okies, preliminary results on spices in rosehip wine are in, cos i just racked it.
1/ is about 2 weeks since the spices were added
2/ Mace, a slightly more than subtle flavour of mace, very yummy, and i would definately repeat it.
3/ Cinnamon, can't taste this at all, but with a mouthful rather than a sip i might do. opinion is on hold.
4/ Star anise, wonderful! really added something without being overpowering. Good for wintery nights i reckon, or just something unusual to show off
other observations;
the mace was very mobile in the wine, sinking, collecting bubbles, rising. i didn't see it happening but sometimes the mace flower was on the top and sometimes not. Star Anise mostly stayed on top tho at the start of racking i couldnt see it so it must have sunk. by the time i was half way through it was on top again. The cinnamon sank after a couple or 3 days and stayed at the bottom. The mobility of the spices probably had something to do with how much flavour has been transferred. Maybe smaller pieces of cinnamon would have worked better, or grinding it. Mace and star anise, i wouldn't change the method, doesn't need it.
there's a haze in all 3 demijohns. none any better than another. Only time will tell if it will clear or be one of those pectin hazes that will only go so far unless i intervene in some way. Experience tells me they will probably appear clear in the bottle even if there is a haze when viewed in a demijohn. but hey i may get lucky and get beautiful clear wine.
i can't tell whether the woody nature of the spices has added any dryness (didn't bother with a control).
