Batch 44Porch Light, 14 June

Observation, 1 highlight, 1 note, 431 words

Brewed from Recipes, 1, with the crystal cut to 8 oz after batch 42.

Batch 44
Grain bill9 lb (4.1 kg) two-row, 1 lb (454 g) Munich, 8 oz (227 g) crystal 40
HopsMagnum 0.5 oz (14 g) at 60 min; Cascade 1 oz (28 g) at 10; Centennial 1 oz (28 g) at flameout; Cascade 2 oz (57 g) dry hop, day 4
YeastAmerican ale, one packet, rehydrated, pitched at 66°F (19°C)
Original gravity1.051, 14 June
Fermentation64°F (18°C) to day 5, then 68°F (20°C), probe taped to the fermenter
Final gravity1.011 on 25 June and again on 27 June
Attenuation78% apparent, about 5.3% ABV
Bottled28 June, 51 bottles, primed for 2.4 volumes

Tasting, two weeks (12 July). Clear, pale gold. Grapefruit and pine on the nose. Cleaner finish than 42 and 43, no butter. A touch thin.

Tasting, six weeks (9 August). Hop aroma fading, as expected. Still clean. Next time, 4 oz (113 g) more Munich for body.

The recipe book as the club reads it: five house beers, no notes or highlights, and the recipe still in development left out.

Recipes — the beers worth brewing again

Shared from a library on know. 5 sections.

Five house beers from a garage in Dayton, written for 5.5 gallons (21 L) at 72% efficiency. Scale them for your system.

Brewed by and for adults. Each recipe lists what it contains, including wheat, lactose and the gluten in barley.

Sections

  1. Porch Light — American pale ale (Observation, high importance)
  2. Low Road — brown porter (Observation, high importance)

  5. Sunday Wheat — American wheat (Observation, low importance)

How it works

Your notebook is good on brew day and poor on every day after. Keep every batch instead: the grain bill as weighed, the gravity charted from pitching to final, your tasting notes at two weeks and six. Then ask your assistant to line up what changed between the good batch and the rest, and share the recipes that won.

  1. Hand your assistant the notebooks

    Give it your recipe sheets and photos of the brew-day pages. Ask for Recipes, a section per beer, and Batches, a section per brew with a table of what happened.

  2. Chart each fermentation

    When a batch reaches final gravity, give your assistant the morning readings and ask for a line chart element under its table, with the dry hop and the temperature rise marked.

  3. Taste twice and compare

    Write your tasting notes at two weeks and six. Then ask your assistant to compare batches of the same beer, citing batch numbers, and flag where two things changed at once.

  4. Share the recipe book

    Press Share on Recipes and leave the recipe still in development out. Batches stays private: it is where the failures live, and the club only needs what worked.

Your assistant, connected to know.sh (Claude, ChatGPT or a local model):

Using know.sh, read Batches on my Garage brewery shelf and compare every batch of Porch Light. Put each batch’s gravities, apparent attenuation, pitch and fermentation temperatures and days to final gravity in a table, in a new section called ‘Porch Light, batches compared’. Then list each difference in ingredients or process and the tasting notes that followed, citing batch numbers. Do not change the batch sections.

Your assistant, connected to know.sh (Claude, ChatGPT or a local model):

Here are the morning gravity readings for batch 45: [paste]. Using know.sh, add a line chart element under the table in its section in Batches: days from pitching along the bottom, specific gravity up the side, a marker on every reading, and notes at the dry hop and the temperature rise. Copy each reading exactly, and leave a gap for any day I missed.
