Hey all,
Does anyone out there know a recipe for Matilda Bay Red Rooftop Lager?
Just finishing one now and it is a delight. Any help would be muchly appreciated. If not I recommend buying one, or even six.







When I read about the evils of drinking, I gave up reading

Its actually called Rooftop Red Lager.
I'm so embarrassed...

I thought about making a Rooftop Red clone about a year and a half ago but then didn't when I became convinced I couldn't make good lagers up here without a brew fridge. I put down an oktoberfest brew on the weekend as I thought it might have cooled down enough to make something half decent, but looking at the thermometer on the fermenter I think I am mistaken, oh well. When I came up with the recipe I realized it was identical to what I had planned for a rooftop clone.

The Matilda Bay website is quite good in detail for brewers. It says that Rooftop is either a Vienna style lager or Marzen/Oktoberfest lager - both fairly similar. Made with carared and melanoidin malts, Hersbrucker hops late in the boil and has hints of toffee and caramel. Colour 60 EBC and bitterness 29IBU.

Vienna and Marzen are very similar style, Vienna made with Vienna malt which is darker than pale malt and marzen with Vienna and Munich malt which is darker again and is supposed to have a reddish amber colour.

I mostly do extract brews so here's what I put down

Morgans Blue Mountain Lager
1kg Morgans MB Chocolate Malt
1kg Coopers BE1 (dextrose and maltodextrin)
12g Hallertau Hersbruker steeped in boiling water
Saflager

Probably not going to be 100% true to style. The morgans choc malt is equivalent to 1150g munich and 200g chocolate. Marzens can have small amounts of choc malt but should probably also have some crytsal malts to give the caramel flavour. According to beersmith this is going to have 23.8IBU so you could probably add a hop schedule with the hersbrucker to up the bitterness and is going to be about 23EBC, not nearly as dark as rooftop.

If I like how this turns out I'll probably look at getting some of the carared and melanoid malts. This should get the colour better. I think these are specialty malts so only need steeping rather than mashing. I'm confident I'll be corrected if I'm wrong here. Could also look at some amber extract or caramalt (caramalt is the lightest crystal malt isn't it.)

Hope this helps

Finally, something I can contribute.

Great recipe Earle..which saflager would you recommend ? Putting this one in To Do book.

I'm no expert on yeasts .....yet? I've only just started using better yeast so I used the Fermentis S-23, wasn't much choice at the HBS I went to in Bowen. I'm going to order some others to try from craftbrewer. Maybe someone else has suggestions?

I found a place on the net that sells and delivers grains in what ever quantities. So I bought some Carared and melanoidin grains. Is it true that i should just need to steep these? I also got some vienna grain that i'm going to do a mini mash on to add to the brew.
Is the BLue mountain lager a good coloured lager to start with? I want this beer to be red, not orange.
I was thinking of starting with something blonde?

Carared and Melanoidin grains are specialty grains that only require steeping, whilst Vienna malt is a base malt that requires mashing.
