Waste glass used as grape vine mulch PDF Print E-mail

A Christchurch winery says it is taste-testing the wine made from a block of vines on which it has experimented by laying beds of crushed glass to suppress weeds, retain soil moisture and improve ripening of the grapes.

The pilot project, a world first, is being conducted at Sandihurst Wines by Dr Glen Creasy, of Lincoln University, partly to find new ways to recycle thousands of tonnes of waste glass.

Crushed glass spread underneath the vines reflects sunlight back up onto the fruit to enhance ripening. The glass is the size of coffee sugar crystals and is safe to touch.

The trial started in December 2005 and results so far have shown it improves soil moisture retention, weight of grape clusters and weed suppression in the vineyard, and adds complexity to the wines -- in this case, pinot noir.

Some councils around New Zealand concerned about "glass mountains" of bottles and other glass which are uneconomic for recycling have been grinding down the waste and using it for things such as roading materials.

Other waste glass projects include trials into the use of crushed recovered glass bunkers on golf courses as an alternative to sand.

When the NZ dollar was strong, huge volumes of glass products were imported cheaply, rather than being made domestically, and much of the imported glass was clear "flint" glass that was less suitable to recycle.

Linda Norris, chief executive of the Sustainable Initiatives Fund, said the cost of transporting waste glass to Auckland, or Asia made it even harder for South Island councils.

"Trucking substantial amounts of glass waste to Auckland or shipping to Asia for a marginal return just doesn't make good economic sense," she said.

Every year 13,000 tonnes of waste glass is produced in Christchurch, much of it marginally recyclable.

"Finding a use for all the waste glass collected in Canterbury has been a real problem," said Ms Norris. "We've been looking for other uses that are viable."
Research winemaker Kerrie Stronge, from Hortresearch, is conducting the taste-test.

Dr Creasy said he liked the way using the glass under the vines was coming full circle, in that glass that is used in the wine industry could be crushed and used to improve the wine.

The Sustainable Initiatives Fund backed the Sandihurst project by putting in $25,000 to test the viability of using crushed recovered glass on vineyards.

The winery trial has used just 35 tonnes on a small block, but extending the crushed glass mulch to more wineries in the South Island would use much more. The glass can be crushed in a mobile crusher at the rate of 12 tonnes an hour.

Among the complex melody of molecules that create a wine's bouquet is another chemical signature - the consumption of fossil fuels.

Researchers from the Netherlands are investigating whether levels of fossil-fuel-derived carbon dioxide measured in the wine's alcohol could help track CO2 emissions in a given region.

They hope this may help determine which carbon-management schemes work best and refine regional models of climate change.
 
Wine-ology: Reds can mature; whites best new PDF Print E-mail

Are older vintages always better than younger ones?

Contrary to what you may expect, most wines today are made for consumption while they are still young (within a year or two of the vintage on the label) and will not improve much over time.

With red wines, you can generally bank on an older vintage having more complexity and smoothness than a younger vintage, especially for age-worthy grapes, such as cabernet sauvignon, merlot and blends containing these grapes.

Because red wines contain age-friendly tannins originating from contact with grape skins and stems, and from aging in oak barrels, they continue to develop and mature inside the bottle and become more drinkable over time.

 
Hairdressers face jail for offering customers mulled wine PDF Print E-mail

Hairdressers who offer their customers a festive glass of mulled wine at Christmas have been warned that they face six months in jail and a £20,000 fine.

The threat was made by council chiefs, who even announced that they will send officers into salons under cover in an effort to catch offenders. Hairdressers have criticised the move as "Scrooge-like".

Norwich City Council wrote to all hairdressing businesses in the city ordering them to get a licence if they want to serve alcoholic drinks.

Sent to 104 salons in Norwich, the letter states that the practice of serving complimentary alcoholic drinks is a breach of the law and requires various licences.

It then warns: "To address this issue enforcement action, including the use of undercover officers, may be undertaken in the near future."
The council also declares that anyone found guilty of unlawfully supplying alcohol could face a maximum of six months in jail, a maximum fine of £20,000 or both.
Nigel Matthews, owner of Nigel Alexandre salon, said: "The vast majority of salons serve tea and coffee throughout the year and in the couple of weeks before Christmas offer a glass of wine or mulled wine or sherry. It seems very Scrooge-like to send a letter out just as we are entering the festive period.

"It is traditional, the clients are rewarded and it is all part of the customer service.

"What struck me was the potential sentence – you get a lot less than that for a lot more than serving a glass of wine."

Jason Taylor, owner and director of Kinki which has two branches in the city, said: "If we were having parties and getting everyone drunk then I could understand but it is a token tipple, a stubby bottle of three per cent beer or a small glass of wine.

"And in these very tough times we need whatever help we can get."

Georgia Parry, who works in the Max Giammello salon, said it would no longer be able to offer champagne with its VIP package, which is available all year round.

She said: "Champagne and strawberries is a nice thing to have, and having to stop that brings the whole VIP package to a lower level."
A council spokesman said that under the 2003 Licensing Act "sale by retail" includes providing alcohol to customers as part of the service.

He added that a letter of complaint was received last month about salons offering drinks.

"We wanted to make sure small businesses did not unwittingly fall foul of the law while trying to spread a little Christmas cheer in the build-up to the festive season," he said.

Michael Stephenson, regulatory services manager, said: "We know that with the credit crunch all businesses need to do everything they can to encourage customers through their doors and will be offering various incentives in order to achieve that.

"We accept the letter we sent out to hairdressers in the city may not appear to be in keeping with the festive mood and are sorry if it has been misunderstood.

"However, we are a licensing authority and there is a serious message here about the enforcement of licensing laws and helping businesses make sure they do not fall foul of the law."

The threat was made by council chiefs, who even announced that they will send officers into salons under cover in an effort to catch offenders. Hairdressers have criticised the move as "Scrooge-like".

Wine is like a living thing and constantly changes with age. That's probably why quite a lot of wine tastes better even with only a few months in the cellar.

Many times when having friends for dinner or celebrating a special occasion, I find lots of pleasure and satisfaction in being able to choose a wine from my collection, taking out its cork and enjoying the benefit of age that has made the wine ready to drink.

For a wine to get better with age in the cellar, it needs to have three characteristics: flavor concentration, good acidity, and balance. It is important though, to understand that not all wines will improve with extended cellaring.

 
Thanksgiving Wine Pairing PDF Print E-mail

Finding the perfect date can be tough at times. But it’s a little easier to find a wine date for your Thanksgiving feast. There are all those “wine rules” you have to follow… right?

Forget about those stuffy rules and just drink what you like. Although one thing you should probably do is serve both red and white wines so your guests have a choice. You might even consider serving a sparkling wine if you’re feeling extra festive.

If you still need a little direction, never fear. I have consulted some folks in the wine industry to help guide us. With their help I’ve compiled a list at different price points, to fit almost anyone’s budget. The categories are $10-$20, $20-30, $30-40 and $40-$60.

I know some of you aren’t Americans and don’t celebrate Thanksgiving. But hey, if you can afford a tasty bottle of wine, then you have something to be thankful for. So consider cooking a turkey and inviting a bunch of friends and family over and share in the American holiday.
