Best Bitter recipe

[joe_r_harvie]

I made a bitter a while ago and found it was a bit thin. I upped the 2-row by 0.25kg and increased the boil by 30 minutes and remade it. Results are great. Sweeter, maltier more caramel flavour which is what it wanted but along with that came an alcohol increase and some alcohol phenols I don't want in my next batch. I know decreasing the malt or boil time or both will reduce the phenols but I don't want to lose the sweet aroma and flavour. My mash is high at 154 degrees. If anyone has any suggestions it will save me some more trial and error. I posted the latest recipe (I batch sparge so my grain base is high):

31 Litres non-treated water

Grain Bill
4.75 kg 2-row
0.35 kg Dark Crystal
0.1 kg Wheat

Mash in 31 L at 154° for 1 hour

1 tablet irish moss at 75 minutes

Here is the recipe I have used for years. I love it. If you decide to stick to yours and make a few changes, I would add Biscuit Malt and change the base malt to Marris Otter.

If you want to decrease the phenols, I say ferment at a lower temperature, and also think about getting some new yeast. The fact that you are using 10th generation yeast could mean that there are some mutations. With that malt bill even with the increased 2-row you shouldn't be getting phenols in a best bitter.

[joe_r_harvie]

Thanks, I will decrease temperature and see what happens. I have used yeast over 50 times before... I get used to the slight mutations.

I'm with CC, if you're getting phenolic with that grain bill, dump the yeast.
