#28 - Coffin Ship Survivor Imperial Stout [All Grain]

I was really happy with how my previous imperial stout turned out despite its below average marks (31/50) in a recent brewing competition. I am down to my last two bottles so I decided it was time to make a new version to try out a few different things. The new version is going to use different hops, contain alterations to the malt bill and also will have oak chips added after the initial fermentation as ceased. I'm calling this one the "Coffin Ship Survivor" in reference to the coffin ships that would have brought Irish immigrants to America. The boat that would have brought them there would have been made of oak and the ancestors of those that would have survived the journey would have drank beer made with the Columbus and Cascade hops which give this beer its flavour.

Chocolate & Pale Malt
The 11kg Grain Bill

The malt bill is quite large for this brew as when I was originally making the recipe my efficiency was consistently in the 50% region or so I thought. Realising my errors in calculation I calculated my efficiency today to be 63%, I guess it would have been higher only I had to make a thicker mash so that I could fit all the grain into my mash tun.
Hop Bill
In the previous imperial stout I put in over 100g of hops at flame-out and dry hopped with another 100g.  Given that imperial stouts are meant to be aged for a while, this action is a bit of a waste of hops as the aroma would have diminished significantly in the several months that the beer would have been ageing. Instead I am putting in the hop additions earlier at 10 and 5 minutes with a small amount at flame-out to use up anything I had lying around.

#27 - Sylvan Blonde Ale [All Grain]

My parents recently moved into a new home which is quite close to a lot of trees. Given that there are several neighbours with the same first and last names as my parents, they needed to give the house a name to  help the postman identify who is who. After a lot of brain storming and thesaurus overuse, they finally settled on the name "Sylvan Lodge". Given that they like light flavoured beers and would probably be expecting a lot of visitors for the coming months I thought it would be a good idea to brew them a blonde ale. This recipe is based on the original recipe from homebrewtalk forums. 
First hop addition
The hops I used for this brew were both fresh from the 2012 harvest but even at that they would still be nearly 6 months old. Due to poor vaccuming (on my part) I decided to use the hop age too in BeerSmith to take into account the fact that they are 6 months old and haven't been stored that well. That is why when you see the recipe the AA values wont be what you would expect, they are slightly lower than normal. I wont know whether this has had a positive effect or not until I try the brew.
Normally I would dry hop but given that the target audience for this beer is quite conservative, I wont be doing it for this batch. Depending on its popularity I may do it in future versions which would be brewed for the summer.

The recipe can be found below:
