We specialize in the superb quality brewing aids from AllTech
Product Categories;
a liquid fungal glucoamylase for the creation of light beers, Convertase AG-300 is used to rapidly break down the 1-4 glucosodic bonds, and, at a slower rate, the 1-6 bonds in liquefied starch. Recommended usage is in the fermenting vessel. Optimum temp. is 60deg C, range 10 to 70 deg. C. Note that glucoamylase will convert all starches to glucose. Care must be taken to isolate this enzyme in the brewery. Contamination of other beers can cause sweetening of product during storage, and even after bottling.
Available in 1 Litre and 20 Litre sizes
Convertase MG-30 (shortly to be re-named Bio Cellulase)
a liquid fungal cellulase that ensures quicker run-off and improved filtration by removing beta-glucans from the mash. Suggested for use with poorly modified malts, mashes with high adjunct ratios, and other cereals containing beta-glucans. Optimum temperature 50 deg. C., range 4-70 deg C.
Available in 1 Litre and 20 Litre sizes
Note: Crosby & Baker also sells the following enzyme, not produced by Siebel/Quest:
Fungal Alpha Amylase:
Used in fermentation or cold storage to hydrolyze 1-4 glucosidic links in malt and adjunct starches. Leaves the 1-6 links, and is therefore self-limiting, converting just some starches and dextrins into maltose. Recommended for light beers, or to prevent starch problems in storage.
Available in 1 and 5 Lb. sizes:
AllFloc from Alltech
Enhanced Kappa Carrageenan reduces dosage rates and improves flocculation! For addition to the boiling kettle 15-20 minutes before the end of boil. Usage approx .4 - 1.2 oz. per 10 bbl. AllFloc is prized for its consistency and high potency. Results include improved hot and cold breaks, trub compaction, improved filtration, and some chillproofing.
Available in 5 Lb., and 25 KG (55 Lb) packs
Sodium Erythorbate (was Siebel Brand Brewing Anti-Oxident)
protects finished beer against dissolved and head-space oxygen during brewing and packaging. Protection against oxidation continues during shipping, warehousing and retail storage. Extends shelf-life, maintains and stabilizes flavor, palatability and brilliance.
Sold in 8 lb. Containers
Chr. Hansen Anti-Oxident (was iebel Brand Anti-Oxident)
mostly Sodium Erythorbate, but also contains metabisulfite, which generates S02 as an additional anti-oxident.
Sold in 9 Lb. and 100 lb. Containers
AYF Yeast Nutrient from Alltech
a superbly balanced blend of minerals, proteins, amino acids and vitamins essential to optimize yeast activity during fermentation, notably of high adjunct beers. Usage is approx. .8 - 1.6 oz per 10 bbl. Compare these dosage rates to other products, and you'll switch! Benefits are improved attenuation, increased consistency of fermentation rate and beer flavor.
Available in 5 lb. and 25 kg (44 Lb) sizes
Ferm-Cap S:
A silica-based emulsion with the ability to increase fermentation capacity and improve hop utilization with no negative effect on final beer head stability. Can reduce required fermenter head space from 20% to about 5%. Product is removed from the beer on yeast cells and tank walls.
Available in 1 liter, 1 gallon and 20 kg sizes
AllFine from Alltech
A purified and standardized form of fish collagen, with a small amount of sodium metabisulfite as a preservative. A free-flowing white powder, mixed into solution in a simple mixer, and normally added as beer is transferred from fermenter to storage. Usage is approx .4-1.2 oz. per 10 bbl. for both ales and lagers.
Available in 3 lb. and 25 kg (44 lb) packs
Clearfine:
A unique blend of animal collagen and polysaccharides which, when added to beer during cold storage, results in rapid precipitation and compaction fo yeast and insoluble materials. Usage approx. .8-2.4 oz. per 1- bbl. Benefits are simpler, quicker preparation that isinglass, improved yeast separation, reduced beer loss and improved filter performance. Separated material forms a dense, compact layer.
Available in 1 lb. and 5 lb. sizes
