my cellar is a few cases of bottles
i could only imagine room for 30 barrels
"Barrel envy", something non-winemakers have no clue about.
All jokes aside, storage is a very serious question that all too many winemakers don't think through before doing. After purchasing my first barrel (used, it's neutral) I discussed the situation with a non-winemaker friend. The folks I purchased the first barrel from had a second 54 liter barrel, and I was debating on buying it. His reaction was, "Just buy it, it's not that much money." He was right, the purchase price was not a problem in any way.
I had room for one barrel, but not a second. I solved this by constructing a barrel rack out of 2x4's so they are stacked -- taking up the same floor space. The solution works fine, but once the barrels are full this structure ain't moving. I dropped the inside of a 3 piece airlock behind the rack -- I won't get it back until I rack the barrels this fall. [I have a LOT of airlocks, so it's not a problem, but it illustrates a point.]
He also didn't consider that in purchasing the second barrel, I committed to making 6+ mores cases of wine each year, which requires creating a second batch of at least 16 US gallons to keep that barrel full. When done, I have to store that wine.
The moral of this story is: think things all the way through before increasing production.
