I have just bought something equivalent from my brew shop. It has two bottles, one Kieselsol, the other Gelatin, which are already in solution. The product is made in England. The instructions say (from memory): add 1 to 2 g of Kieselsol solution per 4.5L wait 30 mins add the same amount of gelatin solution wait 24 to 72 hrs (until sediment settles) then rack The amount to add is the upper amount for cloudy wine (mead), and the lower amount for a clearer wine (mead) It says it also works for beer. HTH James ------------------------------ Subject: White Scum (MLD #1059, #1058) From: "James P" Date: Thu, 04 Dec 2003 08:46:52 +1000 I won't comment on what the white stuff is, but I've had it on two or three meads/wines so far, and it seems to be where I have acidic fruit. It seems more of a film than a scum, and I either spoon it off, or top up the carboy to over-flowing so that it flows off the top (and then have to clean the carboy). A more sanitary way is to rack wiith a gauze "filter" over the end of your racking can to filter the "scum". I can't comment yet on what impact it has on flavour, but my guess is it is minimal. If you bottle-age you mead, then it will leave a residue on the bottle neck, but if you bulk-age, then you can eliminate most (all?) of it before you bottle.

I consider any rate of bubbling faster than none "good" for primary - and I generally rack to secondary when the bubble rate drops to once or twice per minute (every 30 to 60 seconds). IMHO, YMMV. **************** Avraham haRofeh of Sudentur (mka Randy Goldberg MD) Random Tag: I'm from the government.

YMMV but I always rack to secondary based on the foam head on the must (Kraussen or some such technical term IIRC). This is assuming you are doing primary in a bucket. If you are doing it in a glass carboy under an airlock, then racking at day 30 or so will be just fine. ------------------------------ Subject: Fw: Mead Lover's Digest #1059, 3 December 2003 From: "john doerter" Date: Thu, 4 Dec 2003 11:39:32 -0600 > Speaking of buckets, my primary was in one of those 'ale pails' ... > 6 or 7 gallon bucket with an air seal and a bubbler sticking out of a > little rubber ring in the top.

There is some truth to this. Also note that oxegen in the primary is a good thing to promote rapid yeast propogation. A third item of interest is that you can get a nice foam head on top of your mead.. The air space allows the foam to dissipate without entering the airlock. This last is why I bucket primary my melomels (fruit meads) and cysers. I don't airlock my primary, I use clear plastic shower caps to keep stuff/bugs out of bucket, and rack to glass carboys with airlocks after foam stops. > > > > of Wyeast Sweet Mead (liquid) yeast.

I have heard little dispute of this from people who like it.

Can you explain to me the > chemistry/physics behind doing it this way? No not really.... but here is what i can explain. the early mead has a tendancy for foam in the initial stages... personally I think this has to do with some sort of balance between the sugar and the water and the Alchohol. Anyway while ABV is low and the SG is high the bubbles join to form larger bubbles and have a 1/2 life on top of the bucket slow enough to be several inches high. Kind of like foam on a sink with Joy or Dawn in the water to wash the dishes. This foam is fed from the bottom by the CO2 released by the yeast. (just as the sink foam is fed by air forced under the sink water). I can't say for sure if the foam is a direct function of SG or is related to other factors.... what I can say is if you shake a bottle of water, you don't get foam. You also don't get this foam in Alchohol if you shake it. Nor will any mixture of only Alchohol and water form it. THERFORE it is related to the OTHER THINGS in the must. More rapid Fermentation = more CO2 bubbles = More Foam More Alchohol = Lower SG = Shorter bubble life = less foam Anyway foam is on a bell curve timewise in a must. At a certain point the must no longer supports foam. IME Foam is gone below SG of 1.050 (though I haven't tried to measure to find upper limits.) I'm sure a scientific explanation would be covered in surface tensions of Various solutions. My explanation is ... IMO If you have a foam cap you have a very active fermentation with plenty of food to keep going. ------------------------------ Subject: Re:Bubbles From: "Matt Maples" Date: Thu, 4 Dec 2003 10:40:31 -0800 The bubble rate is not really a good indicator of much of anything. You can't even assume that if it is bubbling it is still fermenting, it may just be de-gassing. There are just WAY too many variables as to why your mead is bubbling at the rate it is. From the amount of water in the airlock, to temperature, atmospheric pressure, current CO2 saturation and on and on and on. Different yeast will have different fermentation profiles, from fast violent starters like your 1118 to slower more steady ferments like ale yeasts (Wyeast Sweet). It doesn't mean one is better than another or that there is a bubble rate you should be trying to achieve. What you should be doing is to try and hit the temperature range intended for that specific yeast strain. There is no way around it, your just going to have to take readings.

But apparently NOT impossible, as many folks are able to ship mead to the IMF or to shows. Can we get some specifics posted as to which companies will accept shipments of mead, wine or beer between persons (as opposed to between corporations)? I'm sure that Ray Daniels, for one, is a fount of knowledge in this area. Want to be able to ship domestic US as well as internationally.
