Irish moss

Here's one Google doesn't seem to know ANYTHING about.

Irish moss (I think) is seaweed. On the beach you can pick up loads of seaweed.

So which one is it and how I prepare it for brewing?

Here is a starter for more research on the actual method of manufacture.

Carragheen is the common name the latin name is chondrus crispus. It can be found on west coast beaches in England. Not sure about how to prepare it but I think it is just dried.

Bonjour,

Come on, Google knows everything :)

'Chondrus Crispus' seems to be what you're after! Wikipedia elaborates here.

The original collection was from storm tossed seaweed, driven onto the shore by strong winds. Local farmers picked it up from beaches and shores and sometimes waded into the surf with horse-drawn scoops to capture unattached moss. Fishermen took their boats offshore with hand rakes and scrapped the moss from the flat rock shelf where it grew. In the 1970s, large lobster boats equipped with drag rakes and winches were introduced; the steel rakes - about 1 m wide, 25 kg, with about 40 teeth - are dragged across the moss beds.

Irish Moss harvesting has returned to being a part-time fishery, where there is a place for operators equipped with small boats, outboard motors and hand rakes.

Chondrus crispus in France grows mainly around Brittany. However, there are no flat beds, as found in Canada, so the use of dredgers is not possible, only manual gathering. Harvesting is a part-time operation by about 3 000 people, although this number and the harvest are both falling as the living standards of the harvesters rise.

To maintain the value of the crop, careful post-harvest treatment is necessary. It must be kept away from sand and dirt, so drying racks or mats are used (Figure 41). In some areas, the entire line is removed from the sea and hung over a tall "fence" to allow drying, the seaweed being untied after it has dried. In most areas, sun drying for about 2-3 days is sufficient to reduce the moisture content to the required 35 percent level. With practice, farmers can estimate the moisture level by feeling the seaweed, by its firmness and how it bends. If the moisture is above 40 percent the seaweed may rot during storage and transport; below 35 percent the seaweed becomes too firm and bouncy and it is difficult to compress it into bales. During drying, white salt-like crystals appear on the outside of the seaweed; any that are loose and can be shaken off are removed. Buyers do not like damp seaweed, nor foreign matter such as sand, dirt, stones, coral pieces or excessive salt.

Wish you well with that one Mashy! Thought you reckoned milling your own malt was a bit of unnecessary hassle though! :lol:

Yes indeed and still do.
Not sure you can compare that to lobbing a bit of free seaweed over a fence.... :D

With Google, I really struggled to get past brewing supplies or some Jamaican drink.

What ends up in the next brew could be exciting.

Thanks guys.

Off to the beach...

Wow!

Then you may as well try fining the finished beer with an egg too - I'll let you google it ;-)

I use egg white to clear my wine.

So can't see why not.

PS. Sought kelp (see what I did there), only found seaweed - now soaking.

BRILLIANT.

I have to confess I was having trouble identifying this. My first batch was clearly the wrong one.

I have got it right now - your illustration matches my second gathering. Thanks - really.

And although it doesn't come out well, this is red (ish)
