Friday night Greenbelt International Folk Dancing has gone "virtual". As we all practice good social distancing, many in our folk dance community are feeling the absence of our usually scheduled local dances. In response, please join us for the Greenbelt Virtual Folk Dance Session. Let’s keep dancing! • Connect and dance in our own homes • Watch hosts leading familiar dances • See each other; listen and dance to our favorites How: We will be using the ZOOM video conferencing app to share music and live videos of the leaders and each other. This can be used on a desktop, laptop, or smartphone. What to Expect: Your hosts are Linda Mansdorf, Vita Hollander, Ben Hole, and John Robinson. Collectively they will play 25-30 dances, which should approximate the number of dances normally done on a Friday night in-person event. The hosts will do a quick teaching or demonstration of the steps to some of the dances that may be less familiar to you or just as a refresher, but the session is not designed as a workshop, so the majority of the evening will be spent playing dances that many of us already know and love to do. How To Join Us: Each week we will send an email with the Zoom Meeting link ID. Make sure John Robinson knows you would like to receive this email with the link. John's email address for Info: j_srobinson@verizon.net. https://www.facebook.com/GreenbeltInternationalFolkDancing/ Co-sponsored by the Folklore Society of Greater Washington

It is a pleasure to announce that we have once again been invited to hold a spring event at the German Embassy! The German Wine Society’s Capital Chapter has held several asparagus-themed Spargelfest dinners at the Embassy, but this year’s Spring Gala event will offer something more, combining festive music with the pleasures of wine and food. We are collaborating this year with the International Club of DC to host this event, and so it is possible to register for the event through either organization at the same price. And this year, we are offering not only a dinner including white asparagus and with several German wines at the Embassy House, but also a reception and concert in the Carl Schurz Hall of the main Embassy building before dinner, with a selection of hors d’oeuvres and German sparkling, white and red wines. Guests will have the opportunity to attend just the reception, or the reception and dinner. For both the reception and dinner, cuisine will be provided by the German Embassy’s chef, Mikko Kosenen of Mikko Nordic Fine Foods. Chef Mikko also operates a restaurant in Washington, D.C., and was formerly executive chef for the Ambassador of Finland. Please plan to join us to share our love of German wine paired with white asparagus and other dishes, at the German Embassy where the German Wine Society began - and this year, to enjoy beautiful music and song at the start of our unique event, and to meet members of the International Club as well as those from our own Society! Please join our two groups at the German Embassy on the evening of **Friday, May 29, 2026,** from 5:30 pm to 9:30 pm. Our event will begin with a reception, introductory remarks, concert and wine tasting with hors d’oeuvres at the Carl Schurz Hall of the main Embassy building from 5:30 to 7:30 pm. After this, guests who have also opted to attend the dinner will ascend the stairs to the Embassy House (or use escorted access to the Embassy elevator for those needing assistance) for our buffet dinner and dessert from 7:30 to 9:30 pm. Our dinner will feature not only white spargel and an array of other dishes, but also seven fine white and red German wines, including Silvaner, known for its affinity with asparagus. Overall, seven of Germany’s thirteen wine regions will be represented in our reception and dinner, including the Mosel, Rheingau, Nahe, Rheinhessen, Pfalz, Ahr, and Franken. Registration for this event must be received by **Friday, May 22, 2026.** We can accommodate a maximum of 120 guests for the reception in the Carl Schurz Hall, but only 80 for the dinner at the smaller Embassy House. When registering, please decide whether you want to attend either the reception only, or both the reception and dinner (the price of the dinner includes the reception, and attending the dinner without the reception is not an option). For the first two weeks after initial announcement of this event, we are reserving half of the dinner places for those who register through the German Wine Society, at the listed price. After that time, all of the places will be available for purchase by members of either group, and prices will be subject to revision without prior notice. The initial price to attend the Spring Gala for members of the German Wine Society is **$95** for the reception alone, or **$195** for the reception and dinner; for non-members, the initial price will be **$105** for the reception alone, or **$205** for the reception and dinner. Reserve early to avoid disappointment! We anticipate being joined by members of the German Embassy staff, some of whom will provide introductory remarks at the reception. Please take the opportunity to mingle with them and share your interests in German wines and Germany! Here’s what we have planned for our Spring Gala: **5:30 pm: entry to Embassy compound passing through security (plan to enter no later than 6:30 pm); Reception and concert at the German Embassy.** Enter at the main Embassy gate on 4645 Reservoir Road, NW, Washington, DC 20007, and after passing through security, proceed to the Carl Schurz Hall in the main Embassy building. For security purposes, the Embassy requires a list of all attendees in advance; no walk-ins are allowed. Please remember to bring a valid picture ID. There is no parking available on Embassy grounds, but it should not be difficult at this time of day to find parking on the street nearby if you are driving. Be alert, however, to DC parking restrictions. The German Embassy is not near a Metro subway stop, but it is also possible to arrive by Metro bus (D94) or by taxi/ride service. Welcoming menu: hors d’ oeuvres + Sparkling wine served at main Embassy Pretzel bites with beer- cheese dipping sauce German bratwurst pig in blanket with mustard Asparagus-cheese quiche Herring on potato with mustard mayonnaise Duck confit arancinis with cherry sauce These hors d’oeuvres will be accompanied by the following sparkling wine: *Nv Dr. Loosen “Dr. L” Sparkling Riesling, Mosel.* In Germany, sparkling wine is known as “sekt,” and the Loosen estate produces this distinctive dry sekt using the Charmat method, with a specific grape and region rather than a generic blend. Rated 91 points by Wine Enthusiast. Introductory remarks will begin at 6:00 pm, and the concert will run from about 6:20 pm until 7 pm. The program for our Spring Gala Concert will be a joyous chamber music celebration featuring various German, Austrian and Italian works, performed by the trio Cantabile (violinist Christine Kharazian, cellist Irina Ponomareva, and pianist Nina Willner) and soprano Angela Mariano. Biographies of the performers are listed at the end of this notice. Music will range from the Baroque and other classical pieces, including Bach, Vivaldi, Beethoven, Handel, Schumann, and Mendelssohn, to traditional German songs of the Mosel and Rhine on wine themes. The program will include the famed 17th century German hymn Schönster Herr Jesu (as arranged by Dawson Hull), brought to America in the 19th century by German immigrants, with its references to springtime. During and after the introductory remarks and concert, the following red and white wines will be served as well: *2023 Spreitzer Oestricher Lenchen Riesling Kabinett, Rheingau.* The Rheingau region has long been identified with high-quality Rieslings, and this Kabinett, at the lower end of the scale of sweet wines, provides an off-dry or mildly sweet experience. Rated 92 points by Wine Spectator and Antonio Galloni. *2023 Kühling Gillot Spätburgunder Trocken, Rheinhessen.* The Spätburgunder grape is better known outside Germany as Pinot Noir, and this is a fine example of a dry red from a leading estate. 90 points average critic reviews. Guests attending the dinner after the reception should proceed up the stairway alongside the main Embassy building depicted here to the Embassy House on the upper level, between 7 pm and 7:30 pm after the concert. For those who have difficulty ascending the stairs, escorts from the Embassy staff can bring guests through the Embassy building and up an elevator. Guests not attending the dinner, but only the reception, should exit from the Embassy by 8:00 pm, but may remain after the concert until then to enjoy the white and red wines and hors d’oeuvres. **7:30pm - 9:30 pm Buffet Dinner with Served Wines: inside Embassy House cantina and possibly on patio also if weather permits** Assortment of bread Green salad with lingonberry dressing German style potato salad Pasta Salmon salad Grilled white asparagus with hollandaise sauce Roasted spring vegetables Chicken Schnitzel with lemon and capers Black forest ham Spaetzle with mushrooms, ham Sweets: Apple strudel with vanilla sauce Black forest cake Rice porridge with red berry soup The dinner will be accompanied by the following wines: Served as starters: *2023 Hexamer Helmut Meddersheimer Rheingrafenberg Rieslling Quarzit, Nahe.* A fine example of a barely off-dry Riesling from the Nahe region west of the Rhine, across from the Rheingau. Critic James Suckling rated the previous vintage 92 points. *2022 Rebholz Weissburgunder Trocken, Pfalz.* The Rebholz estate in the Pfalz region is one of Germany’s top producers of dry “Trocken” wines, in this case made from the Weissburgunder grape better known outside Germany as Pinot Blanc. Reviewed at 92 points by critic James Suckling. Served with main buffet course: *2022 Meyer-Näkel Spätburgunder (Pinot Noir) Estate, Ahr.* The small Ahr region near Bonn is more heavily focused on producing red wines, especially Spätburgunder, than any other wine region of Germany, with distinctive slate tastes. The Meyer-Näkel estate represents the 5th generation of winemakers. Critics have reviewed at 91 points. *2024 Carl Loewen Longuicher Maximiner Herrenberg Riesling Kabinett, Mosel.* Grown from vines over 120 years old in Devonian slate soil, and fermented in traditional wooden barrels (fuder). Rated 94 points by critic James Suckling. *2023 Wirsching-Iphöfer Silvaner Trocken, Franken.* A dry Silvaner white wine, served in the fat “bocksbeutel" characteristic of the Franken region, is the classic accompaniment to a spargel (asparagus) dinner. Rated 90 points by Kristen Bieler, Wine Spectator. Served with dessert: *2023 Fritz Haag Braunberger Juffer Sonnenuhr Riesling Spätlese, Mosel.* Spätlese wines are the next step up the sweetness scale in Germany from Kabinett, the term translating as “late harvest.” From the Sonnenuhr (“sundial”) vineyard., one of the iconic steep-sided vineyards lining the banks of the Mosel river. Rated 92 points in Wine Enthusiast. *2023 Dr. Loosen Ürziger Würzgarten Riesling Spätlese, Mosel.* The Mosel region, source of both dessert wines for this event, is one of Germany’s leading regions for the Riesling grape, and exports far more wines to the United States than any other single German wine region. From the Würzgarten (“spice garden”) vineyard in Ürzig. Rated 94 points by Master of Wine Anne Krebiehl, Vinous Media.
