Annadel Syrah Ferment Taking Off

After inoculating the must Monday morning, the cap was barely up Tuesday morning – not solid, sort of half-hearted. It was a little firmer at the afternoon punchdown (punch #5). I raised the setpoints at each visit – the lower from 69° to 72° F, and from 72° to 78° F in the afternoon.

Note that I have settled on a span of 3°F for determining the upper setpoint – I will only be reporting the lower setpoint going forward. The must read 24° Brix at both punchdowns.

This morning the cap was solid and the Pod was reporting 20° Brix at 77° F. I dissolved/suspended 8 g Fermaid K (19 g/hL or 1.6#/M – note that the maximum addition rate for this product is 2#/M) and 15 g DAP (0.33 g/L) in about 200 mL warm water and added this at the punch. This is the first of three planned DAP additions. Upped the setpoint to 80° F.

Though I peaked the Pinot fermentation at 92° F my plan for the Syrah is to peak this ferment at 86° F as I did for the two Cabernet lots.
