Hey you lot. Just starting out with my new Brewhaus 8 gallon pot still and decided to start with Odin's CFW (and my own twist, Ryvita). Recipe;
1 x 750g packet Kellogs corn flakes.
1 x standard packet Ryvita.
3.5kg dextrose.
Cook till gelled.
Add 2 x 4g packs alpha amylase at 70 deg C for conversion. Leave overnight. Conversion of starches confirmed with iodine tests.
Oxygenate and into fermenters with dextrose at approx 26 deg C ambient. Add filtered water adjusted to 4.5 pH with citric (lemon juice).
40g EC1118 (Lowans for first batch) pre-mixed into lukewarm water, pre-tested and adjusted to 4.5 pH. Added to ferment.
Left fermenters open for 12 hrs, then sealed.
This is the result;
Seeing fermentation action but only micro bubbles all way through the process. There is movement in the mash, you can see action. No bubbling from the airlock bubbler at all. OG of this last batch was 1.080. Previous batches ranged from;
First batch (Lowans) - OG 1.052 / FG (10 days total) 1.002. Potential ABV 6.45%.
Second batch (EC1118) - OG 1.070 / FG (10 days total) 1.014. Potential ABV 7.22%. Used 20% backset.
Third batch (EC1118) - OG 1.080 / 14th day of ferment (today) SG 1.028. Current potential ABV 6.7%. Used 20% backset.
These seem like fairly poor figures ?
Fast distillation of the first two batches gave around 50% ABV.
Looking for a few pointers if I am doing something wrong with the fermenting process ?
