Funny story in The Derrick News Herald:

“Authorities in central Pennsylvania who were called to investigate a suspicious odor at an abandoned house thought they had found a meth lab.

It turned out to be an old winemaking operation.

Police in North Cornwall Township searched the home’s basement and discovered fivegallon pails and hundreds of glass beakers, jars and other containers filled with unknown liquids on Saturday.

Police say the items are consistent with equipment used in the manufacture of methamphetamine. But further tests and research led police to conclude the home’s former tenant, who died about five years ago, had been making wine in the basement.

Police re-secured the residence, which is owned by a man who police believe lives in nearby Lancaster.”

Might not have been so funny if there were real live people in the house, just making wine for Christmas though.

It has been awhile since I’ve updated the blog with my winemaking activities. The reason for that is simple: During the warmer months, I can be found more often on lakes and rivers with a fly fishing rod in hand, than in the winemaking room. I know many winemakers that start their wines in the summer and autumn when the fruit is being harvested. This means they are taking advantage of whatever local produce is available to them for their wine.

Well, I prefer to have the bulk of my winemaking activities when I can’t fly fish. I do start the odd batch during warmer months, but I really try to take advantage of the time that I have to do as much fly fishing as I can. Where I live, it is almost impossible to do that in the winter.

I’ll be quite busy over the next few weeks as I help my girlfriend (seems odd to use that word when your in your 40′s) move across Canada, but I do have some plans for some wines to start and articles to write. Soooo keep an eye out here! I have a couple of kits that I have not started yet, and also a promise of donations of honey from a local apiarist for some meads that I have in mind.

Have you ever looked at your airlocks popping up and down as carbon dioxide gas is being released and wondered just how much co2 you might be responsible for generating? There was an interesting discussion started by a user “Dhorton” at the WineMakingTalk forum who was wondering if there was any concern in regard to co2 amounts in their apartment as a result of making wine at home.

Apparently, since Dhorton began making wine, their smoke/carbon monoxide detector was activated a few times. I imagine the detector detects carbon monoxide specifically, and there could be a number of reasons for false alarms including humidity, dust and even bugs getting into the unit. But to a new winemaker, I can understand the concern seeing all these carbon dioxide bubbles coming up and wondering if the quantity is enough to affect the air inside.

An engineer, “Kiljoy” who admits to having too much time on his hands responded to the forum thread and figured that one gallon of wine with a specific gravity of 1.09 would release about .07433 lbs. of carbon dioxide per day over a 14 day fermentation period. The calculations then went on to show that this was a negligible amount, even in a small apartment.

Later in the thread, a link to a blog post that discussed carbon dioxide emissions by breweries was posted. In that post, Pablo concludes:

“Maybe this doesn’t sound like much, but let me put it in perspective: in 2004, Americans drank 23.974 billion liters of beer, resulting in 1,491,182 mT of CO2 emissions. Global beer consumption in 2004 was 150.392 billion liters, resulting in 9,354,382 mT of CO2 emissions. For a little something more to think about, the US emitted a total of 1,446,777,000 mT of CO2 in 1996. Now, keep in mind that this is based on an assumption of a brix value of 12. The average beer may be a bit weaker than that. Feel free to plug in your own assumptions to see what you get. Either way, the CO2 emissions from brewing are not negligible.”

Well, it seems to me that Pablo’s logic might be a bit off if he is suggesting that the brewing industry alone is responsible for this. Bare in mind that we are talking about emissions from the fermentation of organic material that contains sugars. I could be wrong, but I think that there would still be quite a bit of CO2 even if it wasn’t used in the brewing or winemaking industry – as the stuff rots it would likely release plenty of CO2. Humans release CO2 in their farts after eating organic plant material so either way – fermented or digested, or left to rot, CO2 will likely be produced. I’m just not sure if it would be in the same quantities – does simply rotting matter convert sugars to CO2? What I’m saying is that this plant material would release CO2 in time, whether it’s fermented or not.

In my opinion, trying to put some blame or pin global warming causes to include brewing or fermenting is a bit much. I don’t think home winemakers have anything to worry about, even if they do put great stock in theories about CO2 emissions and global warming.

I’m sometimes asked when I tell others that I make my own wine, “Ian, how can I make wine?” As someone else once wrote (I think it was Jack Keller, but I’m not certain right now) my response is “You don’t make wine. Yeast make wine.” Sometimes I find it amazing that these single celled organisms are responsible for the turning juice into a beverage that many of us enjoy for it’s flavors, aromas, and of course, gently intoxicating effects.

So, how to make wine? Well, considering it’s the yeast that consume sugar, turning it into alcohol and carbon dioxide, we get to control so much of the process however, including the type of yeast we are going to use. There are many varieties of yeast available to make wine today, and are selected for a variety of characteristics they have. Some have higher tolerance to alcohol and temperature changes, while others are more suitable for wines that are meant to finish sweet or semi-sweet.

Of course, in wine making, there is also the choice of the main ingredient. Will it be juice from grapes or other fruits? How about mead made from honey? Even vegetables can be used to make wine. Until someone has tried it, they may think that making a parsnip wine would be rather awful tasting, but in fact parsnip wine after some aging is quite nice.

When wine is being made, what we try to do is control the conditions as much as possible that the wine is being made in by the yeast we’ve selected. During and after the fermentation (and sometimes before fermentation starts), adjustments will be made to try to get the right acidity, sweetness or dryness, clarity, and the all important flavours and aromas.

If you are using a wine kit, you won’t have to worry about those adjustments – the concentrated juice you will receive has already been balanced and had the necessary ingredients added to complete a fermentation that will turn out similar to a wine purchased retail made of the same grape variety(s). And for the beginner, this is probably the easiest way to begin learning about how to make wine.

“Garlic wine?” you might ask with just a hint of incredulment. “Who would ever make wine out of garlic?”

One of the fun and interesting things about home winemaking is the fact that you can make wine out of just about any organic plant material as long as it’s not poisonous. And garlic wine is certainly something that you can make.

As far as drinking it for pleasure, that’s another matter. But, garlic wine makes an excellent addition to foods and salads. I wouldn’t advise pouring it into a glass and serving it to guests if you want your guests to return, but using it in a variety of dishes including beef, chicken and seafood will impress the tastebuds.

We’ve all heard about the health benefits of red wine. When the fermentation process starts, there are many chemical reactions going on with new compounds being created, while other compounds become more potent and concentrated. For example, the compound that may provide many health benefits, reservatrol, can increase when red grape juice is fermented. Red Spanish grape juice typically contains 1.14 – 8.69 mg/l while Spanish red wine contains between 1.92 and 12.59 mg/l. This increase may be explained by the fact that reservatrol is produced when the grape is under attack by bacteria or yeast.

There are no known studies that I am aware of regarding any compounds specific to garlic wine, however garlic has been known by itself to have many health benefits for those that consume it regularly. It has been said that the ancient Roman physician, Galen, used garlic wine to treat sick and injured gladiators successfully.

Whether or not there are health benefits to garlic wine, it does make for an interesting additive to gourmet meals. Making it yourself is quite simple if you have the right home winemaking equipment. You do of course need to bare in mind the important factors in making any kind of wine, the biggest being that of ensuring your work area and equipment are sanitized.

If you do plan on making garlic wine, I would not recommend anything more than a gallon at a time. Filling a five gallon carboy with garlic wine leave you with a predicament of what to do with it all as amounts needed in cooking are small. You could of course, bottle it and give it away as gifts to your dining friends. Just be sure they know it’s not a sipping wine!

You can find recipes for garlic wine as well as others wines that have interesting ingredients such as parsnip, ginger, blackcurrants and other fruit at this home winemaking site.

There will be lots of potatoes in my diet over the next little while. But being from Northern Ireland, I shouldn’t have any problems with that!

I was in an experimental mood today and thought I’d try a recipe for Potato Wine that I found in a book. But first, I needed to find some ingredients I did not have in hand: Citric acid and Amylozyme. Wasn’t sure exactly where I’d find them but on a hunch which turned out to be a good hunch, I called Bob over at Orangeville Winemakers. Sure enough Bob had the Citric Acid. “Amylozyme?” he asked. “What’s that for?” I told him it was an enzyme used to break down starches. “I have Amylase which does that.”

Yes, the same thing, I think. The book that the recipe is in was published in the UK so some terminology might be different. Now that I knew I could get the ingredients today, I planned on making the wine in the evening. Here’s the recipe for potato wine.
