Gravity had dropped to 1.014 by 26th Apr and had been flat for a day or so suggesting fermentation has finished. In line with Cellarmaker tutorial of dry hopping once fermentation is complete, and in line with the article in the same course about Dry Hopping cold, I am going to drop the temperature to 3-4 degrees over 24h starting today (26th April) and then begin dry hopping in a double dose from Sunday 27th April. I will also do a Yeast dump before and after cold crash before dry hopping.
As per Yakima Chief video (https://www.youtube.com/watch?v=nzBcGZ1sWOQ&t=9s) I will spit the dry hop batch of 72g in two, dry hopping on Sunday with 36g Mosaic without a muslin bag, so that 24h after I can drop the hops from the funnel, and then dry hop with the other 36g on Monday 28th April.
After dry hopping, I will clarify with gelatin, and add this (details to be added) to begin to further clarify the beer.
I will then taste and once target aroma and flavour is right, dump the hops and remaining yeast every 24h until bottle day.
In theory, this should produce a highly aromatic, flavour forward, bitter, clear West Coast Pale Ale.
Tried gelatin following SOP v1 but very little effect. Checked other websites and the Binoferm 30% is ready to use. Dosed at 5ml in 20L and left for a further 18h but still a haze to the beer.
Bottle yield as follows:
500ml - 18
330ml - 18 (of which 6 white capped are competition beers)
