I have not tried using s-04 but I would love to know how this affects the outcome. Recently I made this again where I added 4 oz of aromatic malt to help bring out the malt flavor. I also added 2 oz of black patent malt to increase the SRM and it has a stronger amber color. I'll repost the results in 6 weeks.
I am surprised this thread has gone so quiet!
I made a beer that is similar to the original recipe on this thread, but is definitely different - pale malt, carmunich, crystal, (a lot of) biscuit, malenoidon. I mash hopped with some South African hops and late hopped with Amarillo and Chinook.
The end result is very drinkable, although it probably should have been hopped a bit more.
Anyway - the point is I split the batch and used S04 in one fermenter and S05 in the other.
The S04 has come out a bit sweeter and the hop flavour tends to come on quite late and linger around a bit at the end. The S05 version is not particularly dry, but definitely drier and the hop flavour is upfront and doesn't linger (not as much). So the S04 lets you taste the malt before the hops arrive, whereas with the S05 the balance is there all the way.
It is not an in your face kind of difference but I definitely prefer the S05 version. The S04 version is a full 1% ABV lighter than the S05 (which is 7%)....the grain bill was generous.
I tried the same thing with an american brown ale, to which I added honey to try get the OG up. I don't think I boiled it for long enough as both batches ended up at 6.4% - which i thought was strange given that I got such different results with the AAA. With this style I can't really decide which I prefer, although I think the S04 would not be judged well at a BJCP event if entered as an american (or english) brown ale, whereas I think the S05 version would probably do quite well. The difference with this batch is similar as to what i describe above, but I think S04 works better with a darker beer than it does with the amber.
