What Flavor Is Surge?
A 1990s citrus soda that fans brought back from the dead, and a case study in how hard a revival really is.
What flavor is Surge?
Surge is a sweet, caffeinated citrus soda in the Mountain Dew style, with lime and orange the notes tasters most often name. Coca-Cola only ever called it citrus and has never named the oils.
Flavor profile
- Family
- Citrus
- Character
- Sweet lime and orange, softer and less syrupy than Mountain Dew by most accounts, light caffeine bitterness
- Key components
- Unpublished. A citrus soda of this type uses citral and limonene from lime and lemon oils, with orange oil and orange juice concentrate
- Impact
- High
- Typical dosage
- 0.10-0.20% in a full-sugar soda, usually as an emulsion
- Heat stability
- Poor; citrus top notes go first
- pH stability
- Moderate; citral breaks down in acid over shelf life
- Natural availability
- Natural citrus flavors are widely available; a natural bright green is very hard at soda pH
Surge was Coca-Cola's second attempt at Mountain Dew, after Mello Yello. It has had an unusual life.

Coca-Cola said the 2014 version used the same formula as before.1 By 2024, The Daily Meal reported that Surge was no longer manufactured.3 We found no Coca-Cola announcement of a second discontinuation, so treat its status as uncertain.
What it tastes like
Sweet citrus with a caffeine kick, in the same family as Mountain Dew. One reviewer of the 2014 cans picked out lime and orange, and found it smoother and less syrupy than Mountain Dew.2 Treat that as one taster's view. Much of what people say about Surge now is filtered through memory.
The orange note has a source. Surge listed orange juice concentrate, as Mountain Dew and Mello Yello do. The bright green came from dyes.
Caffeine was about 51 mg per 12 oz in the original. The 2014 16 oz cans listed 69 mg, roughly the same strength per ounce.
Bringing back a discontinued flavor
Surge is a good warning for any brand planning a revival. "Same formula" is harder than it sounds.
The raw materials have moved on. Citrus oils vary by crop year and supplier. The oils in a 1997 batch no longer exist. A flavor house can match the profile, but it is a new match, not a copy.
Some ingredients are gone. Rules change. Brominated vegetable oil was once common in cloudy citrus sodas. The FDA revoked its authorization in 2024.4 Any old formula that relied on it needs a new emulsion with a different weighting agent.
Memory is not a spec. People remember a drink as stronger, sweeter or more intense than it was. If you match the original exactly, some fans will still say it changed. Benchmark against retained samples if any survive. If none do, brief the flavor house on what people remember, and accept that it is a target, not a record.
The color is half the memory. Surge's green is part of how people recognize it. A natural green that holds for months at soda pH is a very hard brief, so settle the color before you tune the flavor.
Name it a citrus soda. Surge is a Coca-Cola trademark. A flavor house will list a copy as a "citrus soda type".
