Bollinger also refers to Maison Bollinger, a historic champagne house based in Ay, in the Montagne de Reims subregion of Champagne, France. Founded in 1829, the house is known for Pinot Noir–dominant blends and for producing wines such as Special Cuvée, La Grande Année, and R.D. Bollinger is regarded as one of the traditional grandes maisons of Champagne, with a reputation for robust, ageworthy wines.

Bollinger Bands are a technical analysis indicator associated with the Bollinger name. Created by John Bollinger in the 1980s, the indicator uses a moving average and two bands set at standard deviations above and below the moving average. The bands expand and contract with price volatility, helping traders assess relative price levels and identify potential overbought or oversold conditions and possible reversal points.
