Tsuyama Beer Festival

Maki, myself and some local friends of ours adorned our 浴衣 (Yukkata, A traditional summer style Kimono) to attend the local ビ-ル祭り(Beer Festival), to sample some of the local beers from Okayama. I especially like the pink 'sakura' beer we tried, sweet and fruity, but I was surprised you cannot really buy these beers in bars! No one really seems to know why. Japanese people love local produce and the idea of limited or season food or drink seems to appeal to them; then why not the local, seasonal beer? Why do they they produce it if no one drinks it? Or where do they sell it, aside from the festivals?
