Also, can you put gas onto the Fermentasaurus?   No gas, no "closed" transfer with any setup.

You could still gravity transfer as long as there's a balance line tying the headspaces together.

Equipment and Software / Re: Pump reviews
« on: April 18, 2018, 09:43:55 PM »
I've had a March 809 for about a decade (150 batches) with nary a problem. I take down the head about every two years for a deep cleaning, not that there's ever been anything in there. I'd like to do it a little more frequently but it's a plastic head and a little delicate.

FWIW, last time I looked at homebrew pumps about a year ago, everything that was advertised as a stainless head still used a plastic impeller. Caveat emptor et al.

Going Pro / Re: How many fermenters?
« on: April 16, 2018, 02:45:45 PM »
A couple ways to look at this. There's straightforward math: assuming this is a 1/2 bbl system, brewing 100 bbl/yr, with an average of 14 days in fermenter, you need 100*14/365*0.5 = 7.7 fermenters.

Lots of other considerations though. That's brewing more than once every other day; do you have a full-time brewer? Even if so I'd double- or triple-batch for the cost savings both up-front and in labor - a 1.5 bbl conical doesn't cost three times what the 1/2 bbl does; at those scales it probably isn't even double.

Another way to think about it is from a brewery logistics standpoint. Will you have a brink? If not you'll want to have at least one more fermenter than the number of strains in the cellar, so that you can harvest and brew on the same day without necessarily having to throw a tank CIP on top of it.

Other Fermentables / Re: Is BLC a substitute for BTF?
« on: April 13, 2018, 04:36:00 AM »
No, not at all a substitute. BLC is a caustic cleaner, BTF Iodophor is a sanitizer. Be very careful with the BLC if you do keep it; it's extremely corrosive, especially undiluted.

General Homebrew Discussion / Re: Getting the mash to 170 degrees
« on: April 11, 2018, 07:41:23 PM »
Right. You need to account for heat loss in the mash and heat loss in the boiling infusion for it to be accurate.

I think Denny was pointing out that you also have to account for the heat capacity of your mash tun.

Anybody have experience of big changes in other, maybe ale, strains  between liquid source and dry?

Nottingham comes to mind. The Danstar dry product leaves behind acetaldehyde that I haven't experienced with the Wyeast version.

Homebrew Con 2018 / Re: Homebrewcon 2018 -Who is Going?
« on: March 09, 2018, 07:14:55 PM »
I'll be there at least for the conference and hopefully a few days before/after since I have friends in the area and have never been. Waiting out the spring breakers to see my disposable income and therefore how long a trip I can book.

Questions about the forum? / Re: Homebrew Con

NHC = National Hurricane Center so a bunch of weather geeks show up...nobody wants those guys around :)

If they're anything like the tornado folks they're our kind of party.

Yeast and Fermentation / Re: Pitch rates
« on: March 08, 2018, 04:30:43 PM »
You'd need to define a target (over) pitching rate to be able to say. Assuming 1.2 million/mL-°P and 20 billion cells per gram, it would be ~3.6 grams per gallon.

The wrinkle there (apart from assuming cell density for the dried yeast) is that without a count you won't know viability for the non-rehydrated dry yeast. You could assume 50% loss from pitching dry, but those assumptions really start to compound at some point.

All Grain Brewing / Re: milled grain
« on: February 01, 2018, 04:19:09 PM »
The thing you want to avoid which is LOX is stored in the arcospire of the malt

Obviously it couldn't be liquid oxygen, so what's LOX in this context?

Are hops GMO?

Only in the sense that cats and dogs are GMO. ;D

I'm still not convinced you didn't get some bum hops.

If you're in Ska's distribution footprint, try their Modus Mandarina. That's a 100% MB dry hop, and only about half as much as you're using.

It's definitely not out of the question that you got some improperly packaged hops, especially if your supplier repackages them.

The hose insert you're referring to sounds like it would go into the beer line; these have been around a while, at least in home-made form.

In order to reduce pressure on the gas side, you need a regulator, so for four beers that would mean a splitter/manifold and three more regulators. At the homebrew scale you can compromise and manually adjust the regulator to each pressure (easier to go lowest to highest), topping the kegs off every day and/or after a session... if you can remember.
