Sudden vinegar taste

[darksky]

Today i made another consecration clone to replace what's in my barrel which I tasted 2 weeks ago and it was phenomenal. Took sample today and it smelled and tasted like vinegar. What happened in last 2 weeks. plan in fruiting it hoping that will help. 9 months in barrel. Any ideas on what's wrong maybe sampling it did something to it.

If it turned in two weeks, that seems to me like acetobacter. As opposed to oxygen ingress, which eventually allows Brett to metabolize alcohol into acetic acid. Still, it's worth asking, what size of barrel is it? Small barrels will allow more oxygen ingress.
