Someone posted early last week that they had purchased a glass conical.

Can we get more details?

Thanks.

I have made the equivalent of conicals with demijohn's by inverting them in a bucket with a tube going up to the demijohn's bottom to act as a vent. You have to wire the stopper in and the bucket needs a large hole for access. They are fun to watch and a bit scary to handle ( I filled them inverted through the drain). I didn't find any improvement in my beers and the yeast handling was not the advantage that would have made it worthwhile to me. The shoulder slops are plenty steep to slid the yeast to the mouth. I used a 3/4" ball valve for a drain.

I have yet to see a glass vessel with the optimum 60 degree slope of a conical fermenter. Anything else is a poor compromise. The Fermentap system that was sold for a while and used an inverted carboy was found by most people to be a pain in the posterior. Otherwise glass would be an excellent medium because the yeast has difficulty sticking to it, although of course it's also fragile.

Bill check out Italian demijohns. The yeast slides perfectly down its sides when inverted.

The wine demijohns I have seen frighten me in terms of their safety. If you think a glass carboy is dangerous, the glass used in the demijohns is only about half as thick. I couldn't recommend using one.

Inverting those things is really asking for trouble. The glass is the thinnest on the upper portion of the demijohn, which would be the part that is supporting the weight when inverted.

I have used the demijohn method many times including the 14.5 gallon ones. I don't advocate their use for a lot of reasons but it is an option. The use of a bucket as a stand seemed fine.

Frankly I am unimpressed with the whole idea of conicals on a homebrew level anyway. They don't have the head pressure needed to extrude compacted yeast easily. Otherwise I found that I wasted a lot of beer. I will say that the demijohns were a hoot to stare at!

Are you thinking of the V vessel? I've never used one. I was thinking of getting one when their price dipped to $125 but since I don't do 5 gal batches anymore, I would need something bigger like one of the minibrew conicals.

Cheers,

Dan, This really depends on the bottom dump set-up. I have an inch and a half tri-clover fitting with an elbow and a butterfly valve on a 24 gallon conical. No issues draining trub/yeast. I think 1/2" ball valves can work too as long as there are no elbows.

I found that 1/2" ball valves clogged very easily. Even 3/4" that I changed to was a problem. I can easily see that 1 1/2" would not have that problem but I wonder how fast you can stop the flow when the slug ends. 24 gallons is probably fairly high as well. This would help a lot.
