Alphalpha dog

Note: This is the inaugural article from our beer writer, Richard Pliny!

Ithaca Beer Company Excelsior! Alphalpha

Style: Double Honey Bitter
Color: Amber
ABV: 8.5%
Price Point: $11

Technical Notes: Brewed with local alfalfa honey and Cascade hops. Like the other Excelsior! Beers, this is bottle conditioned and the last pour includes a bit of yeast.

Hedonic Notes:
The first pour is very frothy and carbonated, a thick and stable head develops instantly. A slight cloudiness makes the honey amber beer a bit opaque.

Citrus-hoppiness pervades the aroma with a Belgian ester/clove scent forming the backbone. The scent is clearly Cascade hops. Orange and lemon scents make the bulk of the citrus sensation. The hoppy aroma is not as dominating as one might expect from a double IPA, or “double honey bitter,” but the citrus dominance of the Cascade hops is appropriate for the style.

As expected, the beer has a good deal of hoppy bitterness. Surprisingly, the brewers were able to get an earthy bitterness that is almost uncharacteristic of Cascade hops. A citrus and grass/hay-like flavor lingers on the palate. The earthy and citrus characters balance one another creating a well-rounded bitterness. A good amount of roasted and caramel malts were used, imparting a sweetness to the finish. Honey, too, adds a bit of sweetness in the finish, but is noticeable far more in the texture than flavor.

Somewhat sweet texture with a bit of maltiness constitutes the bulk of the mouthfeel. Initially the carbonation is very high, but it subsides quite quickly leaving a nearly flat texture within almost 20 minutes when served at the proper temperature. A honey softness is present in the finish, but it is a bit difficult to notice.
The beer is more palatable than most double IPAs, though if it’s overwhelming bitterness you are expecting then this beer may not be for you. For having used only Cascade hops, the beer has a remarkable range of hoppy bitterness, including not only the expected citrus notes, but also a refreshing earthy hop flavor in the finish. The bitterness is backed up by a wonderful fruity ester and clove flavor reminiscent of a Belgian Enkel, providing a wonderful balance. The alcohol content is listed at 8.5%, but the malt character balances it quite well and hides the solvent like character. Exceptional balance and a well-defined hop character make this beer a pleasure to drink.

Rating: corkcorkcorkhalfcorknocork 3.5 out of 5 corks .

Science!

Hops are used to create a bitter flavor in beer. From their early adoption as a means to curtail bacteria growth as an alternative to expensive spices, hops have become a flavor additive in modern beer. Current trends in brewing have seen the pursuit of extraordinarily bitter beers. New hop strains and even some techniques to increase hop oil solubility have created beers that reach the limits of not only the hops but also the human palate.

R group Compound Solubility Flavor
Humulone CH2CH(CH3)2 Lower Soft bitterness
Cohumulone CH(CH3)2 Moderate Harsh bitterness
Adhumulone CH(CH3)CH2CH3 Lowest Not understood

Alpha acids provide the bitterness in hops.
On the right is the generic structure for an alpha-acid.  Depending on the structure of R, the compound has a number of different properties.  Solubility is directly related to the size of the hydrophobic group in the domain represented with the R.  Cohumulone is often considered to impart an unpleasant bitterness.  Noble hops (the four original varieties native to Europe that tend to have high aroma and low bitterness) tend to have high cohumulone levels relative to total alpha acid concentration.  This is often perceived as an astringency in the beer.  Traditional Czech pilsners often feature this particular attribute quite well.  By contrast, humulone is the commonly recognized bittering agent in hops.  Adhumulone’s role in bittering is not fully understood.

Announcing our new beer writer!

Hey folks!

I am proud to announce a new staff member here at Ithacork.

Richard Pliny

From his first sip of beer, Richard Pliny was captured by the fizzy drink’s allure. Through years of research and experimentation he has sought to understand beer’s secrets, as indeed he still does. Now an amateur brewer and professional scientist, Richard seeks to share his passion for the drink with others.

Currently, Richard is also pursuing his PhD in Chemical Engineering. He exploits his university’s resources to further his knowledge of brewing and fermentation whenever he can, drawing heavily on the strong food science program. Like me, Richard has found that a basic understanding of biology and chemistry greatly elucidates the beermaking process.

Richard’s first post, fittingly on an Ithaca beer, will go up Friday in what will hopefully be a weekly beer column for you hopheads out there.

Please join me in welcoming Richard to the team.

Ice, Ice, Baby, Two Cold: A pair of Sheldrake Point ice wines

Recently, I had a chance to “help” with (more like “observe”) the Sheldrake Point ice wine harvest. I picked a few grapes then helped get them into the press for a two-part feature I would write for the New York Cork Report. I was given some sample bottles to aid in my efforts, which are reviewed below.

Sheldrake Point Cabernet Franc Ice Wine 2008

Two delicious ice wines.

Appellation: Finger Lakes
Grape: Cabernet Franc
ABV: 12.5%
RS: 16.2%
Price Point: $45
Closure: Natural cork

Technical Notes: Harvested January-February of 2008, so really grapes from the 2007 vintage. Frozen on the vine and pressed while still frozen. Averaged about 39 Brix after pressing. Final TA: 8 g/L.

Hedonic Notes: Beautiful color, a salmony red. In Strawberry City, this wine is the mayor. Dried strawberry character on the nose, like you’d find in a granola bar. Some spicy character on the nose as well. Mouth-coating but not overly syrupy. You can tell that it’s wine as alcohol definitely registers. Sweet (duh) but the sweetness is parried by acidity. Finishes like old-timey candy, like a mix of strawberry hard candy (those ones that the wrapper looked like a strawberry) and a honey stick.

Rating: corkcorkcorknocorknocork 3 out of 5 corks for a unique wine that’s fruity and balanced.

Sheldrake Point Riesling Ice Wine 2007

This was practically the first review I ever wrote for the blog, and amazingly it pretty much matches up with my tasting notes this time around. The first review is reproduced here for your convenience.

Sheldrake Point 2007 Riesling Ice Wine
Grape: Riesling
ABV: 12.6%
Residual Sugar: 16.5% (165 g/L)
Appellation: Finger Lakes
Price point: $65 for 375 mL (half-bottle)
The 2007 looks pretty much like any normal riesling would, pale yellow in color, though noticeably thicker in the glass on swirling. It also smells like a Finger Lakes riesling, with characteristic light floral and citrus notes. Also, it’s got a little stonefruit (I wrote “peach”) and pineapple thrown in there. On the palate, lively acidity stands up to the considerable sweetness very well, for a very fresh, zingy feeling. Lemon and lime join the party on the palate, kind of like Sprite. (Interestingly, all of these wines have quite a bit more sugar than Sprite [~110 g/L]). Really great, and not just for dessert. This {well-balanced} wine plays nicely with blue cheese and walnuts, and would likely compliment spicy foods (e.g., Thai or Indian) pretty well.
Rating: 3.5 corks corkcorkcorkhalfcork

In addition, some technical notes on this one: TA 11.2 g/L (that explains the “lively acidity” I suppose). Surprisingly high for an ice wine, but it’s a real asset in this case. 38 Brix at pressing. The current info I have notes the RS at 18%, which is also what it says on the bottle itself.

Like I said, on retasting, I agree with all these notes. I would add that the tiniest bit of oxidation (barely noticeable) creeps in on the tail end of a very long finish, but overall it’s an excellent wine.


Science!
I covered a bit on the science of ice wine production in 2 articles for the New York Cork Report. They can be found here:

Ice Wine Science Part 1: Volatile Issues treats the overall practice of harvesting ice wine grapes, and the somewhat surprising reason that ice wines and other high-Brix wines can have high {volatile acidity}.

Ice Wine Science Part 2: Frozen assets tackles the honey-like mouthfeel and unique aroma compounds that ice wine brings to the table.

Restless natives

During the hiatus, I wrote up mini-reviews of some hybrid wines for the New York Cork Report’s “What We Drank” feature. They were Niagara and Catawba based wines.  I have added them to the growing list in my quest to drink 100 different hybrid grape varieties.

Red cat, red cat...

The reviews can be found here:

Mazza Vineyards NV Niagara
Hazlitt 1852 Vineyards Red Cat (Catawba)

I talked a bit about Red Cat when I was at the Finger Lakes Wine Festival (see video clip).

These grapes, along with a few others like Concord and Delaware, are commonly known as “native grapes”.

However, “native grapes” is a bit of a misnomer.

Science!

Ampelography is the study of classification of grape cultivars. Ampelographers trace the ancestry of grapes by looking at similarities in leaf and berry characteristics and more recently by DNA fingerprinting.  For example, ampelographers recently discovered that the mother of the noble Chardonnay was in fact the reviled Gouais Blanc grape, which was banned in France for producing inferior wines.

A perfect grape flower. The stamens (male) are on the outside and the stigma (middle) leads to the ovary. Welcome back to 7th grade science class. Image: Bruce Reisch, Cornell Grape Breeding Program

Niagara, the white grape typically found in Welch’s white grape juice, is a intentional cross between Concord and the white Cassady grape. Catawba’s history is somewhat less clear, but it is believed to be an accidental cross between wild V. labrusca and V. vinifera. Even Concord is widely believed to have vinifera parentage.

Evidence of the vinifera ancestry of these “native” grapes includes the fact that they are perfect-flowered. This means that their flowers possess both male and female parts and the plants can fertilize themselves. Flowers of wild grapes, including wild V. labrusca, are pistillate, meaning they have either male or female parts.

Perfect flowering was likely selected for by growers, since self-fertile grapes produce much more fruit (no need for donor pollen to float over to the flowers).   Of the Vitis species, only cultivated vinifera, which went through thousands of years of selection by humans before meeting up with native American grapes, are perfect-flowered. A few non-perfect-flowered grapes are grown today, but they are largely heirloom varieties and not commercially important.

Anyway, back to the names.  Some people refer to these native-like hybrids as “Vitis labruscana” or labrusca-type grapes.  If you call them “native grapes,” people will know what you’re talking about, but it’s not quite accurate.  I have tasted REAL native grapes, including wild V. labrusca and V. riparia.  They taste like crap.  Wild labrusca grapes are extremely foxy (practically inedible) and riparia, which grow abundantly pretty much everywhere, don’t really taste like much of anything.

More info on grape breeding can be found at Bruce Reisch’s Grape Breeding Site.

Ithacork will rise again!

Hey gang,
I’ve been hiatus for a couple weeks now, and it’s high time I explained myself.

I am in the process of converting this ithacork.wordpress.com site into a new-and-improved ithacork.com.

Over the holiday season I will be setting up the new WP.org site (which provides SO much more freedom as far as templates/plugins, etc.) with a whole new look, and a whole new content schedule for more reliable wine reviews, science content, and more!

There’s nothing at ithacork.com as of now, so… don’t go there yet.

I will likely leave this WP.com site up as a placeholder for a while to direct traffic that way.

This move has been made possible by the fine folks at Palate Press: The Online Wine Magazine. I have made some monthly contributions over there and have even been roped into some editing. Look for some new science content there from me in the next week or so.

Also, I have still been contributing on a bi-weekly basis to The New York Cork Report, so check that out as well.

In the meantime, I will still be on twitter, blabbing about wine and other assorted stuff.

Thank you, readers, for supporting this site and giving me the impetus to make this next big step.

The soul of Witte

Brewery Ommegang Witte

ommegang witte

Style: Belgian-style Wheat Ale with Traditional Spices
Color (light, amber, or dark): Light
ABV: 5.1%
Price Point: $7.50/750 mL bottle
Closure: Cork with cage. The yeast sediment in the bottom is a clue that this bottle’s carbonation comes from a fermentation in the bottle, thus the need for the extra pressure protection of the champagne-style cork and cage.

Technical notes: From the website: “Witte is brewed with malted and unmalted wheat, barley malt, a light hops addition and spiced with sweet orange peel and coriander. Though adding a slice of citrus fruit is common while enjoying a wheat or Wiess [sic] beer, we feel that Witte’s gentle spicing and slight tartness renders the fruit superfluous.”

Hedonic notes: Pours with a lot of long-lasting foam. (Some people think that the foaminess of a beer is indicative of its quality. I’m not so sure, but that’s fodder for another post.) Smells of a little orange at first, giving way to some spicy, phenolic, medicinal tones and finally some plain old grain/malt. On the palate, tart, with lemon peel and tongue-numbing clove*. Very refreshing and light. After a long while, some curry appears on the finish. Likely a great summer beer (whoops, it’s definitely fall. Maybe this should have been on sale!) I agree with the brewery’s assessment that a slice of orange or lemon would be a bit much.

Rating: corkcorkhalfcorknocorknocork 2.5 out of 5 corks . It’s OK.

Ithacork breaks into the world of beer (finally!). I don’t know how it took this long! The Ommegang Brewery in Cooperstown makes some quality Belgian-style beers. I’m not sure of their nationwide distribution, but around here, beers like Hennepin, Rare Vos, and Three Philosophers are ubiquitous. Cooperstown is a little over 2 hours east-northeast of Ithaca (and on the way to Boston). Maybe I will stop by the brewery on my next trip with Sarah out to Plymouth.

*Science!
One way that beer brewing is different from winemaking is that brewers have a seeming ability to throw all kinds of fruit, spices, or other stuff (coffee, pumpkin, jalapeño, etc.) into their product and still have it be called beer. However, spice aromas and flavors in beer don’t always come from the spice rack, the mysterious East, or the sandworms from Dune. In the case of most Belgian brews, the yeast can add a spicy character as well. The molecule I’m talking about here is 4-vinylguaiacol (4-VG). It’s one aroma component of cloves, (the major one is eugenol, found as a lignin degradation product in oaked wines, but not common in beer) and if you are old, you may have smelled it at the dentist’s office (clove oil has a slight analgesic effect, so it’s used as a numbing agent).

240px-2-methoxy-4-vinylphenol

4-vinylguaiacol. Descriptors: clove-like, smoky, curry

Brewers are generally very protective of their yeast strains, and many breweries propagate their yeasts from previous batches. In this case, only certain strains of yeast (called Pof+, or “phenolic off-flavor” positive) have the ability (activity of the enzyme Pad1) to synthesize 4-VG and its counterpart 4-vinylphenol (medicinal/Band-aid) from hydroxycinnamic acid precursors. 4-VP and 4-VG are also the aroma precursors of {Brettanomyces} aroma compounds 4-ethylphenol and 4-ethylguaiacol in wines. (Van Beneden et al., “Formation of 4-vinyl and 4-ethyl derivatives from hydroxycinnamic acids: Occurrence of volatile phenolic flavour compounds in beer and distribution of Pad1-activity among brewing yeasts”, Food Chemistry, 2007).

Basically, Belgian witbiers and German hefeweizens have this clove aroma because of the strains of yeast that are traditionally used to ferment them. PS: The difference between a witbier and a weizen? Witbiers are often made with unmalted wheat, while weizens are made with malted wheat.

Hybrid genetics

Picture 14

The pedigree of Noiret, a recently released Cornell wine grape.

An article I wrote for the New York Cork Report is generating some interesting debate. Seems like there are strong opinions on both sides about hybrids. Essentially, the location of a gene contributing to color synthesis in hybrid grapes is located near the gene responsible for the “foxy” (Welch’s grape juice) aroma of labrusca-derived hybrids. Thus, a simple screen for diglycosylated anthocyanin could be a screen for potential foxiness in these grapes, enabling breeders to monitor and control this “grapey-grape” trait, which some consumers find off-putting. Check it out here.
