  • Calories: 143
  • Carbohydrates: 12.4 g
  • Protein: 1.7 g
  • Fat: 0 g

Shiner Bock Nutrition Facts Compared to Other Beers

Compared to other popular lager beers, Shiner Bock is moderate in both calories and carbohydrates:

  • Coors Light – 102 calories, 5g carbs
  • Miller Lite – 96 calories, 3.2g carbs
  • Shiner Bock – 143 calories, 12.4g carbs

So Shiner Bock has more calories and carbohydrates than light lagers like Miller Lite and Coors Light, but slightly less than Budweiser. Among full-calorie lagers, it’s pretty average in both calories and carb content.

Factors Affecting Shiner Bock Nutrition

There are a few factors that can affect the nutrition content of Shiner Bock and contribute to variability:

  • Ingredients – The types and amounts of malt, grains, hops and yeast used in brewing can impact calorie and carb content.
  • Brewing process – Variations in the brewing process, fermentation times and filtration can lead to differences.
  • Serving size – Nutrition content is typically calculated per 12 oz serving. Consuming more or less will alter calories and carbs.
  • Draft vs bottle – Draft and bottled beer may have slightly different nutrition due to processing differences.

So there is some natural variability between different production batches and serving sizes. But overall, Shiner Bock averages about 143 calories and 12g of carbs per 12 oz serving.

Shiner Bock Carbs: Good or Bad?

The moderate carbohydrate content of Shiner Bock comes from the grains and malt used to brew the beer. Are these “good” or “bad” carbs?

The carbs in beer are a mix:

  • Maltose – A sugar that accounts for about half the carbs in beer. This acts similarly to other sugars and causes a blood sugar spike.
  • Dextrins – Longer glucose chains. These are digested more slowly than maltose and have less impact on blood sugar.
  • Fiber – A small amount of indigestible fiber from the grains used in brewing. This has no calories or impact on blood sugar.

So beer contains a mix of fast-digesting carbs like maltose along with slower-digesting dextrins and fiber. This means the carb content is not as bad as drinking 12g of pure sugar, but it will still raise blood sugar more than 12g of pure starch.

For people without diabetes or other blood sugar issues, the carbs in Shiner Bock are not necessarily harmful in moderation. But they may cause more spikes and crashes compared to eating slower-digesting carbs from whole grains and vegetables.

Tips for Drinking Shiner Bock on a Low Carb Diet

Here are some tips if you want to drink Shiner Bock beer on a low carb or keto diet:

  • Limit intake to 1 beer max per day. Even better, make it an occasional treat only.
  • Drink it with a low carb meal containing protein and fat. This helps moderate absorption.
  • Stay hydrated by drinking water before, during and after. This prevents hangovers and crashes.
  • Account for the carbs in your daily intake. Plan around the 12g carbs in your nutrition tracking app.
  • Switch to light beer (Miller Lite, Coors Light) or hard seltzer for lower carb options.

Drinking beer in moderation on a low carb diet is possible for some people. But it’s best limited to special occasions rather than daily drinking. Pay attention to how your body responds and adjust as needed.

Low Carb Beers Comparison

If you want to drink beer on a low carb or keto diet, here is how the carb content stacks up for some popular options (per 12 oz serving):

Beer Carbs
Miller Lite 3.2g
Coors Light 5g
Bud Light 6.6g
Michelob Ultra 2.6g
Shiner Bock 12.4g

As you can see, Shiner Bock is significantly higher in carbs than popular low carb beer choices like Michelob Ultra, Miller Lite and Coors Light. So if limiting carbs is your priority, those are better options.

Healthiest Beers

If you want to choose the healthiest beers, here are some good options:

  • Mich Ultra – Lowest carbs and calories
  • Miller Lite – Low carbs, moderate calories
  • Corona Premier – Low carbs, low calories
  • Guinness Draught – Low carbs for a stout, higher protein
  • New Belgium Fat Tire – Moderate carbs, higher fiber

In general, light lagers, low-calorie and low-carb beers are healthier options. They are lower in carbs and calories compared to full-bodied craft beers and stouts. But an occasional darker beer can also fit into a balanced diet.


To summarize key points:

  • Shiner Bock has about 143 calories and 12g carbs per 12 oz serving
  • It’s moderate in calories and carbs compared to other lagers
  • The carbs are a mix of maltose sugar and dextrins that raise blood sugar to varying degrees
  • Drinking 1 per day with a low carb meal is a reasonable approach
  • For lower carb options, choose light beers like Michelob Ultra or Miller Lite
  • Prioritize low calorie, low carb beers for the healthiest options

Shiner Bock can fit into a low carb lifestyle in moderation. Take a sensible approach, account for the carbs, and balance it out with low carb foods and hydration for best results.
