Valley Brewer Style Session # 2 – 5C Helles Exportbier.
Brew went well, slightly slower mash due to a finer crush. Good volumes and initial gravity with nearly 24L in the fermenter at 1.052.
Mash schedule
Step 1: 63 °C for 45 min (fermentability, crispness)
Step 2: 70 °C for 20 min (malt body, smoothness)
Step 3: Mash out: 76 °C for 10 min
Fermentation very slow and steady at 9C and < 1psi, velocity decreased and gravity started rounding off at about day 10 or 11 at 1.017.

Gravity dropping approx 1-2 points per day.
No fermenter additions and no stirring or mixing, just clean and steady fermentation.
