Hi.

I made three batches (15 gallons each) of dried elderberry /
blackberry / summer fruits wine (some oaked with oak dust/granules,
some with oak cubes and some with oak staves) with a six month
interval between each batch. I have now racked the first batch 4
times (since it entered the primary fermentation container) over the
last 2 years. It has been sitting in better bottles since and is
looking, smelling and tasting quite good.

I now plan to bottle the first batch faily soon (the subsequent two
batches will follow at 6 month intervals). I planned to rack a final
time before bottling and am beginning to consider how much sulfite or
campden tablets (if any) I should add in this last rack - per 5 (UK)
gallon batch. I added some (I think a campden per gallon) at must
stage and I think the same quantity again after about a year but I
confess I have lost the paperwork. (I also have no access to sulfite
tests that I know of).

I invite suggestions of a suitable addition per 5 gallon batch to help
this wine age. The wine is medium heavy with dried elderberries and
other fruit and I plan to age it in bottle at least a further year
before drinking any more - it is still pretty tannic (as an ex-smoker
and tannin lover that is perfect - I like that in a wine), but I would
like the wine to survive at least a further 3 years in bottle after
that - preferably more. I plan to bottle some with high end colmated
cork, some with natural cork and some with synthetic seals as an
experiment unless anyone has definitive arguments for a single high
quality and sourceable seal for my recycled bottles.

Suggestions please and thank you
