Cold steeped for 24 hours in a mason jar.
Far more subtle flavour than my 175F attempt, very floral aroma and taste, with less of a metallic aftertaste than that version. I also tasted a very mild hint of fruit, more so than in the hot version.
The colour in the mason jar was a a pale straw colour (hint for the people taking this into work in a glass jar – try not to, unless you want urine sample gags for the rest of the day).
