Grolsch Clone (Grolsch vi)

Post by Cheshire-cheese » Tue Jul 28, 2009 1:48 pm

Brewday tomorrow
Grolsch Clone
Ingredients for 15 litres
3800g Crushed Lager Malt
100g Crushed Crystal Malt
15 ltr Cheshire tap water (untreated :wall )
100g Hallertau hops
Lager yeast (forgotten which one, will check sachet tomorrow)

The Plan#
Get up at the crack of dawn with everything clean and ready to go.
Start filling the boiler with the water and switch on.
When the temperature reaches 45C, stir in the grist.
Keep stiring and raise the temperature to 55C.
Stand for half an hour (or take a seat whilst you leave the mash for half an hour)
Start stiring and raise the temperature to 66C.
Leave for an hour and a half, but come back to stir periodically as you raise the temp back to 66C.
Transfer the mash to a lauter tun and sparge to collect 20 ltr
Remember, the night before, to note on the boiler where 20ltr comes up to and for God's sake this time fit the hop filter before filling the boiler with wort
Start faffing with the yeast.
Boil with the hops for an hour and a half. No late hops but use copper finings 15 mins before the end and fit IC.
Run water through the IC for half an hour or so.
When cool enough, make up to 15ltr if needed and pitch in the yeast starter.
Ferment in the cellar for 5 days and seek opinions on including a diacetyl rest into the method.



#Please Note: The Plan could be subject to change without prior notice, especially if the plan involves an early start.

The yeast is a sachet of Saflager s-23
The pack advises sprinkling into wort. I've normally made a starter when using Ale yeast but a lazy obedient part of me is saying: follow the instructions.
Then again a disembodied voice of Obeer-Wan is saying "look..." (he too is from Cheshire and look sounds like Luke) "look... use the faff."

The Faff is weak in this one

On a serious note: I understand that it is no longer necessary with modern lager malt but last time I brewed a lager I used this process and the flavour was spot-on. It may well be the same without this method but that will be a repeat brew as a comparison for another day. In other words: Blah-blah-blah not listening etc :D

This has to be my earliest brew to date.
Water almost at 45C now. About to add 4kg of lager malt and 106g crystal malt to 16 liquor.

Nightmare! Boiler wasn't raising the temp above 55C so I had to Transfer to two big saucepans (thank God I'm in a commercial kitchen.)
Hope the boiler isn't knackered already. Maybe the mash was too thick for the 1.8kW element?

Well, I put just water in it and it's now not far off boiling, so it is only any use as a HLT or a boiler. To be fair Brupaks does state that it is only suitable for a thin mash, but to be less fair, it is a bit pants.

Strangely not, or at least takes far too long. Working fine on the boil now. Collected 20 litres with a gravity of 1.054. Target volume and gravity: 16 litres @ 1.068 after the boil

That's the funny thing. The thermostat light went on but there was no noise of heating liquid, nor was the temperature rising, in fact it was falling slightly. I wonder if there's a safety stat on the element.

No harm done anyway. It's functioning well as a copper and we're about 5 mins away from the end of the boil. Next time I'll use my insulated mash tun at a single temperature, there's probably little need for a stepped mash, wouldn't you agree? :mrgreen:

There is a dry filter switch inside that needs bypassing.

I have a Severin Boiler (a grey plated heater element in the base that is visible on the inside of the boiler). I think the Brupaks is a rebadged Severin. Mine kept knocking off the first time I used it to boil the wort but worked ok with water. I managed to disconnect the dry plate warning and it works fine now. There are two switches on these - one for the thermostat and one for the dry-plate - so be sure to disconnect the right one. It isn't that difficult to do and takes just a minute or so.

If you are unsure, shall I post a pic of mine?

It sounds very similar, but a photo would be useful, thanks.

It's a shame I forgot my camera, because it's looking lovely in the boiler, it's cooled to 45C so far and the liquid is a crystal clear rich brown with cloudy clumps of trub massing together.

Before I forget, it was a Protafloc tablet added to the boil in the last 10 minutes, and many thanks to Northern Brewer for sending those :) very kind.

Here is my Severin (I think Brupaks take these and rebadge them). Mine has been insulated:

Take the underside off (mine has 3 of those star screw jobs) and carefully slide out the base - take care as the thermostat dial will be sli onto a plastic spindle - so slide out in the direction of the thermostat.

Here's what it looks like inside. You can see that I disconnected the wire that went via the dry plate cut-off (right-hand side) by simply connecting all the wires to one side of it:

Here's a closer view:

I used mine several times without an issue afterwards although I admit to only using it as a HLT these days. the 1.8kw element drove me nuts in how long it took, and the fact that it struggled to hit a rolling boil without lots of insulation. I now use a converted FV with 2 Asda Kettle elements - much quicker.
