A spectrum of choices…
Deliberate - Mechanical
Artistic

Come up with an idea
Research the target style and beer


What are you trying to accomplish?
◦ Style, Clone, Unique beer?

What does each ingredient contribute?
◦ Can I do it with fewer ingredients?
◦ Is the beer balanced?

How do the techniques contribute?
◦ Do they support overall goal?

What’s Unique about my beer?
◦ Read Radical Brewing
5

Start with the BJCP style guide (BJCP.org)

Books

Research Online (styles and recipes)

First Hand Research
◦ Provides target OG, color, bitterness, some ingredients and
history
◦ Designing Great Beers, Brewing Classic Styles, recipe and
style specific books
◦ Google search, BeerSmithRecipes.com, discussion forums,
blogs, style specific articles
◦ Sample commercial and home brewed beer!
6

What ingredients define the style?

What alternatives might I consider?

How does each contribute to my goal?
◦ A Wit requires unmalted wheat
◦ Weizen banana/clove flavors come from yeast
◦ Dry Irish Stout needs roast barley
◦ Vary the yeast, grains, hops used
◦ What about something really new (aka Radical Brewing)
◦ Can I simplify (SMaSH style) rather than dumping everything
but the kitchen sink in?
◦ What can I get rid of?
7

Use Software or a spreadsheet
◦ Match your equipment

Estimate





Original Gravity
Color
Bitterness
ABV (rough)
Compare these to your target style
8

I like to work in percentages
◦ Base grains first (80% typical)
◦ “Key” specialty grains next (5-10%)
◦ Remaining grains (body, ABV, etc) (5-10%)

Select grains that match your target
◦ Ex: Maris Otter for flavorful English Ale

Understand what each brings to the table
◦ SMaSH brewing (and variants) a great way to
understand what each grain does
9

Bittering Additions

Aroma Additions

Dry Hopping
◦ Tend to use a single addition, long boil to achieve my
target bitterness (IBU) level
◦ I use Bitterness Ratio (IBU:GU ratio) for balance
◦ Most of the aromatic “hop oils” will boil off within a few
minutes
◦ I’ve moved towards very late or steeped/whirlpool hops
to maximize aroma and hop oil flavor
◦ Shorter contact times (24-72 hours)
10

Select yeast for effect

A Starter is Important for Liquid Yeast

Fermentation Temperature Matters!
◦ “Styles” for yeast provide a good starting point
◦ Go “off style” to achieve a specific effect such as a dry
finish, low attenuation, or complexity added by esters
◦ A typical liquid pack is 100 Bil cells when produced and
degrades about 20%/month
◦ Ideal pitch rate for 5 gal, 1.048 ale: 164 Bil cells
◦ Lagers ideal pitch rate is double that of ale
11

Know your local water source!

Consider the Mash pH when designing beer

Water additions
◦ What is your Residual Alkalinity (How to Brew)?
◦ Is your water deficient minerals or is it too hard?
◦ Dark grains lower pH – less of a worry
◦ Light beers - need buffer or acid to lower pH
◦ pH buffers or acids – to manage mash pH
◦ Overall water profile considerations
 Should I target a particular profile for this beer?
 Do I need to start with bottled water then add minerals?
12

Pick mash temp as needed for beer body:

A Single Infusion Mash - 98% of the time!

Consider Brew-in-a-bag

Prevent Stuck Sparges
◦ Light body – 148 F
◦ Medium body – 152 F
◦ Full body – 156 F
◦ Add melanoidin malt to simulate decoction
◦ Use flaked or torrified grains when you need to work with
unmalted barley/wheats/oats (no cereal rest)
◦ Saves an hour due to short sparge and cleanup
◦ Use rice hulls for wheats, oats, etc…
13

Late Extract Additions

Segregate Dark Grains into Tea

Add Honey/Fruit (some sugars) after boil
or in secondary
◦ Reduces scorching, increases hop utilization
◦ Steep dark/harsh grains separate from mash
(Gordon Strong)
◦ Reduces perceived bitterness/harshness
◦ Fragile fruit/honey aromas boil off
◦ Risk of infection relatively low after primary
fermentation complete
14

First Wort Hopping

Mash Hopping

Late Hop Additions

Steep/Whirlpool/Hop Back Additions

Dry Hopping – use pellets just before bottling
◦ Add hops to pot during sparge (smooth flavor)
◦ Don’t bother!
◦ Very late may be best!
◦ Great for preserving volatile hop oils
◦ Adds small amount of bitterness
◦ Trend to shorter contact times – usually 1-3 days
◦ Recent research indicates 24 hours may be enough
15

Pitch two different yeasts
◦ Either together, or separated in time

Add Lacto or Brett in Secondary
◦ Sour beers only

Diaceytl Rest - Lagers
◦ Raise temp by a few degrees for a day in secondary

Cold Crashing
◦ Crash beer to near freezing in secondary
◦ Lager or Ale – may require more yeast for bottling
16


Is Clarity Important?
Ways to improve clarity
◦
◦
◦
◦
◦
Watch protein content of grains
Cool wort quickly – Chiller
Use Irish Moss/Whirlfloc at end of boil
Choose yeast with high flocculation
Add a fining agent:
 Isinglass, Chillguard, Gelatin, Polyclar
◦ Cold store beer after carbonation
17

Must be able to Judge your beer!
◦
◦
◦
◦
Evaluate external appearance first
Capture aroma up front – right after its poured
Evaluate color, clarity, head retention
Taste the beer- overall impression first
 Finish, malt, hops, aroma
 Obvious flaws
◦ Mouthfeel
◦ Overall Impression

The BJCP score sheet is a great guide

Beer Judges are some of the best brewers!
◦ Provides 17 taste terms (grassy, phenolic, astringent, etc…) used for
evaluating beer
18

Diacetyl/Butterscotch

Astringency/Grainy

Phenolics/Medicinal

Dimethyl Sulfide (DMS)/Cabbage/Eggs

Sour/Acidic flavors
◦ Use starter, diacetyl rest for lagers
◦ Oversparging, sparging too hot, excess tannins
◦ Chlorine in water, bacteria, oversparging
◦ Bacteria, high moisture malt, covering during boil or
insufficient boil
◦ Sanitation, Bacteria, excessive acid
19

Pro brewers perfect their beer

Seriously evaluate the flaws in your beer

Brew it Again!
◦ Many homebrewers never brew the same twice!
◦
◦
◦
◦
Adjust grain percentages?
Change hop schedule or varieties?
Fix or try new techniques?
Correct specific flaws?
20

Start with a clear artistic vision
Do your homework (research!)
Create a list of potential ingredients’

Run the numbers

Consider which techniques are best




◦ Simplify whenever possible – more is not better!
◦ Grain bill first
◦ Then hops, yeast, misc items
◦ Mash, Boil, Fermentation and Aging techniques
◦ Body, Clarity, Eliminating flaws
Judge your beer after brewing
Correct flaws and iterate!
