Grid Blonde v1_5

Summary:
Brewed 12/2/21
same recipe but changed to vienna malt from honey malt. i think i like the honey malt better but not a huge difference. also used CTZ for whirlpool just cause thats what i have. i also think i prefer idaho 7. i accidentily doubled the magnum addition and it is noticeable more bitter. also don’t prefer the higher bitterness. for this go i used london fog which is pretty good for this beer but not my favorite yeast.

Brewing Notes:
12/1/21 Made 1L starter of WLP066 london fog
started didn’t seem to get going as normal
was milky white by 8am next day
but didn’t get foamy till 1pm right before pitching
a reminder to go back to imperial. i just have not had good luck with white labs yeast. this pitch was one month old from my local hb shop. clearly not a health yeast.
12/2/21 normal 3V brewday. did 1oz of magnum rather than 0.5 so a bit more bitter than intended 🙂
12/3/21 ~6sec bubbling at 8am
strong bubbling at noon
12/4/21 steady bubbling
12/7/21~3sec
12/8/21 ~4 sec
12/9/21 ~5 sec
12/11/21 ~9 sec

cold crash to 35F
12/19/21 collected yeast
rack to 2 kegs ~4.5G and 1.5G

nice beer. as noted about – a bit too bitter and london fog flavor profile not my favorite. prefer this beer with chico strain from imperial (flagship) of all the different yeasts i’ve tried. also like it with honey malt.
