The liquid portion has coffee with a non-oxygen gas dissolved therein and the headspace contains at least approximately 3% oxygen and an amount of a non-oxygen gas. A method of manufacturing the coffee includes dissolving oxygen into a liquid coffee product and packaging the liquid coffee product with oxygen dissolved therein into a sealed container. ## Claims ### Claim 1 A method of manufacturing cold brew coffee comprising: dissolving oxygen into a liquid coffee product brewed at a temperature less than 50° C. and packaging said liquid coffee product with oxygen dissolved therein into a sealed container wherein the sealed container has a partial pressure percentage of oxygen of at least approximately 3%. ### Claim 2 (depends on 1) The method of claim 1, wherein said container is a single use container. ### Claim 3 (depends on 2) The method of claim 2, wherein said container is a metal can. ### Claim 4 (depends on 1) The method of claim 1, wherein the container is a bottle. ### Claim 5 (depends on 1) The method of claim 1, wherein the brew temperature of the liquid coffee product is 3 to 15° C. ### Claim 6 (depends on 1) The method of claim 1 further comprising: feeding a coffee product brewed at a temperature less than 50° C. from a vat into the container, wherein between the vat and container, the dissolving step occurs; dispensing a non-oxygen gas into the container, the non-oxygen gas being a liquid when dispensed; and sealing the container. ### Claim 7 (depends on 6) The method of claim 6, wherein the container has a headspace substantially including only oxygen and the non-oxygen gas. ### Claim 8 (depends on 6) The method of claim 6, wherein the dispensing step is done at a first rate measured in gallons per minute (gpm) and the dissolving step is accomplished by supplying a pressure of oxygen at a second rate measured in positive net pounds per square inch (psi) into an infuser such that the first rate divided by the second rate is a ratio in the range of 0.1-10 gpm/psi. ### Claim 9 (depends on 8) The method of claim 8, wherein the ratio is 1-5 gpm/psi. ### Claim 10 (depends on 1) The method of claim 1, wherein after the step of dissolving and prior to the step of packaging, the coffee is recirculated in a holding tank until the coffee having dissolved oxygen therein reaches an oxygen level of 10-40 ppm. ### Claim 11 (depends on 1) The method of claim 1, wherein the partial pressure percentage of oxygen is less than 10%. ### Claim 12 (depends on 11) The method of claim 11, wherein a total pressure of a gaseous portion of the sealed container in atmospheres times the partial pressure percentage of oxygen defines a pressure ratio which is 0.03-0.16. ### Claim 13 (depends on 12) The method of claim 12, wherein the pressure ratio is approximately 0.1125. ### Claim 14 (depends on 6) The method of claim 6, wherein the non-oxygen gas is nitrogen. ### Claim 15 A cold brew coffee product comprising: a sealed container comprising a liquid portion and a headspace; the liquid portion comprising coffee brewed at a temperature less than 50° C. with a non-oxygen gas dissolved therein; the headspace containing at least approximately 3% oxygen and an amount of the non-oxygen gas. ### Claim 16 (depends on 15) The product of claim 15, wherein the non-oxygen gas is nitrogen. ### Claim 17 (depends on 15) The product of claim 15, wherein the headspace has a total pressure between 1-4 atmospheres when the liquid portion is at a temperature of 3° C. ### Claim 18 (depends on 15) The product of claim 15, wherein the headspace contains approximately 3-6% oxygen. ### Claim 19 (depends on 18) The product of claim 18, wherein the liquid portion has a pH of 4.6 or greater. ### Claim 20 A method of manufacturing a stable nitrogen infused coffee product comprising the steps of: dissolving oxygen into a liquid coffee product brewed at temperature less than 50° C.; packaging the coffee product having dissolved oxygen therein into a container; dispensing nitrogen into the container to produce a nitrogen infused coffee product; and sealing the container, wherein the nitrogen infused coffee product has a pH of 4.6 or greater and remains free of Clostridium botulinum (C. bot) when stored at refrigerated conditions. ### Claim 21 (depends on 20) The method of claim 20 wherein the pH is 5.0 or greater. ### Claim 22 (depends on 20) The method of claim 20 wherein the pH is 5.5-6.5. ### Claim 23 (depends on 18) The product of claim 18 wherein the pH is 5.0 or greater. ### Claim 24 (depends on 18) The product of claim 18 wherein the pH is 5.5-6.5. ### Claim 25 A cold brew coffee product comprising: a sealed container comprising a liquid portion and a headspace; the liquid portion comprising coffee brewed at a temperature less than 50° C. with oxygen and a non-oxygen gas dissolved therein; the headspace containing oxygen and an amount of the non-oxygen gas; the liquid portion having a pH of 4.6 or greater wherein the product is free of Clostridium botulinum (C. bot). ### Claim 26 (depends on 25) The product of claim 25 wherein the pH is 5.0 or greater. ### Claim 27 (depends on 25) The product of claim 25 wherein the pH is 5.5-6.5.
