Super F

[Eric]

There appears no category I can find for finings, so please move this if there is. I've chosen dispensing as nearest option to cover this topic.

Has anyone used Super F and if so, what might be your opinion of it in practice?

Isinglass is wonderful, except for homebrewers for its short shelf life in liquid form or the pain of getting it into liquid from solid matter. Super F appears to have a substantially greater shelf life, and while it isn't in the same league as isinglass and its primary purpose may be to produce vegan friendly cask beer, 48 hours clear down time sounds great, provided some friendly supplier found it practical and profitable to repackage Super F in suitable volumes.

I'd first want to know exactly what it was. Loose claims that it's not on what is an ever evolving list of harmful chemicals is exactly that. That flags up, for me. A mysterious claim to make. It could be charged plastic, or other synthetic, nano particles with a higher environmental cost than organic fish collagen like isinglass. I respect the wishes of vegans, but would really prefer to know more about the chemical nature of the claimed 'alternative'. I'd say opt for a yeast strain that clears sufficiently by itself.

Separately, isinglass doesn't need to be a PITA to prep. It's possible to prep enough for a single batch. I use Magicol, which, like any dried form, stores for years dry. The 'secret' is to dissolve it in cold water over a day or two in the fridge. It's a cold-water fish collagen. Be patient and leave it alone for that day or two to dissolve on its own. Just give it a good shake before pouring in the cask then rolling the sealed cask up and down the floor a few times. Trying to prep too much too soon using the 'stick blender' method is wasteful and less effective.

Well I'm pleased to read that somebody finds Magicol isn't a pain to make, although I do know your water supply is very soft and nothing like mine.

As for plastic, yes it probably is, but that doesn't stop me using brewbrite, which does a better job when mixed 50/50 with Protoflac than Protoflac does by itself.

As for a faster flocculating yeast, you obviously don't know the yeast I use require rousing about a dozen times during my usual 2 to 3 day fermentation. I have no problems with that when my casks remain in place, just when a garden party is arranged and the beer needs to be put in place and tapped a day or so prior to the event.

Thanks.

Being a silica based fining, I wonder if this is the homebrew equivalent:

Could be, could be. Hadn't seen that, just Murphy's technical notes that drew my attention. Maybe Rob will drop in and tell us.

Mind you, my thoughts were of larger volumes, enough for a year's worth of brews, taking advantage of its shelf life and hopefully more cost effective.

[nallum]

Rob's YouTube team will only provide the sales spiel, I'm afraid. Like how to prep isinglass the wrong way and how enzyme-based cleaners are 'safe because they're natural'. Concentrated enzymes can be anything but safe, frankly. Don't snort the stuff, Malt Miller fanboys.

[Eric]

I think I'll ask the same question on another forum. Sorry Rob, this wasn't what I'd hoped for.

[nallum]

Sorry, Eric. No offence to you intended. I just couldn’t care less about what salespeople think generally. The cost of greed crisis is only going to support the unraveling of society. They’ve all become increasingly full of it, as far as I can tell. To the extent quality of products and services is no longer driving sales.

Thanks Craig, I've ordered 3 from the Malt Miller and will do a test.

I'm not one who takes offence, so don't think you've offended me, I'm too old to dwell on such matters. You might have offended the Malt Miller and his team.

Give yourself a break and look for the bright side. Cheers.

[nallum]

Agreed, but I won't ever be promoting the MM. My integrity is worth a lot more than a cheap 10% discount on a private forum. It is what it is. That's a fact. And I can defend my stance any day of the week, because it goes against my principles. Something too many lack these days, apparently. Funny how it's 'my problem'. Even though I'm not selling anything. Very funny. I offer advice to help people, not help screw them out of money. There is an obvious difference.

I think you will find it is 6%, John.

Rounding this off, a 7ml vial of the BrauSol was added to 23 litres of pale ale that had been casked 6 days after brew day when cooled to 12C. After 2 days it was clear and a day later was bright. Here it is having been stored in my beer store, an addition to the house without any temperature control in use.

The beer was likely at around 4C when drawn and the probe shows a temperature when the picture was taken after the condensation was largely removed.

The Roses Chocolate box contains not chocolates but a Ginger Parkin Cake made to this recipe.

The oatmeal was replaced by Jumbo Oats we couldn't cook, so blitzed to make a fine powder, the SR flour was replaced by plain gluten free plus a heaped spoon of Baking Powder. The treacles were substituted by homemade #4 invert sugar made in excess for my Milds.

Rob did make contact and on his site I found 250ml packs of BrauSol. https://www.themaltmiller.co.uk/product ... ial-250ml/
I believe 3 or 4 ml may be enough for a 40 pint brew. which will be tried next time.

Hey Eric,
Thanks for posting your findings, really helpful for the community.
I bet that Parkin is amazing, specially with a slab of salty butter, cut so think you can see your teeth marks!
