Ok, for those who are interested I was able to do a comparative tasting of my two beers.
Grain Bill for both as follows: (due to miscommunication with my regular supplier I ended up with a super weird mix all in one bag, hence using it up on experiments)
0.2 kg 2-row
0.2 kg Munich
0.2 kg Dark Munich
0.2 kg Red-X
0.1 kg Medium Crystal
0.02 kg Torrefied Wheat
0.02 kg Flaked Barley
0.02 kg Brown Malt
0.02 kg Cherrywood Smoked
0.98 kg total for 4.5 L batch (1-gallon)
Target OG - 11 Brix (1.044)
Yeast: S-33
Beer 1: Normal BIaB and boil method
Method
60 min boil
Summer hops 6 g (5.3% AA) @ First Wort
and 6 g 10 mins remaining boil
OG - 11 Brix (same as target)
FG - 3.87 Brix (adjusted)
ABV - 3.86 %
Tasting Notes
Appearance: Very Cloudy Brown. Tan head which stuck around for a while. Lacing down glass.
Aroma: Melon Fruitiness.
Taste: Hop fruit flavour and just enough bitterness (could probably use more). Muddled maltiness. A hint of butteriness perhaps (could be DMS or something weird from the malt mix)?
Mouthfeel: Fairly Full. Carbonation sizzle on first taste.
Beer 2: BIaB and NO-boil.
Method
60 min mash with mash out to 75 C and then held for ten minutes.
6 g Summer (5.3% AA) at Mash in
6 g Summer at beginning of mash out heating.
OG - 12.25 Brix (1.049) (higher than target, unplanned higher efficiency)
FG - 2.92 Brix (Adjusted) (went lower than expected and than the other beer even though OG was higher)
ABV - 5.08 %
Tasting Notes
Appearance: Cloudy Brown with a hint of red. Big Tan head which faded quickly. No lacing on glass.
Aroma: Mostly malty with a little melon fruit.
Taste: Malt forward. Only a hint of bitterness and hop flavour. Another flavour I can't quite pick really dominates everything, as I go down the glass it's more obviously buttery so I assume DMS (no other experience of it). Higher alcohol content not perceived just that strong butteriness.
Mouthfeel: Very full, even thick. Well carbonated.
Anyway, that's my impression of the two beers. I've previously had one of the no-boil beers with dinner and thought it was ok, so I must have just lucked out and combined it with a dish where I didn't notice the DMS, I'll have to wait and see if it ages out at all. The glass I poured tonight, well, let's just say that I finished the boiled one.
