If the Anglican Church is similar to the Lutherans, than Sherry will do just fine as it's made in a natural manner without adding spirits made from grain. Sherry uses white grapes for the base wine.
An article on Sherry in Wikipedia explains how it is made in a different manner than other wines:
After fermentation is complete, the base wines are fortified with
grape spirit in order to increase their final alcohol content.
Wines classified as suitable for aging as fino and Manzanilla are
fortified until they reach a total alcohol content of 15.5 per cent by
volume. As they age in a barrel, they develop a layer of flor—a
yeast-like growth that helps protect the wine from excessive
oxidation. Those wines that are classified to undergo aging as oloroso
are fortified to reach an alcohol content of at least 17 per cent.
They do not develop flor and so oxidise slightly as they age, giving
them a darker colour. Because the fortification takes place after
fermentation, most sherries are initially dry, with any sweetness
being added later. In contrast, port wine is fortified halfway through
its fermentation, which stops the process so that not all of the sugar
is turned into alcohol.
The old Lutheran liturgical rubrics encouraged the use of white wine for Communion. This was most likely due to thought that the church altar clothes would be easier to clean if a spill occurred. So, a blush Pinot Noir (Spätburgunder), Riesling, etc. was probably used most often.
In 1136 A.D., Bernhard of Clairvaux in Burgundy brought Pinot Noir for sacramental use in the Benedictine monasteries. Engaging in grape growing & wine making was part of the monastic tradition in the Middle Ages. The monks took the crafting of sacramental wine very seriously. Some of the best and most expensive wines in the world come from locations where the monasteries once existed.
Martin Luther enjoyed Rhine wine like Spätburgunder (Pinot Noir), but he also had a sweet spot for dessert wine like sweet (Generosos de Licor blended) Sherry. For example, he wrote a devotional thought on that type of wine.
Gott steht nicht mit dem Knüppel hinter Dir, sondern mit einem Glas
Malvasier vor Dir.
God is not behind you with a stick, but with a glass of Malvasia
(wine) in front of you.
In America, sacramental wine is often made from the Mission grape. It is fortified with extra sweet must (i.e. last harvest grape juice, raisons, etc.) being added during the fermentation process to bring up the resulting alcohol level. The adding of everclear (at 195 proof) is not acceptable, in making Catholic sacrament wine, as it is not natural being made from grain. Bottom shelf brandy is less expensive to use when fortifying wine, but the end quality is not conducive to making good wine. That is why fortified sacramental wine is often more expensive than other wines.
According to an article on Sacramental Wine in WineMaking magazine the following is noted. I have yet to verify the designer yeast comment and am very skeptical of it being a binding canonical law:
After extensive research into the Church Canon Laws that pertain to
the production of sacramental wines, I learned they had to be made
from 100% grape juice and could not contain any additives, including
Mission grapes were first brought to America by the Catholic missionaries, most likely from the Canary Islands of Spain. It is a red grape, but made into a blush wine (Angelica) for sacramental use.
Randall Grahm writes:
The mission grape was likely the first grape imported to California by
the Spanish padres in the 16th century, and for several centuries a
mainstay of California vineyards. I’ve tasted mission grapes at UC
Davis, and observed the famous Winkler vine before its untimely demise
due to tractor blight (and possible over-irrigation). I’m here to tell
you that as far as grapes go, mission is quite possibly the very worst
extant vinifera variety. It has an absolutely giant cluster, with no
color, no flavor, no acid, no nothing. And yet…under these bizarre
growing conditions in the Canary Islands, it produces a wine of
The take-home message? The world of wine exists in non-Euclidean
space, and certainly partakes of the quantum universe; there are great
discontinuities in what we know or imagine we know.
For sacramental Christians, of the Lutheran/high Anglican tradition, what is most important in the sacrament is not the type of wine or how much alcohol is present. Rather, it is how in the words of institution Jesus comes with his (super-substantial illocal) body, blood, soul and Divinity. His presence is distinct, but not separated from the primal elements of bread & wine. Bad wine can remind us of the cross he died on & good wine can remind us of the wedding of Cana and the eschatological feast to come.
