Decided mid brew session a couple of weeks ago to make a small beer with the second runnings and some DME I had left over, so I ran to MLHBS while the wort just chilled out. Grabbed a dry yeast I'd never tried before (Mangrove Jack's M44) and pitched it straight to the wort, no starter, no rehydration. Took foooorrreveeer to show signs of fermentation, then ran hot for 3 days. Kegged it after a week of primary and a week of secondary (with dry hops), but there is some off flavor that I just can't identify. It's not astringent, I no-sparge and only drew off about 4 gallons of seconds, so I am assuming its a fusel alcohol. Any chance this is going to mellow, or do I now have a keg full of third (or fourth) beer?
