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! 21 Beer Brewing Software Brad Smith, PhD 22 Recipe Design ◦ Build a recipe by picking ingredients from a set of several hundred preloaded hops, grains, yeasts, etc… ◦ Calculates OG, Color, etc… in real time so you can focus on designing the beer ◦ Print Step-by-step instructions for your recipe Recipe Manipulation ◦ Scale a recipe, adjust bitterness, adjust color, convert from all grain to extract, change to your equipment Recipe Management ◦ Organize recipes in folders, share them in several formats, record data as you brew 23 PC Version Macintosh Version iPhone, iPad, and Android 24 Name, Equipment Ingredients Style Comparison Color Choose Ingredients Custom Fields Mash, Fermentation Profiles 25 Current design is compared against the style guide as you build the recipe ◦ OG, Bitterness, Color and ABV displayed ◦ Lets you focus on the design of the beer itself 26 Screen clipping taken: 5/16/2013, 3:59 PM Brew Sheet ◦ Step by step instructions for any recipe Brew Day Timer ◦ Mash and boil timers in desktop and mobile versions 27 BeerSmithRecipes.com Cloud Recipe Sharing/Storage Web – Share/Search Desktop – Cloud Folder Mobile – Cloud Folder 28 Features Brewday Timer (Mash and Boil) Local (offline) recipe editing Cloud folder recipe editing Editable ingredients Equipment, Mash, Fermentation and Carbonation profiles editable ◦ BJCP Style Guide ◦ Tools: Hydrometer, Infusion, Attenuation, Mash Adjust, Refractometer, Carbonation ◦ Unit Converters ◦ ◦ ◦ ◦ ◦ 29 Resources ◦ ◦ BJCP.org – BJCP style guide Books: Designing Great Beers - Daniels Radical Brewing – Randy Mosher How to Brew – John Palmer Brewing Classic Styles – Zainasheff and Palmer Brew Like a Monk – Stan Hieronymous India Pale Ale – Mitch Steele BeerSmith References ◦ ◦ ◦ BeerSmith.com BeerSmithRecipes.com Newsletter, blog, podcast BeerSmith.com/blog Questions? 30
