and unfermentable sugars:

For this recipe, 152 °F produces a balanced pale ale. For a deep dive into enzyme activity and mash temperatures, read Mash Temperature Guide Enzyme Activity.

Check the temperature at 15 and 30 minutes. A well-insulated cooler mash tun typically loses only 1–2 °F over 60 minutes.

Step 5: Vorlauf

After the mash, open the spigot on your mash tun and collect the first runnings in a pitcher. The first wort that comes out will be cloudy with grain particles. Gently pour it back on top of the grain bed. Repeat until the wort runs reasonably clear — usually 1–2 quarts.

This step sets the grain bed as a filter, producing clearer wort.

Step 6: Sparge

Sparging rinses residual sugars from the grain. For your first batch, batch sparging is the easiest method:

  1. Drain all first runnings into your boil kettle.
  2. Add your pre-heated sparge water (168–170 °F) to the mash tun. For a 5-gallon batch, this is typically 3.5–4.5 gallons depending on your boil-off rate and grain absorption.
  3. Stir gently for 1–2 minutes.
  4. Let it settle for 10 minutes.
  5. Vorlauf again (1–2 quarts), then drain into your boil kettle.

You should now have approximately 6.5–7 gallons of wort in your kettle (accounting for a 60-minute boil-off of about 1–1.5 gallons).

Step 7: The Boil

Bring the wort to a vigorous, rolling boil. Watch for the hot break — a foam of coagulated proteins that forms in the first 5–10 minutes. It can cause a boil-over if you are not paying attention. Reduce heat briefly or spray with cold water if foam rises to the rim.

Follow your hop schedule:

Step 8: Chill the Wort

After the boil, cool the wort to your yeast’s pitching temperature as fast as possible. For US-05, that is 64–68 °F.

Fast chilling reduces the risk of contamination and promotes a good cold break (protein precipitation that improves beer clarity).

Step 9: Transfer, Aerate, Pitch

Transfer the cooled wort to your sanitized fermenter. Leave the trub (sediment) behind in the kettle. Splash the wort during transfer or shake the fermenter for 2–3 minutes to introduce oxygen — yeast need it for healthy reproduction during the lag phase.

Sprinkle the dry yeast on top, or rehydrate per the manufacturer’s instructions. Seal the fermenter with an airlock.

Step 10: Fermentation

Place the fermenter in a location where the temperature stays in the 64–68 °F range. You should see airlock activity within 12–24 hours. Primary fermentation typically takes 7–14 days for an American pale ale.

Take a gravity reading at day 10 and again at day 14. If the readings are stable, fermentation is complete.

Common First-Batch Mistakes

1. Not Measuring Strike Water Temperature Accurately

A cheap kitchen thermometer can be off by 5–10 degrees. Invest in a calibrated digital thermometer. An inaccurate mash temperature means poor conversion.

2. Crushing Grain Too Fine

Flour-like crush leads to a stuck sparge. You will stand there for 45 minutes watching nothing drain. Aim for cracked husks with starchy endosperm exposed — not powder.

3. Forgetting to Account for Dead Space

Every mash tun has dead space below the false bottom or pickup tube. That volume of water never reaches your kettle. Measure it and add it to your water calculations.

4. Sparging with Water That Is Too Hot

Sparge water above 175 °F extracts tannins from grain husks, producing astringent flavors. Keep sparge water at 168–170 °F.

5. Boil-Over Panic

The hot break is coming. Watch for it. Have a spray bottle of cold water ready. Do not walk away from the kettle during the first 10 minutes of the boil.

6. Expecting Extract-Level Efficiency

Your first all-grain batch will likely hit 60–70 % brewhouse efficiency. That is fine. Extract brewers effectively work at 100 % efficiency because the manufacturer has already done the conversion. Adjust your grain bill upward if your gravity is low — this is a normal learning curve.

7. Skipping Sanitation Post-Boil

Everything that touches wort after the boil must be sanitized. This rule does not change just because you are now an all-grain brewer. If anything, you have more equipment to sanitize.

Efficiency: Setting Realistic Expectations

Brewhouse efficiency measures how much of the available sugar in your grain ends up in the fermenter. The theoretical maximum extract from 2-row malt is about 37 points per pound per gallon (PPG).

For 10 lb of 2-row in 5 gallons:

Theoretical OG = (10 × 37) / 5 = 74 points → 1.074

At 70 % efficiency:

Actual OG = 1.074 × 0.70 = 1.052

That is exactly in our target range. If you hit 1.048, you are at about 65 % — perfectly acceptable for a first attempt. Track your efficiency over multiple batches. It will improve as you refine your process.

Troubleshooting Quick Reference

Problem Likely Cause Fix
Low OG Low efficiency, too much sparge water Reduce sparge volume, crush finer (slightly), extend mash
Stuck sparge Too-fine crush, no rice hulls Add rice hulls (0.5 lb), stir grain bed, reset
Astringent flavor Sparge water too hot or pH > 6.0 Monitor sparge temp and pH
Cloudy wort Poor vorlauf, fast sparge Vorlauf longer, drain slower
Off-flavors (DMS) Insufficient boil vigor, lid on during boil Full rolling boil, lid off, minimum 60 min
