Scheldebrouwerij Klonen?

[sinkas]

Hello, I am an Australian hobby brewer , sorry I have little Dutch ability.
I enjoy the Scheldebrouwerij and Ij beers from your country, particularly the Schelde Oesterstout.
Does anyone have any clone recipes for the schelde beers?

Cheers,

Sinkas

[Hopmans]

Hi Sinkas,

It seems that the beer is filtered whith oyster shells for a slight salty sea flavor.
The ABV is 8,5%.
Not to bitter, and very dark.
Its no longer in production anymore. 

I can't find a clone recipe either.
 

[sinkas]

Thanks for the reply Hopmans:
I have cultured yeast for a bottle of Strandgaper,

this is my Oesterstoutclone recipe so far: Using the info on the bottle, and best guesses

I will filter the wort over shells prior to the boil

Bestaat de Scheldebrouwerij eigenlijk nog wel?

Groet, SiriS

[Oscar]

Volgens de website nog wel.

[Drents Hopbier]

Volgens de website nog wel.

Nu wel in België:

Laten wij ons dan voorlopig richten op het vinden van een kloonrecept van brouwsels van de Scheldebrouwerij. Ik heb overigens dit bier nooit gezien/geproefd. Gefilterd door zeeschelpen, schreef iemand?

Overigens, ik weet niet hoe de brouwerijen in Nederland/België over 't algemeen zijn, maar kun je niet gewoon vragen welk recept ze gebruiken? Zo heb ik van meerdere Noorse brouwerijen de rechtstreekse recepten gekregen van o.a. Nøgne Ø, Haandbryggeriet, etc... Niet geschoten is altijd mis

[JWVG]

Als het niet meer in productie is, is het misschien makkelijker om het recept op te vragen. Kent iemand de (ex-)brouwer?

[BuBS]

De brouwers van de Scheldebrouwerij komen ook op hobbybrouwen.
Dus wie weet?
Ze werken met Wyeast gist en welke gist gebruik je voor een stout... Guinness.

Gr BuBs

[BuBS]

Vanmorgen een van de brouwers gesproken en gewezen op deze draad.
Dus misschien geven ze wel antwoord.
Sinkas had ook al gemaild naar de Schelde, maar ze hadden nog geen antwoord gegeven.

Juicht Kaboodle toe, Zo, sprak u aan de brouwers Schelde? En zij vermeldden ik hen met de elektronische post had verstuurd? Grote vooruitgang! Case

[JWVG]

Hi Sinkas (Case?),

You can relax now - in this new section you can post in English. I'm not sure to what extend you followed our discussion, but the moderators decided that this will be a special section in which only non-Dutch speakers can start a thread. In order to keep the Dutch character of the forum, the rules are still pretty strict: this section is only meant for non-Dutch speakers who want to inquire on Belgian/Dutch beers and how to brew them. This is because it does not make much sense to redirect people with questions like that to english-language fora like 'Northern Brewer'. It is the only section in which English messages are allowed.

Since you are doing exactly what this section is meant for, I'm pretty sure you can do it in English (I'm paraphrasing what I've heard - I'm not a moderator, but this is my understanding. If a moderator wants to correct or corroborate - please do so).

Now, let's see if you make more sense in English than after an automatic translation into Dutch  .

Cheers, JW.

[Oscar]

Grote vooruitgang! Case

Aha dus eigenlijk heet je gewoon Kees. 

[Edgar]

JW summed it up nicely. You can be somewhat proud that on account of your request, a revolutionary change has taken place on the forum

[Menno]

a revolutionary change has taken place on the forum

Edgar, you should mean: a BIG revolutionairy change...

[Jacques]

The change is not so big. English is ony allowed on this particular board.

On the other boards Dutch must be written in a correct manner.

[sinkas]

Hi all,
 I will write in English, since my Dutch translation is a little rough.

My name is an Anglo-ization of Kees, don't know why, but that's the truth.

So we live in hope the Schelde brouwers will respond,

I particualry want to find out what they do with the bloody oster shells!

Cheers.

[JWVG]

I particualry want to find out what they do with the bloody oster shells!

Me too: if they use it in the filterbed of the mash, my guess would be that the pH of the wort would be seriously affected as some of the calcium carbonate would dissolve. Also, of course, the Ca concentration of the wort would increase. There might also be an effect on micronutrients. And maybe some 'ocean flavours' of other organic compounds still in the shells.

Or it was just a marketing thing rather than a brewing thing, of course.

Hi Sinkas, guess what....I have a bottle of Oesterstout in front of me. 

This afternoon, I purchased this bottle at a beer festival. The bottle has a final shelf life of june 2009 indicating that it is rather fresh.

The label mentions the following ingredients (in order of ascending weight % added): water, munich malt, caramalt 120, roast malt 900, Challenger hops, Goldings hops and yeast. The latter you already have, only a matter of propagating it....Looking at your recipe proposal you would need to have higher amount of Goldings compared to Challenger hops.

The bottle further mentions it is filtered over Oyster shells. I guess the (milled) shells are not mixed through the mash. One reason to add it to mash is that it might lead to better filtering properties in case there would be a lot of oat or wheat malt present but is doesn't appear so from the ingredient declaration on the bottle.

Because this beer is from Zeeland, a province in the Netherlands closely associated with the sea, I guess the use of the Oyster shells is more emotional then functional.

I guess the shells mainly consist of silicates and some sea water ions. The silicates might take over part of the filtering functions normally used by Kieselguhr etc. On the other hand the beer is bottle-conditioned so it is not extensively filtered.

Hi William,

shells actually consist of lime (CaCO₃), not silicates. Silicates are geogenic, not biogenic. So I think my remark about a possible pH effect, as well as an increase in Ca²⁺ ions (and possible some trace ions) is still valid. As a soil scientist working in the Netherlands, I work a lot with soils from reclaimed land. All of those soils that contain shell fragments have a high pH. It's difficult to predict whether the relatively short mash filtering period would also lead to such a pH increase, but it's certainly a possibility.

If you want to filter with silicates, use sand  .

[sinkas]

For some reason, I was thinking like a hop-back full of oyset shells, that had been boiled to sanitise, that was the wort soaks over them for a few minutes, picks up a little flavour, then on to the kettle.

In terms of the yeast, my attempts to culture from the oesterstout have failed, but I was able to culture from one of thier other beers, "Strandgaper",  Problem is, one of the previous posts, suggested that they use Wyeast Guinness strain for this beer.. (This post seems to have dissappeared)

I have a Leffe Blond type beer fermenting with the cutured Strandgaper yeast, will see how it turns out..

Cheers

Ah, that makes sense. Good to have an expert here.   Do you happen to know the solubility of calciumcarbonate at say pH 5,4? Besides an increase pH, an increase in calcium ion activity also might improve amylase activity although adding calcium in another form might be more effective.

[JWVG]

I'm not a chemistry expert, but I would say that the solubility is not the issue, as all dissolved carbonate ions would react with the protons to form CO₂ and H₂O. Rather, the issue is the solubility rate. And that's of course dependent on the average grain size of the shells. Lime powder would dissolve much faster than a whole oyster shell  . And, of course, time is limited since your filtering time is limited. Difficult to speculate futher than that.... Asking the brewers would still be the best approach.

Hang on, isn't lime usually CaO? I would say CaCo3 (or Calcium Carbonate of course) is called chalk, no?

BTW I would personally forget this whole oystershell idea. Anything fishy I think would have to be avoided in beer and if it's just the chalk/pH effect, you could simply add some chalk. My 2 cents.

[JWVG]

Hi Edgar,

sorry, that's my background. In agriculture, liming means to add calcium carbonate. But you're right - in the 'normal' world 'Chalk' would be the better term. I also agree that you would need very, very good reasons to bother with actual shells....
