# PSB Brewery Layout
_Created: 2026-04-11 — Captured from Topher via stream of consciousness_

---

## Building
- **Dimensions:** 100ft deep × 20ft wide (~2149 sq ft)
- **No loading dock** — all deliveries through front door
- **Courtyard** behind brew house (not ours)

---

## Patron Space (left side, front ~70ft)

- **Front:** cafe seating, 2 wingback chairs + chess table near bar, full glass facade
- **Middle:** library (2 couches, coffee table, bookshelf with periodicals/reference/trading library + board games)
- **Back section:** 3 picnic tables, 2 dartboards, custom MAME arcade machine
- **Back wall:** ring toss game + fire exit

---

## Brew/Production Side (right side + back section)

- **Bisecting wall:** starts at back-left corner, runs ~70ft forward, turns 90° right to form back-of-bar wall. Encloses ~30ft deep back section from patron space.
- **Back wall left to right:** end of patron space → bisecting wall → bathroom 1 (~8ft wide) → moproom (3×12, narrow side facing the 20ft width) → brew house fills remaining width to right wall
- **Front (right side):** bar → cold room → office → brew house

---

## Brew House (right side, back → front)

### Hot Side (back → front)

**Back corner:**
- Stacked IBCs: CLT top / waste water bottom
- Sink
- RO unit (300 gal/day) mounted on wall above/next to CLT — feeds CLT, waste goes to waste tank

**HLT:**
- 7bbl electric
- 4×8kW 3-phase heating elements (208V Y config)
- Normal operation: 3 elements on HLT duty, 4th terminal available to move to RIMS

**Mash Tun:**
- 4bbl total (3.5bbl usable)
- RIMS system with same 8kW heating element (moved from HLT terminal when needed)
- CIP ball system
- PID pump — hard piped to kettle, bidirectional

**Kettle:**
- 4bbl (3.5bbl usable)
- 4 dedicated 6kW 3-phase heating elements (24kW total)
- Hard piped to mash tun with PID pump between
- Can vorlauf, whirlpool, or transfer between vessels
- German decoction capable (send mash to kettle, boil, return to mash tun)

**Flow:** RO → CLT → HLT → mash tun ↔ kettle (bidirectional pump) → whirlpool in kettle → plate chiller → fermenters

### Cold Side (back → front)

**Fermenters:** 2 double-stacks along right wall
- Stack 1: Orange top / Red bottom → TILT reads as **Pink**
- Stack 2: White top / Green bottom → TILT reads as **Black**

**Control panel + dual-stage plate chiller:** between kettle and fermenters

---

## Walk-In (7×10, right wall at front, near office)

- Brewery-facing wall: bakers rack
  - FOH: sodas, NA beers
  - BOH: hops, yeast
- Half barrels + sixtels, hard-piped through wall to 15 shanks behind bar
- Gases stored here: tall CO2 tanks, 75/25 bar gas (for stouts), pure nitrogen (for nitro hard lemonade/hard coffee)

---

## Retail Cooler (right wall, between bar and front door)

- Double-door commercial fridge
- NA beers, charcuterie boards, canned singles, 4-packs

---

## Storage Lofts

**Back loft** (over bathroom/moproom area):
- Spare parts, empty cans

**Front loft** (over cold room/office):
- Glycol chiller
- Chemlab for water profile back-salting (custom regional profiles — Burton, Edinburgh, Pilsen, etc.)

---

## Additional Equipment

- **Industrial shelving:** grain storage between fermenters and office
- **Grain mill:** between shelving and dividing middle wall (rated 2 tons/hr — unverified)
- **CIP cart:** 2×25gal vessels + PID pump, mobile — can service any vessel

---

## Menu

- **Google Slides:** `1Ihya9H7V6u1os88Y0Fc4U_DMbRI3i_ZZTrVlTT9O3-c`
- On-tap: beer flights, slushies
- To-go: NA beers, canned singles, 4-packs, charcuterie
- 15 faucets (actual count TBD)

---

## Suppliers

- **LD Carlson:** primary malt source (ships, 55lb bags standard, also 5/10lb available)
- **MoreBeer Pro:** backup malt source

---

## TILT Hydrometers

- **Green** — HotForTeacher-4-26
- **Pink** — 70megOhm (TILT reads as Pink/Red)
- **Black** — Seltzer Base (TILT reads as Black/White)
- **Orange** — Mount Vernon Molasses (kegged 2026-04-11)

---

## Key Relationships

- TILT colors = physical TILT device names (not foam color)
- TILT → ESP32 bridge → Brewery Home Assistant → Fire Stick display
- Brewery HA: `brewer.taildc9eb.ts.net`
- Display: Samsung Family Hub touchscreen (Pi-based)

---

## To-Do / Verify

- [ ] Re-index Qdrant vectors (brewery collection has 35 points but 0 indexed vectors)
- [ ] Confirm TILT data flowing correctly on new machine
- [ ] Verify 15 faucet count + gas setup details

```
