Racked the port last night into 3x Gallon jugs as I need the carboy free to start another port kit. Took a sampling. My expectations were low to begin with so while I am pleased with the results so far, I am not overwhelmed. Looks are dark crimson and thick (viscous), nose is rich with heavy body, loads of red berries, strong alcohol, and unfortunately strong KT. Taste is actually OK, well balanced, quite hot at this stage... but with a lot of KT/"Cheap wine" flavours.
Have not added any further of the reserved concentrate as I feel this will only exacerbate the KT/Cheap kit taste. Going to keep ageing it for 6-12 months. Will check in again in a few months with another taste. As I have it now split into 3 gallon jugs I may experiment with various sweetening liquids to try and cover up the KT... Suggestions as always are welcome!
