Mead update

The fermentation slowed to the point I decided to rack the contents and check the alcohol and sugar levels. The alcohol is at 8-10% and the sugar is still in the 22% range, which gives a slight alcohol taste and a LOT of sweetness left. In fact it’s too sweet, so I decided to filter out all the blackberry seeds and pulp put it back in the jars and ferment it some more. Filtering out the seeds is just a matter of some cheesecloth and a funnel.

Yup, made a bit of a mess with it, but that is to be expected, I can’t seem to do anything without making a mess. It’s on a second ferment and I’ll keep a close eye on the alcohol content to try and get the balance of ‘bite’ to sweetness that I want.

 

The red flame raisin mix is still bubbling away and the fumes coming out of the water lock smell like heaven. I’ll do a post on that soon when I get a taste of the results.

 

Continuing work part 2

I did quite a bit this weekend and didn’t think to get any pics of it. Just for the fun of seeing how it would turn out I stared the fermentation of 15lbs of red flame raisins in my main fermenter. It’s just the raisins, a couple pounds of sugar for starter, and the yeast. I’ll post more on it when I get the first taste and see if it was worth it. I also worked on the cast iron treadle base from the table project. I tried to braze one of the cracks but couldn’t get enough heat for the rod to stick and silver solder didn’t like the cast iron. I may have to get a specialty braze for it. The mead is still giving the occasional bubble in the water lock, so the ferment isn’t done yet. I am looking forward to pulling that batch and getting the first taste once it’s done, I’ll be posting that moment for everyone. And I spent Saturday morning partly on my Kenwood TS430S radio talking to people on 40m Ham bands and partly playing my bagpipes.

Yes, you read that right. Bagpipes.

 

I began the machining of a new valve guide for my 1929 Fairbanks-Morse hit-miss engine in part one HERE. It’s a couple weeks later and I felt like spending some more time on it, so here is the next bit in it’s making.

The inner bore where the valve itself rides is done, now I need to turn the outside down to be an interference fit with the reamed hole in the cylinder head. An interference fit means that the part to go in the hole will be just slightly larger than the hole itself so that the parts ‘wedge’ themselves together. They have to be a tight enough fit that when they get hot from running the engine, and expand at different rates, that they stay ‘wedged’. This also means that I have to turn the whole length of the guide to size, and I cant grab on to it with the chuck in the usual manner, instead I’ll have to hold the work piece from the inside while I machine the outside.

In the picture above you see the valve guide in the middle with and expanding lap on the left and a ‘live’ tailstock center on the right. The expanding lap goes into the guide bore and the center does the same from the other side. The pointy part of the center is mounted in bearings that allow it to rotate with the part it is contact with, thats why it’s called a ‘live’ center, it moves. All together in the lathe it looks like this.20151023_134638

Now that it is all in place it’s just a simple matter of turning the outside diameter down to size. Any machinists out there who look at the next picture, yes, I know that I’m cutting using the back side of the insert and it isn’t proper. I did it on purpose because there is just enough ‘spring’ in the insert holder that running the cut backwards gives a smoother finish. And since I need a fine finish for the press in fit, it works for me.

And the guide all finished inside and out, ready to be sized to length and pressed into the cylinder head.

Mmmmm…mead

We left off last night with our berries sitting in mounds of sugar and turning into something wonderful. Now it’s time to pull them out of the fridge and take a look at how they are doing.

20151011_154225

Thats looking good. See all that juice? That’s super food for the yeast, and it give our mead its flavor. The berries are good and soft, but they are still a little big for the yeast to process, so they go into the blender and get reduced to a thick liquid.

20151011_154429

All the juice and berries go into the blender, make sure to scrape the bowl clean. Excess sugar that may be in the bottom of the bowl goes in too. Then hit the button and you should end up with something like this.

20151011_154541

No one can resist putting a finger in that and seeing how it tastes. It’s like the sweetest blackberry jam, perfect for putting on a big bowl of vanilla ice cream…… but I wont. Instead I need to put it aside for the mead after just one more finger full….

Ok, now to the heart of making mead. We need 5lbs of honey. It needs to be raw unprocessed honey, cooking the honey or adding preservatives to it will change it so that the yeast won’t thrive. You can use raw filtered honey, I use the unfiltered because the brand I use doesn’t usually have any comb or other things in it needing to be filtered. Here’s what I use but any good quality honey will work.

20151011_153718

The other important thing is to make sure all of your processing equipment is clean. There are wild yeast all over the place and we want our yeast to dominate and be the only yeast processing the sugar into alcohol. So everything needs to be freshly washed and clean.

20151011_152408

I use water as hot as I can stand it with liquid detergent and a cap full of bleach to clean everything. A big bottle brush helps to get into the recesses of the 1 gallon containers and get them scrubbed out. Make sure to rinse well too, the bleach can kill off your good yeast just as quick as the bad yeast. Some people us campden tablets to sterilize their stuff, I’ve heard it can leave a taste in your finished product so I don’t. Try it if you want, its a personal decision on my part not to.

20151011_151819

When everything is clean, get your big ass pot up on the stove and get about a half gallon of water into it. Put it on low heat and get the temp to around warm bath water temp. I have filtered water on my house, but I still use bottled water to make my mead because of the mineral content in the water here. You want the water warm, but not hot, just warm enough to dissolve the honey in it but not so hot it scalds the honey. Once it’s to temp pour in your honey and stir until the honey is completely dissolved into the water. If it’s good honey you will be left with a honey water (it’s called the ‘must’) that is a nice deep amber color and still sweet to the taste.

20151011_154129

My my, that is nice. If you wanted to make a straight mead then you could just use the must (honey water) and yeast to make a true unflavored mead. I’ve done it, it’s nice, but I like my flavored meads and so do most who try them. So, since we are making a flavored mead, lets add the flavor..

20151011_154610

The blackberry mix is so thick and rich the few drops that fell look like blood on my stove.

20151011_154747

It tastes a lot better than any blood Ive ever tasted though, lol. Keep stirring the blackberry mix into the must until its well combined and a consistent temperature. Remember to not let it get too hot! just warm bath water temp.

20151011_154958

At this point I usually pour a little bit into a shot glass and enjoy the sweet concoction I have made. If you are going to sample it in this way do it now before the next step cause we will be adding the yeast to this happy new home we have made for it. Speaking of the yeast, better show you what I use.

20151011_155236

The yeast I use in my meads is Lalvin EC-1118. It’s a champagne yeast and produces high alcohol levels if given lots of sugar to eat and a favorable environment. Yeast can really change the flavor and alcohol level of your creations. I have used Fleishman’s bakers yeast and it works well, but it is less tolerant of the alcohol level and dies off at around 8-10%. This is good if you like a sweet wine, lots of sugars left over, but if you like a kick and don’t mind your stuff slightly dry go with the Lalvin. If anyone uses a different yeast that comes out well then drop me an email so I can try it too. On to the feast!

20151011_155301

That is the yeast just poured right on top. It’s warm, there’s lots of food, everything yeast like for a feeding frenzy. Well, except the light. Yeast aren’t particularly fond off light as far as I can tell.  That’s why I use the green glass bottles to ferment. Speaking of bottles, mine are all clean and ready to go with sanitized stoppers and water locks. Since the yeast don’t like light, stir them into the mix where they can re-hydrate and wake up.

20151011_153649

Next is to get the yeast and mix into the bottles where they can ferment in peace and make us a wonderfully intoxicating blackberry drink. I use a cut off funnel that I keep special for filling the 1 gallon containers and my small 1 liter casks (more on that in a later post).  Just make sure everything is clean and you are good to go.

20151011_155441

When filling the bottles don’t fill them to the top. The yeast can get aggressive in the fermentation and it causes a lot of carbon dioxide bubbles and agitation. If you fill them too full then your mead will end up coming out of your water lock or popping the stopper, a very bad thing. I fill mine about 2/3 full and it has worked well for me so far. Once you get the fluid in the bottles put the stoppers on.

20151011_155715

Next comes the water lock. There are three parts: the body, the bubbler, and the cap. The purpose of the water lock is to let carbon dioxide gas made by the fermentation process escape and not letting outside air with wild yeast back in to the container to ruin our work. It’s fairly straight forward. Insert the body into the stopper first.

20151011_155737

Next put the bubbler into place. This part moves and allows the bubbles to escape while keeping the outside stuff outside.

20151011_15574920151011_155810

 

Now fill the body of the water lock with… yup, water… until it reaches the line scribed in the body of the lock. This sets the proper water level to keep everything working like it should. You need to check the water level regularly through the ferment so that it doesn’t get low and allow outside air to get into your container. Finally, put the cap on top of the water lock. Don’t leave the cap off, I learned the hard way it’s a bad idea to leave it off.

20151011_155926

There it is. Two 1 gallon containers filled with blackberry love in the making. It will take about two weeks in a dark room-temp area (I use a my pantry closet) to complete the ferment. Make sure to check on the water locks every couple days and let the yeast do their job.

 

To make things easy I have some links to an online supplier for the equipment I used. All up: two 1 gallon containers, two locks, 4 stoppers, and three yeast packs is $20 plus tax and shipping. Not an amount that should stop anyone curious to give this a try.
