what is the difference between..

i want to do a chocolate stout but what makes the difference between a chocolate stout and a double chocolate stout?i really like the young's double.. im thinking of this recipe.

6 2/3lb dark malt extract
2lb dark dme
1lb crystal malt 60L
1/2lb roasted barley
1/2lb black patent
1.5oz cascade
.5oz hallertauer
6oz semisweet baking chocolate
and so-5 for a yeast

like to add some lactose not shure how much?
how does this sound i know there is a tones or other recipes out there!

I think the double part comes in if you flavor with more chocolate in the secondary... could be wrong though

Double traditionally implies that it's a bigger beer, but young's isn't that big.

Double chocolate stout isn't a style at all, it's just what they named their beer.

I've done sweet stouts with 1 lb of lactose, but young's is dryer than they've turned out. There are lots of clone recipes out there, and AHS's is supposedly very close.

It's just what they want to call it. A "double chocolate" would presumably have more chocolate in it (or more chocolate FLAVOR), but there is no such "style".

It can be more chocolate
Or Chocolate malt and chocolate powder
Or could be a bigger beer.

I'm not sure why Young's call it double.
