## CPC

- C12C 7/047: part of the mash being unmalted cereal mash
- C12C: BEER; PREPARATION OF BEER BY FERMENTATION (ageing or ripening by storing C12H1/22; methods for reducing the alcohol content after fermentation C12H3/00; methods for increasing the alcohol content after fermentation C12H6/00; venting devices for casks, barrels or the like C12L9/00); PREPARATION OF MALT FOR MAKING BEER; PREPARATION OF HOPS FOR MAKING BEER

## Abstract

Beer brewed from malted barley and having a rice adjunct can be produced at higher gravity cold wort concentrations without excessive viscosity build-up by using low gel point rice.

## Claims

### Claim 1

In a method of brewing beer wherein wort is produced from a mash consisting essentially of water, malt, and a substantial amount of rice as an adjunct, and the malt is present in a greater amount than the rice, the improvement comprising using as said rice, strains of rice having a gel point of 70.degree. C. or less, and using increased amounts of malt and rice in direct proportions in the mash to obtain a wort having a cold wort concentration of 16.degree. Balling or higher to produce a high gravity beer, said cold wort concentration of 16.degree. Balling or higher resulting solely from the increased amounts of malt and rice in the mash.

### Claim 2 (depends on 1)

The method of claim 1 wherein the strain of rice used has a gel point of from about 63.degree. C. to 70.degree. C.

### Claim 3 (depends on 1)

The method of claim 1 wherein the strain of rice used is selected from a group consisting essentially of Mochi Gomi, Brazos, Nortai, Nato and Mars.

### Claim 4 (depends on 1)

The method of claim 1 wherein the rice used is Mochi Gomi.

### Claim 5 (depends on 1)

The method of claim 1 wherein the rice used is Nortai.
