Conditioning at approx 14° without blowoff. Sample Somewhat aggressive dark malt flavours, overly thin. Malt and overall flavour profile would benefit from toffee / biscuit. Some sour taste, probably from yeast in suspension. Hops flavours need a little additional freshness - lemon or citrus would also help bring out the orange/marmelade notes. Overall orange-cocoa flavour of the wort has dropped out significantly.
12/8/2021 10:30 PM over 2 years ago	+3	Sample				12/8/2021 10:30 PM over 2 years ago	Head: At present nicely carbonated, slightly low of perfect but good head formation and retention. Colour: Pretty dark for a porter. Definitely need to review SRM prediction for this one - could go a lot lighter and that would probably improve on taste imperfections too. Mouthfeel: noticeably thicker, contributing a lot to the overall balance, which is much improved. Didn't take SG, possibly its the priming sugar. Aroma: Very pleasant, fresh aroma. Can smell yeast. Hops like fresh grass and herbs, with a good amount of spice. Overall very inviting.! Taste: Taste much fuller and better balanced than before. Hop flavour of marmelade or bitter orange is predominant and quite possibly too strong - actually maybe that explains the sourness? There is a very noticeable sour-burnt aftertaste halfway through the beer, which is definitely too unpleasant for many palates. The sourness has a strong cherry taste which shines through after the initial marmelade/bitter orange. The flavour hops and roasted malts should both be reined in by a good 20 - 50%, and I think we might have a winner. Lets also see what happens with a longer conditioning - that's a promising note! I still think a bit of biscuit would help, as might a touch of caramel. Both should be pretty restrained, caramel may or may not work. Maybe a bit of ruby-type malt would work instead of both? And/or something from the Empire Ale/Monroe/Barba Rossa mix? A rounder cherry note could work really well, even together with the biscuit and caramel. If it doesn't blur too much together. Overall I find this a very promising direction for a modern porter, albeit needing taming! The cherry chocolate marmelade combo actually works, and there is a promising hint of biscuit, caramel, or peanutbutter- and honey sandwich, that needs to be pushed up a notch or 2 in volume for this beer to balance out. The existing flavour profile probably needs to be wound back a little, but a really intense porter might be possible by leaving it as is. Lets see what further conditioning does!
