Here's my Underground Ale recipe, similar brew to Newcastle:
2oz crystal 55
2oz chocolate malt
1oz black patent malt
6lbs light DME
1/2oz Target 8%AA for 60 minutes
1/2oz EK Goldings 4.75%AA for 15 minutes
Please note, these hop additions are calibrated for a 2.5gallon boil so you may need to adjust if you are using less water.
