How to clean your glassware

Glasses should always be washed carefully, preferably by hand. Our glasses are 100% dishwasher safe, excluding special marked glasses, but they are best cared for by avoiding harsh detergents and choosing a cool, short dishwashing cycle. To avoid detergent residue, rinse glasses thoroughly in clean water. When drying the bowl of the glass, avoid holding the glass by its stem or base as this can, in extreme cases, cause the stem to break at its narrowest point.

Cloudiness of glasses in the dishwasher can have two different causes. The most common turbidity is deposits of lime or detergent residues. These can be easily removed with weak acids (e.g. citric acid or vinegar). However, there are also turbidities which, according to current knowledge, are not deposits but represent changes in the glass surface. These turbidities cannot be easily removed with household products, as they are the result of glass components being released from the glass surface.

Glass is a material that delights the owner with its brilliance and transparency. However, these properties are also responsible for the fact that damage to the glass surface - even if only minimal - becomes directly visible. Thus, a lasting cloudiness of the glass is already clearly visible to the observer if the glass is attacked only at a depth that is a thousand times thinner than 1 mm. In principle, every glass is subject to this optical change process over time. The reason for the formation of the cloudiness is often difficult to trace - however, it is possible to counteract the formation of such surface damage during machine dishwashing.

Caring for your RIEDEL crystal

  • All RIEDEL glasses are dishwasher safe!
  • RIEDEL exclusively recommends Miele dishwashers.
  • To avoid scratches: Avoid glass contact with other glass or metal. If available use a stemware rack.
  • To avoid stains: Use soft water (low mineral content).
  • To remove stains: Use white vinegar.
  • If washing by hand, wash the glass under warm water (use detergent and rinse the glass carefully).
  • Wash cleaning towels at boiling temperature (to kill bacteria) with odorless soap.
  • Never use linen softener when rinsing your cleaning towels (to avoid grease film on surface).
  • To polish the glass: Use two towels, never hold the glass by the base to polish the bowl as the stem could snap due to mishandling.
  • Avoid storing glasses in kitchen cabinets next to items with a strong odour, as this can taint the glass and have an effect on the wine‘s aroma.

Adjusting the dishwasher - Make sure that your dishwasher is optimally set.

This means:

  • Rinsing: Your rinse aid must be dosed in an optimal or sufficient quantity. Please make sure that your dishwasher is always sufficiently filled with rinse aid.
  • Water softening: Extremely soft water is aggressive to glass. The water softening system of the dishwasher must therefore be adjusted to the hardness of your household water and should correspond to a value of approx. 3 - 4 degrees German hardness (°dH).
  • Temperatures / program selection: You should select a low temperature program (50 - 55°C) when washing glass or, if available, a special glass program.
  • Steam: After rinsing, you should open the machine door briefly to allow moisture to escape, as water vapor can accelerate clouding of the glass surface.
  • Food residues and fruit juices: Excessive amounts of food residues, especially large amounts of fruit acid as present in juices, change the composition of the rinsing liquor and thus the conditions of the rinsing process. Washing glass and household utensils made of aluminum (e.g. garlic press, pots with aluminum handles, etc.) together should be avoided at all costs.
  • Non-dishwasher safe materials: Avoid washing non-dishwasher-safe materials, e.g. aluminum and earthenware. This causes chemical reactions between the aluminum and the glass surface, which extremely accelerate the clouding process of the glass.

To avoid any cloudiness, it is best to always rinse the glasses immediately after use so that no wine residue can build up. Red wine is particularly susceptible, as the acid will eat into the glass if the residue remains in the glass too long.

How to clean your decanter

The ideal is of course to fill the decanter immediately after use with warm water to the brim and let it stand overnight. The next day, remove the water and then fill the decanter with about ½ l of distilled water. Swirl the decanter with the distilled water in it and then pour it back out. Then allow the decanter to dry and polish it on the outside with a microfiber cloth.

To avoid any cloudiness, always wash out the decanter immediately after use so that no wine residue can build up. Red wine is particularly susceptible, as the acid will eat into the glass if the residue remains in the decanter too long. Water and citric acid or vinegar essence can also be used to clean the decanter while swirling it. If contamination does occur, you can also try some cleaning tabs.

We are offering cleaning beads, which can aid in removing tough inside the decanter. Simply add them slowly through a funnel with some warm water into the decanter and swirl them around foru about tow minutes. When you are finished strain the beads into a mesh colander, rinse them, dry them, and store for future use. 

Please be aware that our Bottle Cleaner (cleaning beads) cannot be used in the following decanters as they can become lodged in the design: Ayam, Amadeo, Eve, Escargot, Curly, Boa, Black Tie, Mamba, Horse, Horn, Tyrol, RIEDEL Winewings, Swan and Face to Face.

Please also note that only decanters from the current price book are listed. You can find a list of all decanters in our product overview with detailed information on the product detail pages. If your decanter is not listed, please contact our customer service team.

Beverages & Glasses

Serving to maximize enjoyment

  • Glass hygiene: Serve beverages only in sparkling, clean, odorless glasses.
  • Serving temperature: Before decanting and/or serving wine, please store it at appropriate temperature (red wines at 59-63 degrees F, 15°-17° C, white wines at 50-54 degrees F, 10°-12° C). The proper serving temperature enhances the quality of the wine by allowing it to fully develop its characteristic aromas and flavors. Do not over-chill white wines and sparkling wines, serve red wines below room temperature.
  • Serving per glass: Maximum 3 to 5 oz/100 to 125 ml: Never overfill the glass. Or fill the glass only to the widest diameter of its bowl. This will ensure maximum development of the wine´s bouquet, and also provide the most elegant table setting. The ample, gracious glass volume offers great wines the room to breathe and to express their unique aroma message. 
  • Holding stemmed glasses: The appropriately filled glass should always be held by the stem rather than the bowl, as heat from the hand could raise the wine‘s temperature above its optimum and negatively influence the bouquet of the wine. Stemless glasses should be held at the base of the glass.
  • Swirling the glass: Carefully swirling the glass allows oxygen into the wine by increasing its surface area and helps release the wine´s rich, mature aroma.
  • Why and how to decant wines: To decant wine means to transfer it from its bottle to a decanter or carafe before drinking. During storage or aging, wine can develop a solid deposit or sediment at the bottom of the bottle. Decanting is an easy means of separating the sediment from the wine. Decanting also helps the wine breathe, as the greater surface diameter of the decanter lets more oxygen reach the wine than the bottle‘s does. Red wines should be decanted well before serving and allowed to rest at room temperature for up to one hour to allow the wine to fully develop its bouquet.
