Presentation for

The Old and The New -how to get the best out of

your finings products

Who are ab Vickers - What do we do?

Design, manufacture and market products for:

• Wort/beer clarification• Colloidal, flavour and colour stabilisation• Foam stabilisation• Anti foam• Yeast nutrition • Brewing enzymes

ANDProvide technical support and consultancy on all aspects of the brewing process

Brewery fining products

• Carrageenan• Isinglass • Auxiliaries• Alternatives

Carrageenan/Copper Finings/ Compac CG CGT

•Widely used•Meat•Dairy•Confectionery•Juice and Beverages•Sauces / Dressings•Cosmetic/Pharmaceutical/Nonfood

•Many applications•Suspension•Texturising•Thickening•Binding•Gelling•Clarification

Product Presentation for

Carrageenan - Mechanism,

Benefits

•Clarification of wort by removal of haze forming particles

•Improved beer filtration

•Brighter beer downstreamcontrol 10

wort clarification

•Hot break compaction

•Increased wort yield

•Reduced trub carry over

Fined

Unfined

•Granules

•Added to copper 5-10mins before end of boil. Can be added to whirlpool as well

•100% active material

•Tablets

•As with granules but contains dispersant – can be added to copper or whirlpool. Whirlpool must be dry otherwise tablets can stick.

Factors affecting the efficiency of Comapc CG

• Add correct form for particular application

• Check addition rate regularly, particularly when changing:

– Brewhouse procedures • Boil Time• Evaporation Rate

– or raw materials.• Malt season / Variety• Adjunct / Malt ratio• Liquor treatment• Hop Loading

Copper fining optimisation method

1000ppm copper fining liquid, 1-2lt wort sample 5 minutes before the end of the boil, 100ml glass bottles + caps, 5ml syringe, kettle and 100ml graduated cylinder

Materials 1

Label the bottles and dose a range of with copper finings

liquid (1ml = 10ppm)

3

Transfer the hot wort sample into plastic jug

Measure 100ml hot wort and transfer into glass bottles

4

Cap bottles and shake well (3-5 secs)

5

Place bottles under running cold water for 10-15

minutes while agitating

Bring the untreated wort to the boil

ISINGLASS

Whole Maw

Forms of Isinglass

• Paste – Concentrated 1:25 dilution– Not heat sensitive– Long shelf life– More input from customer– Problems - SO2 cutting

• Concentrated – 1600TN requires 1:3 breakdown– Must keep cold– Shorter shellfire

• RFU– 650TN - use as is– Shorter shellfire

But how does it work???

Collagen Helical Structure

Addition to Cask

• Ensure cask is cold.• If using auxiliary it should be added at start of fill,

isinglass at the end of fill• If auxiliary is used in FV or RT, then isinglass can be

added near to the start.• Always use RFU strength - a less viscous material

mixes better.

Addition FV-CT

• Ideally isinglass should be added in line throughoutthe beer transfer between FV and CT ideally at point of turbulence

• Main points– A less viscous solution will be easier to disperse – Beer first isinglass second– Rouse if possible

• Beer should be chilled prior to isinglass addition, or immediately afterwards – chill haze formation

Optimisation

• Depends on style of beer• Large Fluffy Bottoms in cask• Too little not bright or poor filterability• Factors which can affect addition rate

– pH– Yeast count– Solids loading of beer– Process changes– Malt variety

– increases fining speed– final beer clarity– can cause fluffy sediments

• Options- type- addition point/contact time- addition rate- storage

Why use auxiliary finings…..

Auxiliary Finings

Types– Acidified sodium silicate solution SAF

• Strong ionic charge / aggressive / high sediments• high negative charge density• Shorter shelflife

– Blends AES– Polysaccharides

• carrageenan, gum arabic, methyl celluloses AMF

Addition point– Prior to isinglass, contact time a few minutes, a few hours (ideal), a few days - layering in tank

Storage– Temperature and shelf life requirements– SO2 depletion– Mild steel

Alternatives

• Centrifugation• Vegan / vegetarian fining products

– Silica Sols/ poly sach and sol blends– Protofine - Pectin.

PROTOFINE

• Novel Fining agent• Vegan / Vegetarian compliant• Pectin derived• Comparable fining performance to

isinglass - for Keg and filtration• Addition rates – tighter control than

isinglass• Sediments can be a little higher
