A sealed barrel [of wine that is terumah] makes a mixture miduma whatever the ratio [between it and the other barrels].
What is implied? When a sealed barrel [of wine] that is terumah becomes mixed with several thousand sealed barrels [of ordinary wine], the entire mixture becomes miduma.1This follows the principle devar shebiminyan lo betal: "The presence of an object that is sold by number is never considered insignificant." Since these objects are sold by number, each one is considered important and it is not appropriate to say that one is insignificant (Hilchot Ma'achalot Assurot 16:1-3). If the barrels are opened, [the presence of the terumah] is nullified when 101 times its contents are present.2For once the barrels are opened, they are no longer considered as important. It is, however, forbidden to open the barrels, for this would be considered as purposefully nullifying a forbidden substance and that is prohibited (Radbaz).

When a sealed barrel [that contains terumah] becomes mixed with 100 barrels and then one falls into the Mediterranean Sea, they are all permitted. We assume that it is the one that is terumah that fell in. This is not the case when a fig falls into 100 figs. In the latter instance, it is necessary to set aside one [fig].3And give it to a priest. The Jerusalem Talmud (Terumot 4:7) records a difference of opinion concerning this matter between Reish Lakish and Rabbi Yochanan. Reish Lakish's opinion is the one cited by the Rambam. Rabbi Yochanan, however, differs and maintains that the same law applies even with regard to figs. The Rambam rules according to Reish Lakish's opinion, for the Babylonian Talmud (Zevachim 74b) mentions his view only and not that of Rabbi Yochanan. See also Hilchot Avodat Kochavim 7:10 where the Rambam issues a similar ruling.
The Ra'avad does not accept this ruling. He maintains that the Babylonian Talmud mentions Reish Lakish's opinion only in connection with the discussion of another minority view. Hence, it is not necessary to mention Rabbi Yochanan's view.
[The rationale for the distinction is] that a barrel that falls into the sea is noticeable. A fig and the like which fall are not noticeable.

When a sealed barrel [that contains terumah] becomes mixed with 100 barrels and one of them is opened,4Inadvertently. It is forbidden to open such a barrel intentionally. he should remove one hundredth of it,5More precisely, 1/101. I.e., the percent of the mixture that is terumah. This is given to a priest. and then he may drink the barrel.6It is true that this ruling is somewhat problematic. For if the barrel is in fact terumah, the entire barrel, not only the hundredth portion, must be given to the priest. And if it is not terumah, it is permitted to drink it in its entirety. Nothing need be given to the priest.
The Ma'aseh Rokeach explains the reason for the stringency. Were this safeguard not taken, one might permit the barrels even when they were all opened.
The other barrels are, however, forbidden until they are opened. Whenever any one of them is opened, he should remove the percentage that causes the mixture to be miduma and drink the remaining hundred portions.
If a barrel [containing terumah] became mixed with 150 barrels and 100 of them were opened, one should remove the percentage that causes the mixture to be miduma, i.e., one barrel and drink [the remaining barrels]. The remaining 50 are still forbidden; we do not presume that the barrel that was terumah was among the majority [that were opened].7Although when considering those barrels, it is necessary to give a barrel to a priest because of the suspicion that one is terumah, we are still stringent regarding those remaining. Even if there are several thousand barrels, they are all considered miduma. Whenever any one is opened, he should remove one hundredth of it and then he may drink the remainder [of that barrel]. The other barrels, however, are miduma,

We have already explained in Hilchot Ma'achalot Assurot8Chapter 16, Halachah 1. that a leavening agent or a spice9Based on Hilchot Ma'achalot Assurot 16:26, the Radbaz states that this same law applies if terumah is used to cause cheese to harden. causes a mixture to be forbidden regardless of how small the amount is mixed in.10I.e., the standard ration of 1/101 is not effective to nullify the terumah. In his Commentary to the Mishnah (Orlah 2:4; Terumot 10:2), the Rambam explains that since the effects of the terumah are evident in the food - it rises or it is spiced because of it - we cannot say that the terumah is nullified. Therefore if a person pureed an apple that was terumah and put it in a dough and it caused [the dough] to leaven, the entire dough becomes miduma and is forbidden to non-priests.

We have already explained13Chapter 13, Halachah 2; Hilchot Ma'achalot Assurot 15:1,6. that if terumah becomes mixed with a substance of a different type, [the mixture is forbidden if the terumah] imparts its flavor [to the mixture]. Therefore, [the following laws apply when] a diced onion is cooked together with other food. If the onion is terumah and the other food is ordinary produce and it is flavored by the onion, the other food is forbidden to non-priests. If the onion is ordinary produce and the cooked food is terumah and the flavor of the cooked food was imparted to the onion, the onion is forbidden [to non-priests].14How do we know whether the flavor of the terumah was imparted to the mixture. We give it to a priest to taste (ibid. 15:29).

[The following laws apply if] lentils were cooked and then a dry onion was placed among them: If the onion was whole, it is permitted.15In his Commentary to the Mishnah (Terumot 10:1), the Rambam explains that this applies whether the onion is terumah and the lentils ordinary produce or the reverse. In both instances, since the lentils are already cooked and the onion is whole, there is little likelihood that one will absorb the flavor from the other. If it was diced, [the ruling depends on whether] its flavor was imparted.16Here also the same principle applies whether it is the onion or the lentils which are terumah. Since the onion is diced, it will both impart and absorb flavor easier. If he cooked the onion with the lentils, whether it is whole or diced, we estimate whether it imparted its flavor.17Since the onion is cooked, even if it is whole, it can both impart and absorb flavor easily. With regard to the remainder of the cooked food,18I.e., in addition to the lentils. regardless of whether the onion was placed upon it after it was cooked or cooked with it, or whether it was whole or diced, we estimate whether it imparted its flavor.19As the Rambam proceeds to explain, lentils are considered as being unique. Once they are cooked, they do not absorb flavor from other foods easily. Other foods are more absorbent. Even after they have been cooked, they may absorb the flavor of the onion.
Why do we not estimate [whether flavor was imparted] when a whole onion was placed among cooked lentils? Because it does not absorb from them, for it is whole, nor does it impart [flavor] to them, because they have already been cooked. If the onions were soft,20The Kessef Mishneh suggests that the text should read rabbim, "many," instead of rachim, "soft;" i.e., one onion that is whole will not impart that much flavor, but several onions will. it is considered as if they were diced. Similarly, if its tip or its outer shell21Once the tip or the outer shell is removed, its flavor will be imparted easily even though it is still whole. was removed or it was moist, it is considered as if it was diced. Wild onions, whether moist or dry, whether whole or diced, we see if they have imparted their flavor.

When one pickles vegetables that are ordinary produce with those of terumah, they are permitted to non-priests22In certain contexts (see Hilchot Ma'achalot Assurot 15:34), pickling is considered as cooking. Nevertheless, in this instance, the Rambam rules leniently. with the exception of onions, scallions, and garlic.23Because their sharp and pungent taste nature causes their flavor to be imparted to any vegetables pickled with them [the Rambam's Commentary to the Mishnah (Terumot 10:10)]. [With regard to these species,] if one pickled vegetables that are ordinary produce with onions that are terumah or onions that are ordinary produce with onions that are terumah, they are forbidden to non-priests. If one pickled vegetables that are terumah with an onion that is ordinary produce, the onion is permitted to non-priests.24For the onion will not absorb the flavor of the other produce.

If, however, they were both whole or the olives that were terumah were crushed and those that were ordinary produce were whole, they are permitted, because those that are crushed absorb from those which are whole.

When wine that is terumah falls on produce, one may wash the fruits and they are permitted.37The Radbaz notes that in Hilchot Ma'achalot Assurot 16:32, the Rambam writes a similar law with regard to wine associated with idol worship that fell on produce. There, however, he rules stringently, stating that the fruits are forbidden if the wine is poured upon them while they are broken open. The Radbaz explains that the Rambam did not mention the point here, because he relied on what he had stated earlier. Indeed, if the fruit was broken open and the wine improved its flavor, it should be sold to a priest at the price of terumah. Similarly, when oil that is terumah falls on produce, one may wash the fruits and they are permitted.38Even though oil is more likely to cling to fruit than wine, it is sufficient to wash the fruit. Generally, oil does not improve the taste of fruit (Radbaz).
When oil [that is terumah] falls on [ordinary] wine, one should make it coagulate39For in this way, the oil can be removed without it mixing with the wine. Similarly, oil impairs the flavor of wine (ibid.). and the wine is then permitted to non-priests. If [oil that is terumah] mixes with brine, it should be made to coagulate, then the upper layer of the brine should be removed40This stringency is necessary, because oil improves the flavor of brine (ibid.). so that all the brine that has the taste of oil will be removed.

A pot in which terumah was cooked should not be used to cook ordinary produce. If it was cooked in it, it causes it to be forbidden if its flavor is recognizable. If he washes out the pot with wine or with water, it is permitted to cook in it.41The Ra'avad questions the Rambam's ruling, asking why this instance is different from the laws involving non-kosher food absorbed in a utensil. In that instance, it is not sufficient to wash out the utensil, one must perform hagalah, boiling water in the utensil to purge the absorbed matter. The Radbaz explains that the Rambam maintains that this concept applies with regard to sanctified foods and other prohibitions, but not with regard to terumah. The rationale is that if the priests consider the terumah insignificant - as would be the case with regard to terumah absorbed in a pot - it is no longer of consequence. He draws support for this explanation from the mishnah in Terumot 11:8 (quoted in Chapter 11, Halachah 15) which states that after one pours out the contents of a jug of wine of terumah, one can pour ordinary wine into the container even if there is a small amount of residue from the previous wine. This explanation is also given in one of the responsa ascribed to the Rambam in a response to a question concerning this subject by the sages of Lunil. The Kessef Mishneh also cites these ideas and states that the reason the Rambam requires that the pot be washed out is because the contents are being cooked. If they were not to be cooked, even washing would not be necessary. If he cooked [terumah] in part of the pot, it is not necessary to wash out the entire pot, only the place where it was cooked.42This leniency applies only with regard to terumah and not to prohibited food absorbed in a utensil. The rationale is the same as in the previous note: Since the priests consider this terumah insignificant, we do not show concern about it (Radbaz).

The great terumah, terumat ma'aser, challah,43The portion of dough that must be separated and given to a priest. and the first fruits are all referred to as terumah.44See Chapter 10, Halachah 4. With regard to terumat ma'aser, [Numbers 18:26] states: "And you shall remove the terumah of G‑d from it" and [ibid. 15:20] states that it should be "like the terumah of your grain heap."45This verse refers to challah; or it is comparing challah to the great terumah. Perhaps a scribal error crept into the text and this was intended as support for the following clause. The Radbaz, however, gives an explanation why it was included here.
With regard to challah, [ibid.] states: "You shall separate challah as terumah." And [Deuteronomy 12:17]: "You may not eat in your gates the tithes of your grain, your wine, and your oil,... and the terumah of your hand." Now there are no substances that are required to be brought [to Jerusalem to be eaten] that are not explicitly mentioned in the verse except the first fruits. Thus the phrase "the terumah of your hand" can be applied to them. Thus we see that they are [also] called terumah.

Therefore the laws regarding partaking of all four types of substances and mixtures of them and other substances are the same. All can be nullified in a mixture of 101 times the original substance. They are also all combined with each other.46I.e., to cause a mixture to be forbidden to non-priests. If they become impure, they should all be burnt. The laws that apply to terumat ma'aser that is demai,47Produce from which we are unsure that the tithes have been separated. are the same that apply to terumat ma'aser separated from produce [from which the tithes were] definitely [not separated]. It is only that its violation is not punishable by lashes.

Anyone who partakes of terumah should recite the blessing for that particular food and then recite the blessing:48For partaking of terumah is a mitzvah and we are required to recite a blessing before the observance of all mitzvot (Kessef Mishneh). "[Blessed are You... who has sanctified us with the holiness of Aaron and commanded us to partake of terumah."49See Hillchot Bikkurim 1:2. We have received the tradition and observed that people would recite this blessing even when partaking of challah separated in the Diaspora.50Even though it is only a Rabbinic commandment. For even partaking of sacred foods from the boundaries [of our Holy Land] is like service [in the Temple],51Pesachim 72b relates that one day Rabbi Tarfon did not come to the House of study. Rabban Gamliel rebuked him for his absence. Rabbi Tarfon answered that he was carrying out priestly worship. Rabban Gamliel asked him how that was possible, for they lived in the era of the Temple's destruction. Rabbi Tarfon replied that partaking of terumah was equivalent to serving in the Temple. as [Numbers 18:7] states: "I have granted you your priestly service as a gift."
