Hi folks,

Was trying to give advice to a neighbour about his fourth brew:
Mangrove Jack's Irish Stout 1.7kg
1kg Dry Dark Malt
100g steeped roast barley
23 Litres

He was saying his OG was 1036 and after two weeks it was 1018, but had fermented a bit cool in that period, down to 16 at times. From Ian's spreadsheet on this site, substituting Cooper's Stout, the FG should be 1010. Mangrove Jack's site, however, suggests even lighter stouts are 1018-1025. That seems pretty high for this recipe.

He's stirred it up and raised the temp to 19, but the FG hasn't shifted.

Anyone have experience with this kit/yeast and what to expect?

Cheers,
B
