Schmidt Old Tyme 647 White Bread Review: Our Verdict

Short answer: We have tasted Schmidt Old Tyme 647 White, and it is the best-tasting low-carb bread we have tried so far. Of the lower-carb breads we have tasted, it comes closest to a conventional slice of white bread. If familiar white-bread flavor is your priority, this is a loaf we recommend. The current U.S. label lists 40 calories, 14 grams of total carbohydrate and 8 grams of fiber per 27-gram slice—6 grams of net carbs by subtraction. Our verdict is 4.0 out of 5 stars: a strong everyday option, with the main cautions being a long ingredient list, a substantial fiber dose and wheat as an allergen.

What is Schmidt Old Tyme 647 White Bread?

647 White is a sliced sandwich bread sold under the Schmidt Old Tyme brand in the United States. It aims to keep the texture and mild flavor of ordinary white bread while using added fibers and modified wheat starch to reduce digestible carbohydrate. The “647” name points to the brand’s headline numbers: 6 grams of net carbs, 40 calories and 7 grams or more of fiber per slice. The current product page actually lists 8 grams of fiber for the 27-gram serving.

That makes it a different proposition from breads that use mostly nuts, seeds or eggs. It still looks and functions like conventional packaged sandwich bread, and wheat remains central to the formula.

Nutrition facts at a glance

The manufacturer’s current U.S. label uses a serving of one slice (27 g). Here are the numbers that matter most when comparing it with another loaf:

Per slice	Amount
Calories	40
Total carbohydrate	14 g
Dietary fiber	8 g
Net carbs	6 g (14 g minus 8 g)
Protein	2 g
Fat	0.5 g
Sodium	140 mg
Total sugars	1 g, including less than 1 g added sugar

A two-slice sandwich therefore provides 12 grams of net carbs and 16 grams of fiber before fillings. That may fit a moderate lower-carb pattern, but it is not automatically a match for every keto target. If you track net carbs, our guide to reading bread labels and calculating net carbs explains the method and its limits.

Ingredients and allergens

The first ingredients are water, modified wheat starch, enriched flour, wheat gluten and sugar. The formula also includes soybean oil, salt, powdered cellulose, oat fiber, cultured wheat flour, wheat protein isolate, guar gum, whole wheat flour, vinegar, vegetable oils, enzymes, ascorbic acid, sunflower oil and sunflower lecithin.

Allergen check: the label says contains wheat. The manufacturer also says the product is made in a facility that processes soy. It is not suitable for anyone who must avoid wheat or gluten. People sensitive to large fiber increases should also notice the 8 grams per slice; trying one slice first may be more comfortable than beginning with a two-slice sandwich. See our practical guide to adding fiber without overdoing it at one meal.

Our tasting experience

We have tried 647 White ourselves. It is the best-tasting low-carb bread we have tasted so far and, to us, the closest to a regular, conventional slice of white bread. That familiar taste is its biggest selling point and the reason we recommend it to readers who want to reduce carbs while keeping the white bread they enjoy.

Our experience agrees with the recurring praise from Walmart reviewers, who commonly describe it as soft, close to regular white bread and useful for toast and sandwiches. Some also report occasional dryness, a separating crust or concern about the price. Those complaints are other buyers’ experiences; they are useful tradeoffs to consider alongside our own favorable tasting verdict.

The relatively thin 27-gram slice makes portion planning straightforward. Toast and sandwiches are practical ways to use it; avoid over-toasting if you prefer a softer bite.

What 647 White does well

• Familiar format: standard sliced white bread is easy to use for toast, grilled sandwiches and lunchboxes.
• Clear carb math: 14 grams total carbohydrate minus 8 grams fiber gives 6 grams net carbs per slice.
• Low calorie count: 40 calories per slice leaves room for protein-rich or flavorful fillings.
• Easy transition: the mild white-bread profile may appeal to someone who dislikes heavily seeded lower-carb loaves.

Where it falls short

• Not zero carb: two slices contribute 12 grams net carbs, so portions still matter.
• Modest protein: 2 grams per slice is less than some specialty high-protein breads.
• Long, engineered formula: modified starch, isolated proteins, cellulose and gums are doing much of the nutritional work.
• Fiber can be a lot at once: 16 grams in two slices may feel uncomfortable for someone who is not used to it.
• Wheat allergen: this is not gluten-free, and the facility also processes soy.

Who should buy it?

Choose 647 White if your first priority is a soft, mild sandwich bread and you can budget 6 grams of net carbs per slice. It makes the most sense for toast, egg sandwiches, grilled cheese, tuna salad or a half sandwich beside soup. Pairing it with protein, vegetables and a satisfying fat usually creates a more complete meal than eating the bread alone.

Skip it if you need gluten-free bread, want the shortest possible ingredient list, require a very low or zero-net-carb loaf, or know that large doses of added fiber bother you. For a much lower stated net-carb option, compare our ThinSlim Zero Net Carb Bread analysis; texture and ingredient tradeoffs differ, so the lowest number is not the only consideration.

Our rating method

We use a 5-star rating system. This 4.0 score weighs our firsthand tasting experience, the current nutrition label, ingredients and allergens, everyday usefulness and recurring customer feedback. Taste is its standout strength: it is our favorite among the low-carb breads we have tasted. The net-carb count, substantial added fiber and wheat-based formula still affect who should choose it. Our tasting verdict applies to 647 White; the other 647 products need their own reviews. It is not a medical score and does not guarantee an individual blood-glucose response.

Frequently asked questions

Is Schmidt 647 White Bread keto?

It can fit some people’s keto or lower-carb plans, but “keto” is not a universal serving rule. One slice has 6 grams net carbs by the current label; two slices have 12 grams. Compare that amount with your own daily target and the rest of the meal.

How much fiber is in one slice?

The current label lists 8 grams of dietary fiber per 27-gram slice. Increase fiber gradually and drink fluids according to your normal needs if your usual intake is much lower.

Does it contain gluten?

Yes. Wheat, wheat gluten and wheat-derived ingredients are listed, and the allergen statement says contains wheat.
