One of the things that I enjoy about attempting to clone a
beer is the process to come up with a recipe. The other nice aspect of cloning
is that you have the ability to compare your clone with the actual commercial
example. This gives you the opportunity to determine how close you are to the
commercial beer and determine what changes need to be made if your beer does
not taste like the clone. The more that
you brew the easier it is to determine how a beer should taste prior to brewing
it, but if you’re just learning the easiest way is to compare your beer to a
commercial example.
As usual I enjoy trying new techniques when I brew and this
time was no different. I needed to use pecans if I am to properly clone (512)Pecan Porter, but I wasn’t exactly sure how I was going to use them since they
contain head killing oils. I did a little research into the topic of using nuts
(pecans are fruits technically) that contain oils and stumbled across two
different methods. The first method was described by one of the employees from
Lazy Magnolia Brewing for their Pecan Ale and the second method was explained
over at ryanbrews.
Method 1- Roast the pecans at 400oF for 10
minutes and let them cool on a paper towel to extract oils, followed by
breaking them into chunks and repeating the roasting at 350oF for 30
minutes, finally after the second roast let them cool on a paper towel again to
remove oil. The point of roasting the pecans is to remove the some of the oil
from the pecans. After they have been roasted you will throw them in the mash
tun and mash as normal. To make up for the fact that there will be some of the
oils making their way into your beer you will need to either increase (or add) the
amount of wheat or crystal malt you’re
using to boost the head retention.
Method 2 – This method involves making an extract. In theory
you will preserve the essence of the pecans without the head killing oils. In
order to do this you need to roast the pecans just like in method 1 but instead
of mashing with them you grind them up (which causes them to turn into a pile
of sticky mush) and place them into a jar with a clean spirit (such as vodka). Over
time the oils will infuse their aroma and flavor into the vodka. When the aroma
has been infused you need to filter out the pecan bits and then take the
oil/alcohol mix, place a straw in it and freeze the mixture. When settled the
oil should settle to the top and freeze, while the alcohol will not freeze.
Once frozen, remove the straw and pour the alcohol through the hole that
remains, leaving the fatty oil behind. Continue to repeat until the oil has
been removed. You can add this mixture at bottling to your liking. A more
detailed explanation of the process can be found here.
I decided to go with method 1 assuming it will give me more
pecan flavor that (512) is known for and because I’m assuming the reason they use
“copious amounts of crystal malt” is because they mash with the pecans. I did,
however, also make the extract just in case I want to add some more pecan aroma
when I bottle.

Notes:
12/6/14 – Brewed with my Dad for part of his birthday gift. A
little low on the pre-boil gravity so I added 15 minutes to the boil. Mash pH
measured at 5.56, calculated value was 5.57. Ended up boiling off too much due
to my Dad’s different kettle geometry so the FG was 1.071 at 5 gallons. Chilled
to 80oF and added the yeast and it brought up the final volume to
5.25 gallons and the gravity to 1.068. Left to ferment in my parent’s house at ambient
temperature.
12/7/14 – Healthy fermentation going 12 hours later.
12/9/14 – Made the pecan extract.
12/27/14 - Bottled with 85 grams of table sugar. Added 4 ml of pecan extract for aroma. Gravity down to 1.015.
1/22/15 - First tasting. A little low on the carbonation.
