There's no cure...there's no answer.
I'm thinking of that stunningly depressing Joe Jackson song this morning as I read that in addition to the increases and shortages of malt, hops, and glass, barrels are in short supply. The Scotch whisky industry is booming, and that means the price of used bourbon barrels has gone up steeply -- and the price of used sherry casks is just nuts. Coopers are running flat-out, although high prices don't always mean high profits. Barrel-aged beers could get even more expensive.
Like I keep telling people about the hops shortage: don't expect it to get better real soon.
