Hi,
Recent AG batch has somewhat low attenuation, looking for any advice
style - best bitter/esb
yeast white labs irish ale 004 with starter 1 liter
grain bill does contain just under 10% torrified wheat (does that matter? I assume it ferments out just fine, but first time I have used wheat)
og 1048 (beersmith estimated 1049)
mash at 153-154 85 min (was to be 60, had a conflict )
mash ph ~5.55 room temp, within range as far as I can tell
oxygenate with air pump 15 min
FV is in a lizard-tank heating pad inside a carboy insulator, dig. therm set for 66 , .e.g at 66 it heats up to 67ish (this is one jumper one, the bottom one off if i recall correctly). over the course of this ferm. i saw temps of 65-67 handle. is 65 too low? First time I had used the reptile pad/carboy insulator, it seems to keep the range within a 2-degree handle, i have DIF set to 1 on the dig. therm.(can I set it to zero?)
day one og 1048, had visible krausen in 24 hours or less.
72 hours 1026
5 days 1020
7 days 1017
tried to rouse yeast on day 8
day 9, 1016.5~ it fell just marginally.
unlike most other british-type yeasts I have done, the gravity samples of this seem sweet from 1026 till now.
I assume I have an issue at one or more steps in my process or recipe.
Any suggestions on what to look at or consider doing, both with respect to this batch and in the future, would be gladly appreciated.
