I am thinking I might just take the risk here to be honest. I might recork and just leave it. Chance are they will all be drunk soon enough anyway. I have been doing a lot of 1 gallon "experiments" - currently working on a lot of differing organic cordials. I plan on making bigger batches soon then i'll probably take more care over this stuff.
With experimental stuff it's hard not to drink it I guess :-) . FYI anyone in the UK/Ireland Belvoir Fruit Farms (
www.belvoirfruitfarms.co.uk) does a Summerberry Cordial that makes an excellent Rosé without too much hassle!
