Any LBV that has been filtered/fined at bottling will not likely improve any with age. Most of them are that. "Traditional" LBV are not, & may improve with age. Not all labels clearly say, but at least the back label should say whether it is "bottled ready to drink & does not require decanting", or "will throw a sediment and requires decanting", or some such thing. Used to be that most "Traditional" LBV were held a few years to age, then released when ready to drink. I think due to market changes, more are being released earlier, but so far Warre's & Smith W. are still aged.
I haven't been impressed with '94 Taylor LBV, nor were most folks on the old forum format when it was released. For some reason, I liked the Fonseca better. Neither is Traditional, so should not improve with age.
I loved '96 Noval LBV (Traditional) early this year, & someone else commented on the '94 being good, but I haven't seen it.
Someone else has mentioned '94 Warre's LBV, but I don't think it has been released yet. I'm waiting...
