About This Beer
Sixth captured Red IPA and the major recipe pivot of the line. Moves from the long-running HBW-Gladfield template (multi-crystal stack + Aurora + small Shepherds Delight) to a simpler new structure. Companion to RIPA 2 Under Pressure — same recipe, different fermentation approach. The pair is an A/B test of pressure vs non-pressure fermentation on the new template.
The Red IPA Pivot
| Red IPA line (Gen 5 / #26 / #32) | RIPA 1 (Feb 2024) | |
|---|---|---|
| Base malt | Gladfield Ale Malt 4.6 kg | Gladfield American Ale Malt 5.0 kg |
| Crystal stack | Aurora 1.2 + Lt/Med/Dk Crystal | (none — replaced) |
| Colour malt | (multi-crystal) | Gladfield Redback 0.55 kg |
| Shepherds Delight | 0.06–0.10 kg | 0.45 kg (significant bump) |
| Munich | (none) | 0.70 kg |
| Wheat | (none) | Eclipse Wheat 0.05 kg |
| Hop pair | Pacific Jade + Mosaic (250 g) | Citra + Superdelic (300 g) |
| Yeast | M44 US West Coast | BRY-97 American Ale |
Crystal complexity replaced by a single Redback colour malt. Shepherds Delight bumped 4–5× to become the largest specialty. Hop pair entirely new. Yeast back to BRY-97 (last used in batch 15, the 9.5/10 Red IPA from September 2021).
