What size and style carboys do you use ?

For a 5 gallon batch?

6 gallon carboys or better bottles work great, as do the "brew buckets" which are around 7 gallons. The 6.5 gallon carboys are also nice, as they have a threaded neck for carboy caps. A 5 gallon carboy is definitely too small for fermenting beer, there just simply isn't enough headspace for the krausen. I prefer the 6.5 gallon glass carboys since there is plenty of room for "extra" beer! If I happen to overshoot my volume on a recipe, no big deal...I just add it all to the carboy. Plenty of headspace for even a fairly violent fermentation.

I've got:
2 - 6g glass
1 - 6.5g glass
1 - 5g glass
2 - 7g buckets

I have :
5 x 6.5 gallon glass carboys
1 x 5 gallon glass carboy
1 x 3 gallon glass carboy

I love my 6.5 gallon glass carboys. So easy to clean (just oxyclean soak) and I know there is no oxygen getting to the beer (Ale Pails are slightly O2 permeable).

But for the price if I need more fermenters someday, I'll probably buy 6 gallon better bottles.

All of the above in glass.

I've got similar to mnadamn:
4 x 6 gallon glass
3 x 5 gallon glass
1 x 3 gallon glass
1 x 12 gallon plastic

Just buckets unless I'm using secondary, and then glass, except I do have a few plastic bottles in case I'm already using the glass ones. But it's rare that I use a secondary.

1 6 gal glass
1 6.5 gal bucket
3 5 gal glass

Picking up a mystery glass carboy this week. Gonna start splitting batches to really get a better grasp on yeast differences and whatnot.

1 5 gal glass
3 6.5 gal buckets

I've been debating on getting a couple 6.5 gal glass for the primary, from what it looks like on here is that it works well. Plus I think it would be an added bonus to see the fermantation taking place. Time for them to be added to the equipment list.

2 buckets
2 6.5 gal glass
1 5 gal glass

I really like the 6.5 glass for primary, and plan on getting a couple more.

One 7 gallon bucket

two 6 gallon BB

0ne 6.5 glass

Eight 4 gallon #1 pete water bottles mostly for Applewein 0r splitting an 11 gallon batch into 3

I wish i could find 6.5 but all i got is a 6 gallon

5 gallon BB here, usually only as the secondary, though I have used them as a primary with a blowoff tube no problem.

3 6.5 gal.glass
5 5 gal. glass
4 3 gal. glass
1 2 gal. glass

None of the above.

90% of the beers I brew are brewed in a plastic bucket. They are in the primary for about 4 weeks then bottled. No carboys.

However I do have 4l, 3gal, 5gal and 6gal carboys. The 4l and 1 of my 5gal carboys are glass the rest are better bottles. These are used for bulk aging high gravity ales, meads and wines.

15 gallon keg for all my batches, both 5 gallon or 10 gallon.

I have gotten into Better Bottles more recently and prefer those.
Two 6 gal Better Bottles
Two 6.5 gal cabroys
Two 5 gal carboys as secondaries

I use four 6.5 gallon glass. Homebrewing wouldn't be homebrewing without an element of danger.

:cross:

1-7 gallon ale pail (plastic)

1-6 gal carboy (glass)

2-5 gal carboys (glass)

1 7g Ale Pail
2 6G BB's
2 5G BB's

I am clumsy as hell, so I'm not allowed to use glass carboys. Did I mention I work with bombs for a living?

2 x 6.5gal Glass Carboy
1 x 5gal Glass Carboy
1 x 5gal Plastic Carboy
1 x 6gal Plastic Carboy
1 x 12gal open fermenter (not really used)

My 6.5gal carboy's are the nice thick ribbed old-school glass. I love them, and hope to get more.
