Bottled the plum last week. I am really pleased with it and I'm looking forward to seeing how it develops.
I would say that the flavour pack definitely added taste and body. I am wondering if people f-pack in wines with even a good, strong dose of fruit? I only added an f-pack as I felt the fruit taste and content was far too low/weak after fermentation. But maybe an f-pack is always helpful with fruit wines.
I haven't tried plum yet; apparently I need to..
Flavor packs are only useful until you start getting your feet wet in 'all-fruit'/no water methods; it's kind of hard to 'add more flavor' to something that's already fruit juice lol
But yes, it's possible to f-pack with fruit - and that's basically what you stumbled on in the Mead reddit that you mention below:
Been reading the reddit for Mead and I have noticed many of them recommend adding fruit to the secondary. Is that common? I would have thought you would chuck it in the primary as you would with normal wine to extract maximum flavor and to help feed the yeast.
They do this to avoid the heat build up and yeast activity levels that happen during the beginning stages of fermentation. With some of the red grapes, too hot of a fermentation can lead to 'cooked fruit'-type flavors; the same, in essence, it true for other fruits, in that the fermentation process alters the original flavor of the fruit into something, most times, more complex; like blueberry wine to me comes off very Merlot-ish, doesnt taste very much like popping a fresh blueberry in my mouth.
When you add the fruit later, there's not as many yeast to chew on the tidbits of that fruit, so its more of a fruit-flavor addition than it is a fermentation-sugar/feed the yeast addition..
It's something usually done more often in the meadmakers/mazers circuits, but when 90-95% of the wine you've made all tastes like honey, I'd probably wanna change things up a bit here and there as well.. It's a decent technique though, and has its place in particular applications.
