That might come in a bit dark for the Dog... your brew should be around 21 SRM according to ProMash... New Castle is a bit lighter in color than that IMO (anyone have the SRM of Newkie???) It should still be quite a tasty brew though... and will be a brown for sure... let us know how it turns out!
If ya do this one again, maybe switch out the chocolate with .5 lb of Brown malt...
Hmmm... now I want to brew another brown LOL
let's see... maybe something like this:
mikey's 3rd Time's a Charm Northern Brown Ale
5 lbs Munton's Extra Light DME
1 lb Brown Malt (~70 SRM)
.5 lbs Special B
.5 lbs Aromatic malt
.5 lbs Biscuit malt
1 lb Pale 2-Row
.5 oz EKG at 60, 30, 15 and 2 minutes
looks like it's time to place an order
whadda ya think???
