This was my post in the 'What Kit Beer Are You Drinking Tonight?' thread from 1 January 2021.
'Drinking the last bottle of my Brewferm Christmas beer, bottled 31.12.17.
I think this kit is probably best between 9 and 15 months but it has certainly changed over time. Starts as a sweet fruit cake taste. At 15 to 18 months, it developed some nice liquorice undertones. Last new year, it had lost the liquorice but had some sherry flavours. Now it has lost that but tastes like a nice barleywine.
When I brew this again, I might put some in a demijohn with some wine barrel chunks for 6 months before bottling as an experiment. '
I deliberately bottled some in 3 large 750ml Leffe bottles so that I could try one at Christmas time 2018, 2019 and 2020 to see how it changes. I think I prefer it after it has been bottled for between 9 and 15/18 months but others may think differently depending on which flavours you prefer.
