Notes

BREWGR NOTES

Rate: 2/10

ABV: 5.4%
Yeast: Mangrove Jack's Cali Lager M54
Attenuation: 77-82%
My attenuation: 68%
Yeast aroma: Neutral
Recommended IBU: 25 – 45
IBU achieved: 36
Ferment: 18-20ºC

Recipe: N/A
Achieved: OG: 1059 FG: 1018 ABV: 5.4%

Notes:
– Using Vienna this time
– Added 100g Rice Hulls. 150g Torrified
– Trying Mangrove Jacks M54 a lager yeast that has the ability to ferment at ale temperatures without the associated off flavours. Extended lagering periods are also not required.
– 5kg grain takes 4C off mash water temp.

Do again: No. WAY TOO SOUR. Don’t know why. Yeast?
