Pesach Shiurim for Matzah & Wine – For Healthy Individuals and for Diabetics / Those with Food Allergies

Updated April 2022

The challenge of diabetes seems ten-fold when it comes to Pesach. There are a whole new set of considerations – among them, four cups of wine at each Seder; a many-hour wait until Shulchan Aruch; and knowing the carb content of a single hand matzah.

These are real concerns for people with diabetes and related health issues who wish to fulfill the requirements of Pesach al pi halacha without compromising their health. STAR-K has turned to the Jewish Diabetes Association (JDA) for answers, and the JDA has kindly provided the following guidelines to help you prepare your matzah and wine.

NOTE: The following are guidelines for achilas matzah and arba kosos for both healthy individuals and for those challenged with diabetes or food allergies. When in doubt, consult with a rav.1a

I. Matzah

The stipulations for minimum shiurim for matzah, which follow, are based on the psak of Rav Moshe Heinemann, shlit”a. These shiurim are different than listed prior to 2020. [Refer to “Halachos of the Pesach Seder” HERE for more information.] These calculations are based on the use of a Pupa Tzelem hand matzah (10 matzos to a pound).

In the case of a medical condition (e.g., diabetes, food allergies) which could be negatively impacted by matzah consumption, one may fulfill the mitzvah of Achilas Matzah, Koreich and Afikomen, with the following 1:

TypeMinimum ShiurDimensionsCarbs
Hand matzah (round)one-quarter (1/4) of a matzah21.7 sq. in. in size.29 g
Machine matzahone-quarter (1/4) of a matzah12.25 sq. in. in size.38g

One who is in good health should eat the following for Achilas Matzah 4 and Afikomen:

TypeMinimum ShiurDimensionsCarbs
Hand matzah (round)one-half (1/2) of a matzah43.3 sq. in. in size 518 g
Machine matzahone-half (1/2) of a matzah24.5 sq. in. in size 615 g

How to calculate the amount of carbs in Matzah:

Machine Matzah

Most machine matzah is uniform in size and shape. The portion size and carbs are listed on the box. It might be a good idea to keep the amount that you intend to eat near your plate.

Hand Matzah

Hand matzah varies according to size and thickness. Our calculations use a Pupa Tzelem hand matzah. Try to arrive at an accurate gram content for the matzah in advance, including possibly weighing it.

For those who prefer to do their own calculation: Matzah has an average carb factor of 0.75 (75% of its weight is carbohydrates). Whole wheat matzah has almost 12 grams of dietary fiber per 100 grams, allowing one to deduct 4 grams per piece.

Hand Matzah

There are about 10 pieces of matzah per lb. (22 pieces per kilogram). In such a box, each piece weighs approximately 46g and has approximately 35 g of carbs per matzah. Note if there are less matzos in the box, the carb amount per matzah will increase.

Machine Matzah

One whole machine matzah (rectangular) weighs about 30-35g, which is between 23 and 27g of carbs per matzah (depending upon the brand).

A very thin matzah is approximately 30 grams; a “regular” matzah is approximately 40 grams; a thick matzah is approximately 50 grams.

II. The Arba Kosos (Four Cups)

A. Wine

Cup Requirements: The cup must hold at least a revi’is (3.8 fl. oz., or 112 ml).

Minimum shiur to drink to fulfill Arba Kosos: One must drink at least 1.9 fl. oz. (56 ml) for each of the four cups.

Additional Requirements:

  • The lowest percentage of alcohol that may be used for the four cups is 4%.
  • One should drink each of the four cups of wine within a span of 30 seconds.

B. Diluting Wine with Grape Juice and Water

Higher carbohydrate wine may be diluted in the maximum ratios listed below. These ratios allow the wine to retain enough of its properties to qualify it being used for the four cups:

WineGrape JuiceWater
1/32/3
1/31/31/3
1/32/3 (see NOTE below)

NOTE: The diluted beverage should contain at least 4% alcohol to fulfill the obligation of drinking wine at the Seder. 7 If necessary, one may make a mixture of 2/3 water and 1/3 wine (66% water and 34% wine) as long as the diluted amount still contains 4% alcohol. Otherwise, there is a chance that it may no longer be considered wine for the Seder.

The following chart illustrates how much wine to drink:

KosAmount you drinkAmount of wine after dilution
First cup1.9 oz.0.7 oz.
Second cup1.9 oz.0.7 oz.
Third cup1.9 oz.0.7 oz.
Fourth cup1.9 oz.0.7 oz.
TOTAL7.6 oz.2.8 oz.

If these guidelines are followed correctly, as seen in the above chart, one’s total consumption of wine at the Seder will be less than 3 fl. oz. One who wishes to estimate the actual amount that he should drink at the Seder should measure the exact amount that he will need before Yom Tov. He should choose the becher (Kiddush cup) that he will be using at the Seder, and pour the measured amount into it so that he can recognize how much he will be drinking.

The following is an example of how to mix wine and water. Assume one has wine with 10% alcohol content. If he makes a mixture of 40% wine and 60% water, he will have wine with 4% alcohol content, which is enough for the Arba Kosos. This can be done by mixing two cups of wine with three cups of water. He could fill a becher that holds at least 3.8 fl. oz. of this wine and water mixture, and drink at least 1.9 fl. oz. (the amount one may drink to fulfill the mitzvah, when medically necessary). Following the fourth cup, he could ask someone else to be motzi him in the bracha acharona.

To prepare in advance, simply pour two cups of wine into an empty bottle or pitcher and add three cups of water. (The size of the measuring cup does not matter. Just make sure that you use the same cup for the water and the wine). It is always advisable to prepare this bottle in advance and label it as your own “Special Reserve.”

C. Types of wine

The best option for the Seder would be a dry wine, which has very few carbs. [Most dry wines contain approximately 4 grams of carbs per 8 oz. cup.]

If the sour taste bothers you, try adding an artificial sweetener that is Kosher for Passover.

There are also lower carbohydrate sweet wine products which might serve as suitable options.
IMPORTANT: Since alcohol may cause a drop in your blood sugar, discuss with your doctor whether or not to cover the carbs in the wine with insulin. There is more of a chance that wine will cause a low BG (blood glucose) on an empty stomach. If you use pure (unmixed) wine for the first cup, make sure to follow the above guidelines and not overdo your alcohol intake.

Those with Type 2 diabetes should discuss with their health care team and rav whether it is better to drink wine or grape juice. According to Halacha, wine is preferable. Furthermore, grape juice with its high sugar content is not ideal for those with diabetes. However, many of the oral medications used for treating Type 2 diabetes (non-insulin dependent diabetes) are not compatible with alcohol.
Therefore, we suggest showing the wine combination options to your healthcare team. As previously noted, after the dilution the remaining alcohol content of all four cups is not significant. Many healthcare professionals have been very pleased with these dilution options and allow this small total amount of alcohol even with medication.

In addition, those with gestational diabetes (diabetes in pregnancy) or T1, or who are pregnant, should check with their health care team and rav to determine which way to go. Again, show them the charts in order to guide them in their decision.

D. Grape Juice

As noted above, one should use wine or, if necessary, a wine/grape juice combination for the Arba Kosos. If you are unable to drink wine, you may use grape juice instead. If you are unable to drink pure grape juice due to medical reasons for the Arba Kosos (and cannot drink any percentage of wine), you may dilute regular grape juice. When mixing grape juice with water, it is best to make at least 51% of the mixture regular grape juice (i.e., the other 49% is water). In general, “light grape juice” may not be further diluted by the consumer (if there is a necessity, check with the certifying agency). As suggested earlier, you may wish to prepare a “Special Reserve” mixture before Yom Tov and fill a bottle with 4.1 bechers of grape juice and then four bechers of water. This will suffice for the Arba Kosos for both nights; add more using the same ratio as necessary. Keep in mind that as far as diabetes and carb counting are concerned, dry wine is certainly preferable. If you drink grape juice, note that the carbohydrate content of the various grape juices differs. The juices that we tested ranged from 32 to 60g of carbs per cup. Always check the label to ensure you are consuming the least amount of carbs when combining grape juice with wine and/or water.

NOTE: Kedem’s Concord dark grape juice scored 16 grams of carbs in a 4 oz. serving, while the labels on Kedem’s Sparkling Chardonnay and Catawba list 13 and 12 grams of carbs, respectively, in the same 4 oz. serving.

Summary Preparation List

  • Remember that failing to prepare is preparing to fail. If you have everything ready ahead of time, you are less likely to run into problems.
  • Discuss with your rav the shiurim of rov revi’is and mixing wine with water.
  • Select the wine of your choice and check the carb content (remember the meter test).
  • Prepare the right size becher.
  • Train your eye to recognize the amount that you will be drinking during the Seder.
  • Mix wine with water following the instructions of your rav and doctor, and prepare a separate labeled bottle (“Special Reserve”) for this mixture.
  • Try to arrive at an accurate measurement for matzah before Yom Tov.
  • Prepare your choice of glucose for treating hypoglycemia.
  • Review chart and details with your health care team.
  • Prepare all medical supplies, medications, and equipment for Yom Tov and Shabbos.

Finally, remember that Pesach does not have to mean matzah, potatoes and eggs throughout Yom Tov. Instead of high-fat soups and potato kugel, you can substitute other vegetables and vegetable combinations.

JDA has published a cookbook, EnLITEned Kosher Cooking, with more than 140 recipes for Pesach, along with year-round recipes that are easily adaptable. A Hebrew version, BishuLITE, is now also available.

Sugar Substitutes

Many individuals with dietary concerns replace sugar with sugar substitutes. It should be noted that powdered Equal, Splenda and NutraSweet available year-round are NOT Kosher for Passover and may not be used on Pesach.

For a list of available Kosher for Pesach sugar substitutes, click HERE. These products must state Kosher for Passover, or bear a ‘P’ next to the kosher symbol.

1. This means for each mitzvah one eats the designated amount within a 4 minutes span. For example, in case of a medical condition one may eat 1/4 of a machine matzah within a four minute span to fulfill the mitzvah of Achilas Matzah. The same amount within the same span of time should be done for Koreich (with a kezayis of maror) and then for Afikomen.
1a.For a detailed discussion of the various opinions regarding shiurim at the Pesach Seder see HERE.
2. This assumes the whole hand matzah (before it is broken) has a diameter of at least 10.5 inches, which means the entire matzah has an area of 86.6 sq. in. Hence, 1/4 of the matzah equals 21.7 sq. in. This is the minimum shiur for someone with a medical condition. If someone requires shiurim even smaller than this, he should consult his rav. For a discussion of such shiurim, see footnote 107 of “Halachos of the Pesach Seder” HERE.
3. This assumes a full rectangular machine matzah is 7“ x 7“, which means the entire matzah has an area of 49 sq. in., hence, 1/4 of the matzah equals 12.25 sq. in. (This also means that one could eat a piece of matzah that is square, each side with a length and width of 3.5 in.) This is the minimum shiur for someone with a medical condition. It should be noted that Pupa Tzelem hand matzos are generally thinner than machine matzos. Therefore, one needs a larger amount of square inches for hand matzos than for machine matzos.
4. For Koreich, see “Halachos of the Pesach Seder” HERE.
5. This assumes the whole hand matzah (before it was broken) had a diameter of 10.5 in., which means the entire matzah has an area of 86.6 sq. in., hence, 1/2 of the matzah is 43.3 sq. in.
6. This assumes a full rectangular machine matzah is 7” x 7”, which means the entire matzah has an area of 49 sq. in. Hence, 1/2 of the matzah is 24.5 sq. in. (This means one could eat a piece of square matzah that is 5 in. on each side.) Regarding thickness of matzos, see footnote #3.
7. This is to fulfill the obligation of wine. If one cannot drink wine, he can fulfill his obligation with grape juice. This will be discussed later.
