They say it's bottle conditioned, but I don't believe they recommend any aging. I know with Russian River Brewing IPAs, they absolutely don't recommend bottle aging. Which is ironic because the first IPA was created so that there would still be flavor when transported from the UK to India which would take weeks. Sour beers can be bottle aged. I had an expensive sour that I left in the fridge for three years and it was great after that.
