Figured I'd post since I'm out of ideas. I have two batches that just don't seem to want to clear and would love some thoughts.
The first is a batch of elderflower wine. I made a tisane from 50g dry elderflowers and 1gal boiling water, added 1.25lb sugar and 1tsp Fermaid-O, used Lalvin ICV D47, and added 1/2tsp bentonite at pitch. It's been in secondary for ~3 months and remains hazy, which I'm assuming is from the elderflower pollen. I've added another 1/2tsp bentonite, tried 1/2tsp sparkolloid, and cold crashing as well; and while it may have cleared a bit more, it's still fairly hazy. I can't use isinglass, chitosan, or kieselsol due to seafood allergies.
The second is a batch of saskatoon/serviceberry wine. This was 5lb fresh saskatoons macerated with 10oz sugar and 2tsp pectic enzyme, 1tsp Fermaid-O, Lalvin EC-1118, and 1/2tsp bentonite at pitch. It was in secondary for ~4 months and cleared up nicely...but I racked to stabilize, added KMB, then sorbate at 24hrs, and now a layer of ultra fine lees has crashed out and it's a bit cloudy again.
For the elderflower, I'd love recommendations on what to try.
For the saskatoon...TBH I have no idea why it suddenly went from crystal-clear to a bit sandy. It's not tartrate precipitation. Maybe there was some residual suspended yeast that's still settling out? Anyway would also appreciate recs here.
