Production identity
Category: batched cocktail · Style: Batch production · Yield: 10 controlled services before ordinary handling loss · Portion: 1/10 of verified batch by measured service portion
Glass / vessel: House-appropriate glassware · Ice: As specified by service method · Garnish: As required by house spec
Formula — 1× target batch
Scaling table
Scaling is arithmetic, not permission to ignore service behavior. Verify the 1× formula first, then make a controlled intermediate batch before a 50× event batch.
Method
- Verify every bottle/juice/syrup against the current house recipe and ingredient condition.
- Measure the complete batch into a sanitized food-safe vessel; add the specified water only if included.
- Mix thoroughly, chill promptly, label and hold under the venue’s approved procedure.
- Before service, make one finished test portion in the service glass and compare it to the single-drink sensory standard.
- Portion with a measured serving tool and do not top up a weakening batch by guesswork.
Working numbers
Measured pre-dilution liquid represented in ounce-based ingredients: 27.5 oz where applicable. Dilution control: Pre-dilution water in this training formula: 5 oz total. Calibrate against the venue’s ice, temperature and service method before locking the spec.
Storage: Keep cold, closed, labeled and segregated under the venue’s approved procedure. Fresh-citrus batches are same-shift quality products unless the venue has a validated alternative procedure. Shelf-life rule: Use the more conservative of the venue’s safety rule and sensory-quality limit. Do not carry a fresh-citrus batch forward merely because it is still cold.
Labeling: Old Fashioned — 10-Serve Pre-Diluted Batch · 10 serves · recipe version · production date/time · discard/review point · preparer.
Critical controls
- Scale from the current single-drink recipe, not memory.
- Use actual bottle ABVs for any batch-strength calculation.
- Homogenize before the first pour and re-mix when separation is possible.
- Taste a finished service portion before opening the batch to guests.
Production verification
Make the formula exactly as written before adjusting it. Record actual packaged or finished yield, starting ingredient temperature where it materially affects the result, and the service portion. Compare the finished sample against the sensory target: Rich, aromatic, spirit-forward. If the formula includes Bourbon or rye whiskey, Rich simple syrup, Aromatic bitters, Cold potable water for controlled pre-dilution, verify that each product is the intended house specification; a substitution can change sugar, acidity, bitterness, aroma, alcohol strength or texture.
Sensory standard
The target is Rich, aromatic, spirit-forward. Evaluate the beverage at its intended serving temperature and dilution. The standard should be descriptive enough that two trained bartenders can compare results and identify which axis—sweetness, acidity, bitterness, alcohol, aroma, body, carbonation, temperature or dilution—is outside the house target.

Whiskey · Spirit-Forward
Old Fashioned is a rich, aromatic, spirit-forward spirit-forward recipe. Use this page as a working specification, then test the exact brands, ice, glass, price, and service conditions before adopting it as a house drink.
Single-serve spec
• 2 oz (60 ml) Bourbon or rye whiskey
• 0.25 oz (7.5 ml) Rich simple syrup
• 2 dash Aromatic bitters
Method
• Fill a rocks glass with the specified ice.
• Add the ingredients in the listed order.
• Stir briefly, garnish, and serve.

How Old Fashioned works in a real bar
Old Fashioned is a rich, aromatic, spirit-forward spirit-forward built around whiskey. This rewrite treats the listed specification as a working service standard: every measure, preparation choice, product, temperature, and finishing step must be tested together before the venue adopts it.
Ingredient functions
• 2 oz Bourbon or rye whiskey supplies the drink’s principal structure and most of its alcoholic weight. Keep the approved bottle and measured pour consistent because proof, oak, smoke, botanical intensity, or raw-material character can change the balance even when the ounce count stays the same.
• 0.25 oz Rich simple syrup is the sweetness control. Its job is not to make the drink simply sweet, but to connect the base, acid, bitterness, and dilution into one finished shape.
• 2 dash Aromatic bitters is a concentrated seasoning control. Keep the dispenser consistent and taste the finished build before increasing it, because small changes can dominate the drink.
Technique and failure points
Old Fashioned is built in the serving vessel, which makes sequence and temperature visible to the guest. Use the approved ice and glass, add measured ingredients in a deliberate order, and reserve carbonated components for the end whenever present.
A built drink should still be integrated. One brief lift or stir is usually more useful than aggressive mixing. Warm mixers, overfilled glassware, and unmeasured free-pouring are the common reasons a simple build tastes inconsistent.
• An unlabeled syrup concentration causes the same ounce measure to produce different sweetness and body.
• Free-pouring into the serving glass makes a simple drink drift quickly during a rush.
• Changing the glass, fill line, or garnish without retesting alters yield and guest perception.

Version control
Do not silently change the working formula. Record the recipe version, date, reason for change, test result and person approving the update. If a brand or product specification changes, rerun the sensory and cost check before treating the substitution as equivalent. A formula is professional only when the team can reproduce the same intended result and explain why a revision was made.
