I'm rather like Tom in that I have 32 5-gallon carboys, and 5 6-gallon carboys (1 in plastic). I also have a 50L neutral barrel, which is soon to be paired with another brand new barrel next month.
Keep in mind that I bulk age. Normally, the youngest I bottle has already been racked 4 times and has sat a year. I don't normally degas, file, or filter. Hence why I have so many carboys. I only have perhaps an average of 300 bottles filled at any one time that are continuously recycled. So in the end, nearly everything I drink has spent minimum 1 year in bulk, and about 1 year in bottle - even the whites.
