I started a fruit bomb mead on Christmas day following the TiSONA protocol with an OG of about 1.092 / 22.01 BRIX
After 72 hours (yesterday) my SG had dropped to 1.060, which is around the 1/3rd sugar break. As we know, this is when the final 4th feeding is due, however being at the 72 hour mark this is when the 3rd feeding was due. I gave the 3rd feeding at 72 hours. Today my SG is down to 1.048 and I've given a 4th final feeding.
Question is, was this correct? Should I have given a double feed at the 72 hour mark? Was I mistaken to give a 4th feed today?
Recipe below
OG: 1.092
BRIX: 22.01
pH: 4.1
Total volume: 15L / 3.96 Gallon
Temperature: 15-18C (FastFerment Jacket + Ice Bottles)
Clear Blossom Honey: 5.4kg
ICV-D47: 10g
Tesco Frozen Edv Mixed Fruits (strawberries, blackberries, raspberries and blackcurrants): 5kg
Potassium Bicarbonate: 1 tbsp - ADDED 12h before fruit and pitch
Pectinase: 1 tbsp - ADDED 12h before fruit and pitch
Rehydration
GoFerm: 12.5g
Water: 250ml
Rehydrate yeast using GoFerm protocol
- Mix 12.5g GoFerm with 250ml water @ 43°C
- Let cool to 40°C
- Add yeast
- Let stand for 20mins
- Add 250ml must
- Let stand for 5mins
- Repeat 2 more times
TiOSNA - Low N * 0.75
Brix x 10 x N requirement factor x batch size (gals) / 100 (ppm) = Total Fermaid-K (grams)
22.01 * 10 * 0.75 * 3.96 / 100 = 6.53697g
1.63g per serving
fruit adjustment = 1.5g per serving (probably could have gone down to 1g, but 1.5 seemed so low anyway)
