Anyone experience with OLD Arabier from De Dolle Brouwers?

A friend -not a beer geek- has offered me an old 75cL bottle of Arabier (bottled ’89, ’90 or ’91 - those are the years on the label but none is chipped). Don’t really know what the flavours will be (well, I don’t expect a lot of hop character anymore or if it will even be good.

Anyone experience with this beer? Would it still be good, or just nice and queer? Want to offer something in return, and don’t expect to open it very soon.
