Right now I use a bucket primary and 5 gal secondary if dry hopping or flavoring and am thinking about getting rid of the buckets. Question is if I am only going to use a primary should I use a 5 or 6.5 gallon carboy? 5 gal would clearly need a blow off tube which I understand can blow out some if the hop bitterness

Also with a 6.5 gallon carboy and an extended fermentation could I have any oxidation or infection risk from a large headspace. I understand CO2 drive it out generally but also that better bottles breathe which is where I am leaning.

Go with 6.5 - the CO2 given off by the yeast is more than enough to fill that space. I've currently got 4 gallons in a 7 gallon carboy, and 3 hrs after I pitched, the airlock was bubbling merrily away

So basically do people use a 5 or 6.5 gallon better bottle for about 4 week fermentations?

I just got my first Better Bottle and love it. I will only use glass for long aging.

I use plastic buckets. I can't see any problems unless you're aging 6 months or more

For a 5 gallon batch you will want 6 gallons or bigger. A 5 gallon fermenter would blow off almost every time!

I suggest the 6 gallon Better Bottle or buckets. They are much lighter and way safer!

The best ones are the ultra rare Italian 4.5 gallon carboys. They use special Romanian virgin tears in their glass which imparts a superstitious quality to the taste of beer---AWESOME. But difficult if not impossible to find them.
