I just counted my wines in progress and have:

2 6-gallon carboys
6 5-gallon carboys
5 3-gallon carboys
1 2.5-gallon carboy
11 4-liter jugs
9 1-gallon jugs
2 3-liter jugs
1 .5-gallon jug

for 37 batches totalling about 79 gallons in progress. Too many to
list contents. Of these, about half are adaptations of other recipes,
a quarter are "new" recipes, and a quarter are old standards. I'm
drinking a vanilla bean mead as I write....
