Day Patterns

FUERST WIACEK Version 1.1 | What an actual production day looks like


This page documents what actually happens on each weekday in the brewery, in roughly the order tasks are checked off. Patterns shift depending on staff, demand, and tank availability — these are the typical baselines.

Each task links to the responsible SOP where one exists. Tasks marked SOP gap don't yet have one — see todo.md for the running list.

Samples below are extracted from week 9 / 2026 (23–27 Feb 2026), with an alternative Monday comparison from 13 April 2026.


Weekly Brew Rhythm

The typical production week is 6 brews → 6 separate batches → 6 fermentation tanks filled. Each brew goes into its own tank.

Sometimes the mix is different — for example 3 single brews + 1 double brew (paired A + B into the same tank) = 5 brews into 4 tanks. The schedule depends on demand, recipe size, and tank availability.

The 6-singles week is the highest-workload pattern.

Day Brews (typical) Pattern
Mon 0 Packaging day (Up-con T2). Up to ~5 cans + 5 kegs.
Tue 1 Single brew (V2 — day mash-in ~10 AM)
Wed 2 One night brew (V1 mash-in ~4 AM) + one day brew (V2 ~10 AM)
Thu 2 Same — night + day
Fri 1 Single brew (V1 — night mash-in ~4 AM) + end-of-week CIPs

Single vs paired (A / B) brews

When two brews go into the same tank, they're labeled XXX A and XXX B:

  • A is the first brew of the pair (afternoon).
  • B is the second brew of the pair (mashed in automatically the next morning at ~4 AM after A).

This is the double brew scenario — the same tank receives both worts, doubling the batch volume to 36–48 hl.

When the brew is single, no A/B suffix is used, or only A appears with no following B. Each single brew gets its own tank.

Tank filled count varies week to week

Week shape Brews Tanks filled Workload
6 singles 6 6 High (typical)
4 singles + 1 double 6 5 Slightly lower CIP / harvest load
3 singles + 1 double 5 4 Lower
2 doubles + 2 singles 6 4 CIP-light, big batches

Sample week (week 9 / 2026 — observed)

This week looks like a mix — three batches with A + B pairings (649, 650, 651), so 6 brews into 3 tanks.

Day Brews Tank
Tue 24 649 A FV 17 (CIP'd same morning after Mon packaging)
Wed 25 649 B + 650 A 649 B → FV 17; 650 A → FV 18 (CIP started Tue, finished Wed)
Thu 26 650 B + 651 A 650 B → FV 18; 651 A → FV 1 (CIP'd Wed evening)
Fri 27 651 B 651 B → FV 1

Tanks filled this week: 3 (FV 17, FV 18, FV 1). FV 7, 13, 19 are mid-fermentation/conditioning. FV 3, 5, 6, 15 are in carbonation/conditioning awaiting next packaging.

In a 6-singles week the same brew slots above would each fill a separate tank (6 tanks instead of 3).


Monday — Packaging Day

Anchored by CIP Tank 2 (canning line + cellar). Multiple cans + kegs in one shift. End-of-day cleanup. No brewing.

Morning — startup

# Task SOP
1 Start Steam Steam Generator — Weekly Manual Start
2 Dump Water Steam Steam Generator — Monday Hotwell Dump & Condensate Flush
3 Dump Condensate Empty the condensate fridge bucket into the drain — no SOP
4 Flush Shower Weekly Recurring Tasks — Safety Shower & Eyewash — run for ~10 s to flush stale water
5 Up Con T2 CIP Up-Concentration — Tank 2
6 Check CO₂ on tanks scheduled for packaging today Haffmans
7 CIP Canning Line Canning Line CIP
8 ATP swab after CIP (referenced in Tank CIP / no formal canning ATP SOP)
9 Steri Canning Line Canning Line CIP — sanitisation
10 CIP Kegger Kegger Line CIP

Mid-day — packaging runs

Cans run first, then kegs. Cans require a full tank for stable canning-line pressure and head-space management — emptying a tank with cans first risks fill-level drift and DO pickup at the bottom of the tank. Kegs handle the residual better.

Order Task SOP
1 Can FV X (one or more tanks) Canning Line Operation
2 Keg FV X (typically the same tanks, residual after cans) KeyKeg Filling

Volume varies week to week. Sample weeks observed: 5 cans + 5 kegs (Feb 23) vs 3 cans + 3 kegs (Apr 13).

Mon 13 Apr 2026 — alternative Monday (planned, all open)

Planned (24): Start Steam · Up Con T2 · Check CO² FV 1, 2, 17 · CIP Canning Line · ATP · Steri Canning Line · CIP Kegger · Can FV 1, 2, 17 · Keg FV 1, 2, 17 · CIP Canning Line EOD · Flush Shower · Dump Water Steam · Dump Condensate · Prep Chemical Baths · Check Bottles FG · Spund FV 3, 13 · Drop Trub FV 10 · Check FVs · VDK FV 3, 13 · Dump Cone FV 5, 6.

Comparison vs Mon 23 Feb: Same shape — startup steam dumps and shower flush, Up-con T2, full canning + kegger CIP+Sani sequence, packaging runs, chemical baths mid-day, spund, cone dumps, EOD CIP + daily monitoring. Volume varies (3 cans + 3 kegs vs 5+5). The Monday template is robust.


Cross-Day Carryover

Tasks that didn't get done on the day they appeared and rolled to the next:

From Carried to Why
Mon 23 — Drop Trub FV 19 Tue 24 — completed by LE Packaging-heavy Monday; no time to dump cone
Mon 23 — Plato / Check FVs / Check Bottles FG Tue 24 — done early morning Same

Daily monitoring tasks ride forward when packaging fills the day.


Staffing

There is no permanent operator-initial convention — initials in the sample logs above were just present that week. A formal accountability system (e.g. Todoist or similar) may be introduced later. Until then, treat the initials in the historical samples as week-specific.

The week 9 / 2026 sample suggests 2–3 operators on brew days plus the brewmaster, with 1–2 operators handling cellar / lab / packaging in parallel.
