In my experience, the rhizomes spread underground and produce their  
own new shoots without human intervention.  I just pull them up and  
cut off the rhizomes from the main network and replant.  I attempt to  
dig them up before the shoots get too long, but if they are, I don't  
worry about it.  I cut them off if I need to, but the rhizomes  
probably grow better if they have the shoots on them.  My lone hill  
of Nugget produces anywhere from 10 to 20 new shoots every year that  
I dig up and donate to brewers in need at our club meetings.

So I guess I'm saying I'm surprised that anyone would actually have  
to take steps to cause your hops to form new shoots - mine do it on  
their own without any encouragement.

Subject: Frozen Beer

I'd try thawing and re-pitching just to be on the safe side. Some yeast 
cells may have survived the misadventure but may be in rough shape as a 
consequence.

Subject: RE: Plastics and Hot Water

Hi Richard,

A few pieces of information for hot water and plastics.  It's a very
good questions and should be a concern.

For PVC it must be realized that the operating temperature is 140F.  In
some PVC's, chemicals can leach out.  As an example, garden hose
manufacturers at one point made a hose that you could drink out of (yes,
we have all done this many times and it concerned me that they all of a
sudden came out with this version).  However, they pulled this off the
market because in the heat of the sun the water in the hose causes
plasticizers to leach out.  I think the hoses that are approved for
drinking are now made with a different safer liner.

Polypropylene, however, is the preferred plastic for hot water/wort.  It
has a working temperature of 210F with intermittent temperatures even
higher.  The plastic is also listed as non-toxic and listed as FDA
approved.  It is also approved for many chemicals, so wort is not a
concern.  We use Polypro in our HLT's and Mash Tuns and it works great.


So, if your going to use a container, I would recommend the Polypro.  It
can be drilled and tapped easily for temperature probes, valves,
fittings, etc. (we can supply these tanks w/o the Brewmation stuff built
in if you want to make your own mash tuns or whatever...just drop me an
e-mail).

Hope this helps.

Subject: New Hop Rhizomes

Regarding Derric's reply to my post on new hop rhizomes:

An article that mentions it is here:
    http://www.freshops.com/gardening.html
and you are right, it doesn't say.  However, it seems
to me that you would NOT cut them off from the roots.
In nature, the bines would just fall over and it
would spread that way ...


That's what I thought also, however, I wondered why they attempt to
grow new roots if they were already attached to the main rootstock.
