Tasting Notes (2)

Notes:

Appearance: pours a cloudy, rust-hued orange gold. Nice head formation that stands for a while a slowly dissipates. Head whips back up with a swirl of the glass. Not a fan of the color. Aroma: a little pleasant phenolic spice. Almost like spiced pear. Apricot. Preserved lemon. Taste: Orange, peach, apricot (must be the Omega DIPA), apple cider, clove, cinnamon, vanilla. A little of those LAB fermentation notes hanging around in the corners. Will be interesting to see if they clean up.

Notes:

Mouthfeel: Round and juicy with slight, soft oat creaminess. A little rough around the edges in a way that seems a little dirty. Will be interesting to see if the yeast cleans this up or if it persists in the weeks ahead. Drinkability and notes: surprisingly drinkable for a beer with no bells and whistles, but definitely not quite what I’m aiming for. There’s something borderline astringent on the finish that I’d like to clean up. Hard to tell if it’s tannins from over-extracted husk or something chemical. Worth researching. Changes for next time: the points of interest in this beer are getting a cleaner LAB fermentation and examining what may have caused the rough finish. Careful not to over-sparge perhaps. Maybe its the equipment? I want this beer on it’s own to be softer, lighter, fluffier and creamier.
